海外TECH	DEV Community	Learn the Basics of RegEx in JavaScript	https://dev.to/thedevdrawer/learn-the-basics-of-regex-in-javascript-4kdh	Learn the Basics of RegEx in JavaScriptIn JavaScript regular expressions RegEx can be used to match strings or parts of strings To create a regular expression you can use the RegEx constructor or the literal notation pattern flags View This On YouTube Using the RegExp Constructorlet pattern new RegExp hello let input hello world let result pattern test input trueconsole log result Using the Literal Notationlet pattern hello let input hello world let result pattern test input trueconsole log result In addition to the test method you can use other methods such as exec match search and replace to work with regular expressions Using match Methodlet pattern d g let input I have apples and oranges let result input match pattern console log result RegEx FlagsYou can also use flags to modify the behavior of the regular expression Some common flags include g global i case insensitive and m multiline Here is an example of using the i flag let pattern hello i let input Hello World let result pattern test input trueconsole log result In this example the i flag makes the regular expression case insensitive so it matches Hello as well as hello Patterns and What They MeanWhat does pattern d g mean in my third example The regular expression d g is made up of three parts the forward slashes the pattern d and the flag g The forward slashes define the start and end of the regular expression The pattern d is a character set that matches one or more digits The d shorthand character is set for any digit and the quantifier specifies that one or more of the preceding elements must be present So it will match one or more digits together The flag g stands for global which means it will find all matches rather than stopping after the first match Without this flag the regular expression would only return the first match So the regular expression d g matches one or more digits together and returns all occurrences of that match in the input string In the third example code it will match all digits in the input string What About String ReGex Using Expressions In JavaScript you can also use regular expressions with string methods such as match search replace and split These methods allow you to work with strings in a more powerful way using the pattern matching capabilities of regular expressions match Methodlet input Hello World let result input match world i World index input Hello World groups undefined console log result In this example the match method searches the input string for the first occurrence of the pattern world case insensitive It returns an array containing the matched string replace Methodlet input Hello World let result input replace world i javascript Hello javascript console log result In this example the replace method searches the input string for the first occurrence of the pattern world case insensitive and replaces it with javascript search Methodlet input Hello World let result input search world i console log result In this example the search method searches the input string for the first occurrence of the pattern world case insensitive It returns the index of the first character of the matched string split Methodlet input Hello World let result input split s Hello World console log result In this example the split method splits the input string into an array of substrings using the pattern s one or more whitespaces as the separator You can also pass the regular expression object to these methods instead of a string representation of the pattern For example you can reference how it was done in the third example Getting Domain Variables From a StringThis regex is very helpful if you are creating your own single page application router You may have seen it in my other tutorials or even in my other videos To get the domain from a string using a regular expression you can use the match method along with a regular expression pattern that captures the domain part of a URL Here s an example of how you can do this let input hashtag let pattern https n www n im let result input match pattern console log result console log result thedevdrawer comIn this example the regular expression pattern is as follows matches the start of the string https matches the optional http or https protocol the quantifier makes this group optional n matches the optional username and symbol which typically comes before the domain in a URL The quantifier makes this group optional www matches the optional www subdomain the quantifier makes this group optional n matches one or more characters that are not or a newline and captures the domain name im are the flags i for case insensitive and m for multilineThe match method searches for the first match of the regular expression pattern in the input string and returns an array containing the matched string and any captured groups In this case the domain is captured in the first group result of the returned array In this example the input is hashtag and the output will be at index and thedevdrawer com at index Get The Query and HashTo get the query and hash from a URL using a regular expression you can use the match method along with separate regular expression patterns for each part Here s an example of how you can do this let queryPattern let hasOnlyPattern let query input match queryPattern let hash input match hasOnlyPattern console log query console log hash In this example we use two regular expression patterns uses to match any character except the symbol and captures everything after the question mark up until the symbol if any matches the hash symbol followed by zero or more characters and captures everything after the hash The parentheses around create a capturing group that allows us to extract just the hash fragment The match method searches for the first match of the regular expression pattern in the input string and returns an array containing the matched string and any captured groups In this case we extract the captured group at index the second item in the array to get just the query string and hash fragment In this example the input is hashtag and the output will be query query