海外TECH	DEV Community	The #1 tip to familiarize with new JavaScript codebases	https://dev.to/igeligel/the-1-tip-to-familiarize-with-new-javascript-codebases-2m1	The tip to familiarize with new JavaScript codebases The tip to familiarize with new JavaScript CodebasesIn my years as a software engineer I have probably looked at hundreds of codebases Too many to count I struggled a lot with understanding where the relevant code is most of the time Normally asking for help what I should look for and guidance in tickets will bring me forward Slowly and surely I will understand what the code is doing And you will too Some people are better at this and some people will be slow No shame Most code is complex But I found a simple tool that will make it easier for you It is called code complexity and you can use it as the following code snippet shows npx code complexity limit sort ratio You can also use filter js to use glob patterns to filter filesIt will return an output like the following filecomplexitychurnratiosrc cli tstest code complexity test ts idea workspace xmlThis will show the biggest and most changed files The likelihood that these files are crucial for understanding the application is quite high Read through them and understand them What this data means in detail will be explained in this blog article now Complexity and ChurnIn this chapter I will explain to you the concepts of complexity and churn when it comes to code It is the baseline to understand the technique we are using here to improve your understanding of a codebase What is Complexity Complexity can be defined in different ways The level of nesting of functions is normally used as a measurement of how complex code is Code with small functions and composed behavior is normally more readable and easy to understand So we could say that complex code also consists of a few functions that are far nested and it is mostly true Nesting is hard to track though so we could find another metric somehow With long functions normally there comes large files as well People tend to put everything into one file if they also put a lot into one function So in theory we could take the lines of code as a measurement as well There are a lot of utility packages out there that solve this problem One of these tools is called sloc It will output the number of lines of code within a file But do not use it directly The tool I mentioned before includes this by default So in conclusion we can say complex files are either super nested or super long One of these things normally comes with the other so that s great to hear because analyzing the length of a file tends to be easier than nesting What is Churn Churn is a bit more complicated to explain But let us start somewhere A churned file is a file that has a lot of changes But what does this mean A lot of changes to a file happens when yeah a lot of people have changed the file But how can someone measure that The git history is telling us how often a file was checked in So we can make sure with that how likely a file is to be changed Normally this means files of this type are the main point of the application A problem that occurs though is that often there are configuration files included here but you can simply exclude them for this analysis What can Complexity Churn teach us Now after learning what complexity and churn mean we can focus on the combination of them Files that normally charge a lot but are also really complex should be normally refactored And most of the time with that it is natural that these files might be the core of the application The basic logic is written in them directly or in files related to that So let us check how we can analyze that further Checking the files in detailMy technique to check the files in detail is quite simple I first look over the file and check what the exported functions are called Ideally I write them down Internal functions are firstly not important to understand Once I have an overview of all the exported functions I foremost check if there are any unit tests If the functions have parameters as well then I will try to write them down as well With TypeScript or Flow types this gets even more easier to get an overall feeling of the structure Unit tests are a good first approach to see how the functions are working To understand functions you probably just need to look at the input the function name and what it is returning In most of the cases types even support you with that and unit tests will show you edge cases for the function and how it can be used So that s mostly enough to understand the function At least if you know the programming language If you want to get deeper into the function feel free to but you do not have to do that Why Explained in the next chapter Why do not understand every detail Understanding a function in detail can be important But during onboarding a lot of other things are more important You will not be able to understand every bit of the application within a short time frame but understanding the core parts should give you a track of where the core logic of the application is executed With that knowledge you can jump into the first issues for you Ideally the team has prepared smaller tasks in the codebase to give you a nice onboarding experience If that is not the case ask your manager or senior engineers in your team if any of the current issues is suitable for you Make sure to transmit your gained knowledge of the codebase though so they understand your knowledge level A good idea for the first issue is also to do pair programming with other software engineers from the team Make sure to tell them that you want to type mostly and they should be more of supervisors so you learn how to navigate the codebase by yourself Because of that guided onboarding or easier tickets you do not have to jump into details The details of the code will be discovered now during the implementation phase of fixing bugs or adding features The more tickets you will do the more you learn about the codebase in detail But look back at churn and complexity because it can change over time Debugging the details Having to work on the code base now will also involve another