value hash hashtag Get The Query ValueTo just get the value from the query string using a regular expression you can modify the regular expression pattern to capture only the value part of the key value pair Here s an example of how you can do this let queryOnlyPattern amp query amp let match input match queryOnlyPattern console log match In this example the regular expression pattern is as follows amp matches either the question mark or ampersand character that starts a key value pair but doesn t capture it query captures the key query in a group amp matches the equal sign and captures everything after it up until the next ampersand or hash symbol The parentheses around amp create a capturing group that allows us to extract just the value part of the key value pair The match method searches for the first match of the regular expression pattern in the input string and returns an array containing the matched string and any captured groups In this case we extract the captured group at index the third item in the array to get just the value of the query key In this example the input is hashtag and the output will be value value NOTE Keep in mind that this regex pattern is designed to match a specific format of URL and may not work for all types of URLs or query hash strings It may require tweaking or additional patterns to match other formats Hopefully this helped you understand regular expressions in JavaScript in case you had any questions about some of my previous videos that used them If you have any questions feel free to leave a comment below	2023-02-22 17:32:50

海外TECH	DEV Community	The what and why of CI	https://dev.to/aneshodza/ci-crash-course-2eo4	The what and why of CIThis tutorial only talks about what and why There is no implementation That will follow in another tutorial What is continuous integration CI Continuous integration CI is the practice of automating the integration of code changes from multiple contributors into a single software project says Atlassian But what does that even mean Continous integration is a lot of people and resources working together to automate code release as much as possible That includes the programmer writing his code and pushing it into a branch which is named after the git conventions Those are feature description kebap cased for featuresbugfix description kebap cased for bugfixeshotfix description kebap cased for hotfixesThose then have to run trough a QA quality assurance phase where another programmer reviews the code and shows what can be changed Important is that the branch includes new tests for whatever feature was added If it was a bugfix there should be regression tests which test if the bug is still happening or not At the same time a CI Tool is running in the background which executes the tests and returns if they passed or not That can look as follows If you are interested in seeing this in action check out Ananke I ll write an article about it so stay tuned Why to set up a proper CISetting up a proper CI is probably the most important step of a project that is meant to last and be expanded for years to come It makes the code Maintainable er Readable er Bug free er Secure er Notice the er at the end That s because it s not a catch all solution that makes code automatically perfect But having a good QA quality assurance having tests having automatic linters having tools like brakeman to check for obvious security risks makes you less prone to those issues This is what a tech stack may look for my projects and other Rails projects like Ananke Everything highlighted is only used to make the code long term maintainable MaintainabilityFirst and foremost The code is better maintainable Good and readable tests can act as a sort of Handbook for the code Real life exampleLet s say I am new in a project and I need to extend the timer units controller rb but I have no idea how it works or what it does I can just go into the time units controller spec rb and read the tests They explain in hopefully English what every function is supposed to do InsuranceNext tests act as insurance that everything you did still works Often times when a programmer implements a new feature it can cause other stuff to break By writing good tests that make sure everything does what it should we can prevent that kind of stuff from happening ReadabilityStyle checks such as eslint stylelint etc should de a part of your CI They make sure that the code comforts to a certain style so a project doesn t mix a hundred different styles by the hundred different developers that worked on it Keep in mind You can never completely get rid of code written in a certain style but you should try to Fastcheck filesWhat I like to do is make a bin fastcheck file which executes all fast running tests such as linters A fastcheck file may look as follows bin shset epassing truecheck if ne then passing false fi echo Running quick checks if fix then echo Autocorrecting bundle exec rubocop A c rubocop yml check npx stylelint fix scss else echo Note to autocorrect run with fix check bundle exec rubocop D c rubocop yml fail fast check check npx stylelint scss ficheckbundle exec brakeman q z no summary no pagercheckif passing true then echo All checks passed else echo Some checks failed exit fi Manual quality assuranceBesides that a good and harsh QA quality assurance process makes sure that the code has been seen by at least four eyes and upholds certain standards Bug preventionEveryone wants to prevent bugs in their application but sadly it almost never works Creating a bug free application Sadly it s almost impossible to achieve No matter how good you think your application is there will always be bugs That doesn t mean that we just give up and let bugs run rampant in our application we give it our best to prevent them How to prevent bugs with CIAnd that s where a good CI in combination with good versioning comes in Having tests which also try to cover edge cases makes finding bugs really easy Let s run trough a scenario Someone implements a new feature where the user can also pick a background color for his profile page To do that they get a color picker but also an input field Now that input field takes hex codes in this format FFFFFF What the other developer didn t think about was that FFF is also a valid hex code He pushed his code opened a PR and requested a review by us We look trough the code and see that there is no test to check if FFF properly works We write that into our code review and request changes After his push we see The new test fails because the short format is not supported That s how testing should work You write the tests for your new feature and try to simulate very single edge case Then you write the code that makes the tests pass That is called the red green amp refactor process I wont go into that in this article but its definitely a topic you should look up Another useful took which needs good versioning git bisect It binary searches trough your commit history to find new bugs This is not exactly the topic of this article but still important to be mentioned as it shows the importance of a clean git history Regression testsSomething really important are regression tests You write those in the same PR in which you fix a bug The goal of regression tests is to simulate what you did to make the code bug but expect it to not have that bug anymore That s how we can prevent a bug from re appearing In practice that can look as follows SecurityThis pro is actually closely tied to the one before It s the same concept of let s write specs that try to exploit the code That doesn t only prevent a security flaw from appearing but also from reappearing Automatic security checksA lot of frameworks have libraries plugins that can automatically check for obvious security flaws For example Rails has Brakeman You may have already noticed it in my fastcheck file bundle exec brakeman q z no summary no pagerStuff like SQL injections can quickly be caught by brakeman That is really useful and may or may not it definitely has already catch developers implementing places where SQL injections are possible With all that said It shouldn t give you a false sense of security You do probably still have exploits in your application Automatic software updatesFor everyone that has read my article about the demonstration of security flaws already knows how bad things can turn out because a library has issues If I would need to summarize this topic into one word LogShell The problem with rd party software is When they mess up security wise your software can be affected Luckily often times libraries give their best to fix those exploits as quickly as possible That doesn t matter to you tho because you still have the exploitable version How can we automatically prevent those issues What I like to do is also use tools such as depfu which creates pull requests in a set schedule which contain updates to your projects dependencies Disadvantages to having a CIEven tho I m a big fan of having a CI and having version updates and having tests there are obvious disadvantages and this slightly opinionated tutorial wouldn t be complete without listing those In my opinion there are a few of them MoneyMoneyMoneyOkay now jokes aside The disadvantages are mainly money If you want a more serious list Money I m serious Short term Development time which is basically money The money problemThe issue with having a good CI is that both upkeep cost and development time go up Upkeep costWith upkeep cost I mean stuff like running the tests on a CI tool such as semaphoreCI and paying for other tools such as depfu If you don t work on big projects the costs still stay very low From personal expirience I pay about two dollars monthly for my personal projects for semaphoreCI I m still using the free tier of depfu Development speedIn the short term development speed can seriously be impacted by a CI The QA process alone can sometime take up to weeks if everyone that can review doesn t have time On the other hand you also have the writing and maintaining of a good test environment It s really important to go all in when writing tests because having them not test everything can cause the devs to have a false sense of security and check less if stuff actually still works Important In the long term tho I believe that a good CI improves development speed as you don t need to worry as much about a lot of stuff such as Keeping the codebase clean keeping it bug free keeping the versions up to date keeping the software relatively secure etc ConclusionCI s play a very important in dev ops environments today which is why upcoming devs need to learn how to handle CI I hope this article gave you a bit of an insight into how CI works and why we do it If you are more interested in setting this up by yourself in projects I currently have an article about that in the drafts And as always Happy hacking	2023-02-22 17:31:39

海外TECH	DEV Community	Brief introduction to testing in python.	https://dev.to/kabakiantony/brief-introduction-to-testing-in-python-3bfn	Brief introduction to testing in python IntroductionTesting is an essential part of software development and it involves verifying that a piece of software meets its requirements and functions as expected In other words it is the act of checking whether a software product does what it is supposed to do While it is possible to test software manually by using the product and checking if it functions correctly this approach is often time consuming laborious and prone to human error especially in the case of complex systems Automated testing is a more efficient and reliable way of testing software and Python offers a powerful testing framework for this purpose ーunittest PrerequisitesBefore you can write tests in Python you need to have Python installed on your computer and a basic understanding of the language Once you have these prerequisites you can start using unittest by importing it into your code and utilizing the various classes and methods it provides Unittest frameworkTo illustrate how unittest works let s consider a simple example Suppose we have a function that adds two numbers together and we want to test whether it works as expected We can write a test case that checks whether the function returns the correct result for a given input Here is an example that demonstrates this import unittestdef sum a b return a bclass TestSum unittest TestCase def test sum of positive numbers