bigger thing Debugging With your first tasks you will probably learn already how to run the application locally run unit tests and integration or EE tests if these exist These become vital once you implement the feature because adding tests will make sure your application is working as expected Often these tests cover a lot of code though and are kind of abstract In these cases you have to learn to debug your code Because most of the tests are being run in a Node js environment we will have a quick peek into how to debug Node js based applications Most engineers use console log to debug and it is completely valid But if you need to follow larger structures of code I can recommend using a proper debugger JavaScript and TypeScript support the debugger keyword nevertheless it is a bit tricky to run your test suite and have a nice debugger experience because within Node js it is a bit difficult to spawn a browser instance s developer tools and connect it to the program Another option would be to use your IDE or Editor to connect a debugger supported by your coding user interface For example Visual Studio Code supports debugging Node js applications directly in the IDE A guide on how Node js debugging in VS Code can be found here Debugging is an art in itself You should get comfortable using breakpoints and what the debugging functions step over and step into mean These will be extremely helpful when debugging nested functions Some examplesIn this chapter I will go through some codebases with this technique to explain where the main core of the application is and how the process mentioned above can help you to get familiar with the code base quicker Blitz jsBlitz js is a framework built on top of Next js It describes itself as the Ruby on Rails for JavaScript TypeScript The team is working for more than a year on this framework and it would be quite interesting to see where the core of their logic is being placed The first step of course is to clone the repository to a local folder and then run npx code complexity limit sort ratioThis will output the following table filecomplexitychurnrationextjs packages next compiled webpack bundle jsnextjs packages next compiled webpack bundle jsnextjs packages next compiled webpack bundle jspackages

index tsxpackages display src index tsAs you can see there are a lot of unrelated files that could be filtered out like the compiled folder but for an initial analysis this is enough We can see multiple directories being important here packages clipackages generatorpackages serverpackages coreIf we get a task we would at least know already where to look for related code Initially I would try to understand the packages core files to understand what they are doing Understand the tests if they exist and then you should have a good grasp of what Blitz is doing React jsReact js is a frontend framework that almost every web developer knows by now What most people do not know is how the codebase is structured and what are the core parts So let us have a look at it npx code complexity limit

and how react dom s partial renderer is working will give you a good idea about React s architecture A good thing about the code within React is that it is well documented with comments even though it is complex at first Venom A TypeScript Client for WhatsappVenom is a library to interact with Whatsapp You can send messages via this library and do many more things It is a bit more practical because on such applications you will work mostly in your day to day job So let us run our usual command npx code complexity limit sort ratiofilecomplexitychurnratiosrc lib jsQR jsQR jssrc lib wapi wapi jssrc

files We can see that src api layers sender layer ts and src api layers retriever layer ts are not complex but have a lot of changes So every time a feature is added or deleted these files are touched These are the core files of the application and understanding them will give you a good grasp of how the codebase is structured and what you should focus on Where does this technique come from This technique of analyzing a codebase originally came from a book that handles refactoring large codebases via a process Software Design X Rays by Adam Tornhill It is a great book and teaches you a lot of ways to structure your code and what parts are worth refactoring A great book I think every software engineer should have read it at some point because it will help them to understand a codebase differently With working on a project people will get familiar with different parts of the software and of course they will have their special area of code where they are super comfortable If this code is good and understandable is another question though that this book tries to answer Based on the refactoring efforts we can also use the knowledge to see which parts of the application are important Hopefully I explained this in this blog article to you Other LanguagesThe tool code complexity is closely coupled to JavaScript and TypeScript based codebases For other languages like Java C Python or PHP there are other tools but one tool that is generic and works for most of the codebases is code maat It is a tool created by the author of the book mentioned in the chapter before With that you can analyze a software project as well and come to the same conclusions as mentioned in the blog article ConclusionI hope you liked this article and made your life a bit easier Coming to a new code base is difficult and especially with the ever changing JavaScript world it is difficult to follow With the tools and processes presented in this article you might have an easier time actually fit well into a new codebase Feel free to share this article with your workers and also tell them about the techniques you are using Most of the developers I know do not know about the churn and complexity analysis and it might be really helpful for everyone So share it	2021-05-28 09:04:06