self self assertEqual sum if name main unittest main In this code we import the unittest module and define a function called sum that takes in two arguments and returns their sum We also create a TestSum class that subclasses unittest TestCase In this class we define a test case test sum of positive numbers that checks whether the sum function returns the expected result when given two positive numbers To run the test we simply execute the unittest main function which runs all the tests in the current module When we run this code we should get an output that tells us whether the test passed or failed In this case the test should fail because we expect the function to return but it actually returns Testing conceptsThat simple example demonstrates some of the basic concepts of testing including test cases and assertions A test case is a set of conditions or variables under which we determine whether a piece of software is meeting its requirements In our example the test case is test sum of positive numbers Assertions are statements that check whether a condition is true or false In our example we use the assertEqual method to check whether the sum function returns the expected result In addition to test cases and assertions there are other important concepts in testing including test suites fixtures and mocking A test suite is a collection of test cases that are run together Fixtures are objects that provide a fixed baseline for testing such as a database or a file system Mocking is a technique for simulating the behavior of a function or object to test its interactions with other components ConclusionIn conclusion automated testing is an essential part of software development and Python s unittest framework provides a powerful tool for writing and running tests By using this framework developers can ensure that their code meets its requirements functions as expected and does not introduce bugs or regressions	2023-02-22 17:25:26

latest Lerna news and newest features Table of ContentsLerna Brought to You by NxStill On Lerna Idempotency Added to the lerna publish from git CommandNew include private Option Added To lerna publishlerna run Can Run Multiple Scripts In a Single CommandMassive RefactorGetting Started With Lerna From The Lerna TeamThe Future of Lerna Lerna Brought to You by Nx In case you missed it Lerna the OG JavaScript monorepo tool went largely unmaintained for a while starting around Then it officially declared itself to be unmaintained in April of only for Nx to step in to take over maintenance of the project in May of You can find a more detailed account of Lerna s Maintainance Odyssey in this article Since Nx took over in Lerna we ve added a brand new site to refresh the Lerna Docs The top of our priorities for Lerna was to resolve all vulnerabilities and outdated dependencies facing Lerna We went on to make Lerna faster by allowing users to opt into Nx s task caching inside of Lerna with the new lerna add caching command and add support for distributed caching to share task results amongst your organization in Lerna with Nx Cloud We were proud to go on to launch Lerna last October where we began focusing on further improving Lerna s feature set focusing specifically on its unique strengths versioning and publishing Still on Lerna Here s how to upgrade to the latest and greatest We ve also started an initiative to assist Open Source projects in getting the most out of Lerna Projects that use Lerna can now request free consulting to learn how to take advantage of Lerna s newest features We ve just started this initiative and have already been able to help Sentry get optimized with task caching and task pipeline optimizations for their workspace This initiative complements our free tier of unlimited Nx Cloud for any Open Source project If you re interested in optimizing your Open Source project to take advantage of the latest Lerna features reach out to us on Twitter Now let s jump into the newest Lerna features Idempotency Added to the lerna publish from git Command Idempotent is a word used to describe an operation you can perform any number of times and the resulting state is the same as if you had only run the operation once The lerna publish command is a beneficial tool for quickly publishing multiple packages from your workspace Running lerna publish by itself will version and publish all packages in the workspace since your latest releaseRunning lerna publish from git will publish all projects tagged in the latest commitRunning lerna publish from package will publish all projects whose version does not yet exist in the target registry based on the version listed in their package json file As we can see lerna publish from package is already idempotent since it only publishes packages whose version doesn t exist any run past the first will not adjust the state of the registry With we ve added the same idempotency to lerna publish from git This update is handy for recovering from a situation where some of your packages failed to publish initially maybe due to a networking issue For more information check out the PR New include private Option Added To lerna publish Npm supports a private true configuration as a way of preventing the publication of a library that is private gt lerna publish from git include private my private packageRunning lerna publish with this new include private option as above will strip this private true configuration from the package json of the packages listed in the command This new option is beneficial for the use case where you d like to run ee for a package that will eventually be public but is currently private to prevent getting published too soon You can find more information on this change here lerna run Can Run Multiple Scripts In a Single Command For we ve added the ability to run multiple scripts in a single lerna run command Checkout this quick video demonstrating this below Learn more here Massive Refactor Unlike the other updates mentioned for this update does not affect Lerna s public API but as you can see from the numbers this was quite an undertaking The result is a significant improvement to the Typescript support for Lerna s internals and a substantial simplification of the codebase This investment will make Lerna significantly more approachable to other would be contributors Find more on this change here Getting Started With Lerna From The Lerna Team We recently ran a live stream with James Henry and Austin Fahsl from our Lerna team to show how to get started with Lerna all the way through to versioning and publishing our packages to npm Check out the recap of this session above and check out the repo from our session on