GCP	Cloud Blog	Diversity in leadership: Celebrating the success of Asian & Pacific American founders with Google Cloud	https://cloud.google.com/blog/topics/startups/diversity-leadership-celebrating-success-asian-pacific-american-founders-google-cloud/	Diversity in leadership Celebrating the success of Asian amp Pacific American founders with Google CloudMay is Asian Pacific American Heritage Month ーa time for us to come together to celebrate and remember the important people and history of Asian and Pacific Island heritage This feature highlights three AAPI founders from the Google For Startups community Read on to learn how these three founders built their businesses leverage Google tech and suggestion they have for aspiring entrepreneurs CultivatePeople Founder Lola HanDescription CultivatePeople s compensation software Kamsa provides global market pay rate data and helps companies make data driven salary decisions so they can attract and retain their most valuable asset employees  Why GCP “CultivatePeople began using GCP when integrating SSO SAML authentication after our SaaS product became a high priority We were able to exceed our clients expectations and increase their level of trust in our platform s capabilities We re currently investigating additional machine learning products such as Cloud AutoML that will allow us to quickly deliver exciting features  Note from the Founder “I grew up with immigrant parents who value stability and are risk averse My parents discouraged me from starting my own company because they didn t want to see me struggle financially or see my health suffer due to stress I felt strongly about what CultivatePeople could do so I started the company as a sole founder in and watched it double in size year over year since While the ones I love most may not have cheered me on initially it was important for me to hang on to the encouraging words of former bosses executives and founders to keep me focused on my mission  My advice for other AAPI founders is to be a silent assassin and believe in the mission and values of your organization Always remember to stop along the way and    Enjoy the journey by celebrating wins and giving yourself credit Follow your intuitionーit s almost always right   Recognize and invest in your people regularly ie give increases more than once a year if warranted Give regular words of affirmation to employees on even small achievements SwitFounder Josh Lee and Max LimDescription Swit is a team collaboration platform that seamlessly combines team chat with task management by allowing teams to turn their conversations into trackable tasks and share tasks to chat with simple drag and drop functionality ensuring everyone is on the same page and projects get done faster Why GCP “Swit is a cross category hybrid work tool for chat and tasks This functionality requires more complicated and heavier architecture for performance So configuring and managing virtual machines was really challenging to scale up our systems while handling occasional unexpected traffic surges and frequent updates Eventually we divided our monolithic architecture into microserviceswhen we launched our official product The migration to GKE took around one month and it turned out to be well worth the effortーour systems became able to offer high scalability and enough resilience to keep its uptime no matter what happened Now we re operating workloads and microservices with high stability with remarkably low downtime less than year Note from the Founder “As an AAPI founder based in Silicon Valley I feel proud of the work ethics and diligence fellow Korean American entrepreneurs and professionals have long demonstrated here Especially with K pop breaking into the mainstream I feel even more proud of our culture that strives toward an absolute perfection molded through years of training and dedication The mission driven culture of Silicon Valley coupled with Google s edging technology and creativity really helped us build a product that not only encompasses verticals but also transcends cultures Swit is growing at an unprecedented rate and we hope to join the long list of successful AAPI entrepreneurs here Swit s close network with the AAPI community wouldn t have been possible without Google support We are grateful for this collaborative environment and we hope to become the next generation ambassador for collaboration after Google  Check out more from Swit in their founder story WISY Founder Min ChenDescription Wisy develops technology to bring digital efficiency into the physical world supporting consumer products businesses and making them thrive in the new economy All of us have a bad experience when we can t find the product we want to buy That is a T problem in the consumer packaged goods industry that Wisy is solving with AI and analytics to help manufacturers and retailers sell more by reducing out of stocks and waste at a global scale Why GCP “GCP has an intuitive easy to use interface was lower cost and offered preemptible instances with flexible compute options Some of the reasons why Wisy decided to use GCP include instance and payment configurability privacy and traffic security cost efficiency and Machine Learning Wisy has been able to advance quickly with product development as well as collaborate better and iterate faster in the creation of our AI models while reducing costs by At Wisy we are solving a problem that affects everyone who shops at a store “Note from the Founder “Two years ago I moved to San Francisco to expand my second startup Wisy This is when I learned that my name Min stands for minority I was born in China raised in a Black community in Panama received scholarships to attend both Carnegie Mellon and UC Berkeley I worked for years in several countries but I have never felt so discriminated against due to my race ethnicity gender and age than during my time in Silicon Valley However this is also the place I learned that my diverse life experience is my competitive advantage My background enables me to recruit and relate to people in different countries create scalable and flexible products for multinational customers and run global operations efficiently My recommendation to AAPI founders is to find strength in their multicultural background Don t hide what makes you unique do not limit yourselves and do not let others limit you You will lose your edge when trading authenticity for validation Be proud and own your