GCP	Cloud Blog	No cash to tip? No problem. How TackPay built its digital tipping platform on Google Cloud	https://cloud.google.com/blog/topics/startups/tackpay-builds-digital-tipping-platform-on-google-cloud/	No cash to tip No problem How TackPay built its digital tipping platform on Google CloudSociety is going cashless While convenient for consumers that s caused a drastic decrease in income for tipped workers and this is the problem TackPay addresses TackPay is a mobile platform that allows users to send receive and manage tips in a completely digital way providing tipped workers with a virtual tip jar that makes it easy for them to receive cashless tips directly Digitizing the tipping process not only allows individuals to receive tips without cash but also streamlines a process that has frequently been unfair inefficient and opaque especially in restaurants and hotels Through TackPay s algorithm venues can define the rules of distribution and automate the tip management process saving them time And because tips no longer go through a company s books but through Tackpay it simplifies companies tax accounting too With a simple fast and web based experience accessible by QR code customers can leave a cashless tip with total flexibility and transparency Technology in TackPayWithout question our main competitor is cash From the very beginning TackPay has worked to make the tipping experience as easy and as fast as giving a cash tip For this reason the underlying technology has to deliver the highest level of performance to ensure customer satisfaction and increase their tipping potential For example we need to be able to calibrate the loading of requests in countries at peak times to avoid congesting requests Offering the page in a few thousandths of a second allows us to avoid a high dropout rate and user frustration Transactions can also take place in remote locations with little signal so it is crucial for the business to offer a powerful and accessible service for offline availability options These are a few of the reasons TackPay chose Google Cloud Functional componentsTackPay interfaces include a website web application and a mobile app The website is mostly informational containing sign up login and forms for mailing list subscription and partnerships The web app is the application s functional interface itself It has four different user experiences based on the user s persona partner tipper tipped and group The partner persona has a customized web dashboard The tipper sees the tipping page the application s core functionality It is designed to provide a light weight and low latency transaction to encourage the tipper to tip more efficiently and frequently The tipped i e the receiver can use the application to onboard into the system their tip fund and track their transactions via a dashboard The group persona allows the user to combine tips for multiple tip receivers across several services as an entity  The mobile interface also has similar experience to that of the web for the tipped and group personas A user dashboard that spans across a few personas covers the feedback wallet transactions network profile settings bank details withdrawal docs features for the Tipped persona In addition to those features the dashboard also covers the venue details for the Group persona Technical architecture to enable cashless tippingBelow is the technical architecture diagram at a high level IngestionData comes in from the web application mobile app third party finance application APIs and Google Analytics The web application and mobile app perform the core business functionality The website and Google Analytics serve as the entry point for business analytics and marketing data  ApplicationThe web application and mobile app provide the platform s core functionality and share the same database ーCloud Firestore The tipper persona typically is not required to install the mobile app they interact with the web application that can be scanned via a QR code and tip for the service Mobile app is mainly for the tipped and the group categories  Some important functional triggers are also enabled between the database and application using Google Cloud Functions Gen The application also uses Firebase Authentication Cloud IAM and Logging Database and storageFirestore collections are used to hold functional data The collections include payments data for businesses teams the tipped tippers and data for users partners feedback social etc BigQuery stores and processes all Google Analytics and website data while Cloud Storage for Firebase stores and serves user data generated from the app  Analytics and MLWe use BigQuery data for analytics and Vertex AI AutoML for Machine Learning At this stage we re using Data Studio for on demand self serve reporting analysis and data mashups across the data sets The goal is to eventually integrate it with Google Cloud s Looker in order to bring in the semantic layer and standardize on a single point of data access layer for all analytics in TackPay  Building towards a future of digital tippingTackPay product has been online for a few months and is actively processing tips in many countries including Italy Hungary UK Spain Canada The solution has been recently installed in leading companies in the hospitality industry in Europe becoming a reliable partner for them There is an ambitious plan to expand into the Middle East market in the coming months  To enable this expansion we ll need to validate product engagement in specific target countries and scale up by growing the team and the product Our technical collaboration with Google Cloud will help to make that scaling process effortless If you are interested about tech considerations for startups fundamentals of database design
