海外TECH	DEV Community	How to Setup a Node API with SWC Compiler and ESLint	https://dev.to/franciscomendes10866/how-to-setup-a-node-api-with-swc-and-eslint-1h5d	How to Setup a Node API with SWC Compiler and ESLintAs our APIs get a larger code base consequently the time it takes to build and even hot reload will be longer By the way who ever made a small change and then had to wait almost three seconds for the API to hot reload Or even making several changes in a short amount of time and then having problems with the process running This is where compilers like SWC help us whether during the development of our applications or during the compilation and bundling process In today s article we are going to setup an API in TypeScript and then we will proceed to configure the SWC together with ESLint During the development of the application we will want the SWC to watch the changes we make to our TypeScript source code as soon as it has any changes it will transpile to JavaScript from the same file we made the changes Finally we will use nodemon to watch the changes that occur in the transpiled code and we will hot reload the API as soon as there is a change What is the advantage during the development of our API Most of the articles I read use nodemon to watch the code and as soon as there is a change they build the entire API Even if SWC is fast it s always good to have good approaches When we need to put the API into production just do the regular process just run the build command and then we would have to run the start command Project SetupFirst let s start with the usual one which is to create the project folder mkdir swc configcd swc configNext initialize a TypeScript project and add the necessary dependencies npm init ynpm install D typescript types nodeNext create a tsconfig json file and add the following configuration to it compilerOptions target es module es allowJs true removeComments true resolveJsonModule true typeRoots node modules types sourceMap true outDir dist strict true lib es baseUrl forceConsistentCasingInFileNames true esModuleInterop true experimentalDecorators true emitDecoratorMetadata true moduleResolution Node skipLibCheck true paths routes src routes middlewares src middlewares include src exclude node modules As you may have noticed we already defined some things in our tsconfig json that I don t usually define in my articles such as creating a path alias and using a very current version of ES With the configuration of our project in TypeScript we can now install the necessary dependencies In this project I will use the Koa framework however this setup works with many others such as Express Fastify etc dependenciesnpm install koa koa router koa body dev dependenciesnpm install D types koa types koa routerNow with these base dependencies we can create a simple api starting with the entry file src main tsimport Koa from koa import koaBody from koa body import router from routes index const startServer async Promise lt Koa gt gt const app new Koa app use koaBody app use router routes return app startServer then app gt app listen catch console error Then we can create our routes src routes index tsimport KoaRouter from koa router import Context from koa import logger from middlewares index const router new KoaRouter router get logger ctx Context void gt ctx body message Hello World export default routerAnd a simple middleware src routes index tsimport Context Next from koa export const logger async ctx Context next Next Promise lt Next gt gt const start Date now const ms Date now start console log ctx method ctx url ms ms return await next With this we can now move on to the next step which will be the SWC configuration SWC SetupNow we can install the necessary dependencies to configure our SWC npm install D swc cli swc core chokidar nodemon concurrentlyNext let s create a swcrc file and add the following configuration to it jsc parser syntax typescript tsx false decorators true dynamicImport true target es paths routes src routes middlewares src middlewares baseUrl module type commonjs Now let s add the necessary scripts to our package json scripts dev concurrently npm run watch compile npm run watch dev watch compile swc src w out dir dist watch dev nodemon watch dist e js dist main js build swc src d dist start NODE ENV production node dist main js clean rm rf dist In the watch compile script swc will automatically transpile the code using chokidar While the watch dev script uses nodemon to hot reload the application When the dev script is executed concurrently executes both commands watch compile and watch dev at the same time so that swc transpiles the TypeScript code to JavaScript and nodemon hot reloads the API when notices a change With the SWC configured we can move on to the ESLint configuration ESLint SetupFirst we will install ESLint as a development dependency npm install D eslintThen we will initialize the eslint configuration by running the following command npx eslint initThen in the terminal just make the following choices Now we can go back to our package json and add the following scripts scripts lint eslint ext ts src lint fix eslint ext ts src fix Finally just create the eslintignore file and add the following dist ConclusionI hope you enjoyed today s article and that it was useful to you even if it is to try something new Finally I leave here the link of a repository in which I have a similar configuration but using Express See you	2022-04-10 13:20:35

海外TECH	DEV Community	When the Captain Turns the Helm: a 7 Steps Migration	https://dev.to/otomato_io/when-the-captain-turns-the-helm-a-7-steps-migration-10cc	When the Captain Turns the Helm a Steps MigrationShall we continue with sea allegories I made an amazing picture to attract attention Large organizations are often quite conservative when it comes to upgrading to the latest software versions Of course it is very important to be sure that everything works clearly and correctly especially considering Helm s wide use in CI Fear of migration is not so unfounded We re not sailors onboard the RMS Titanic who didn t have binoculars are we You should turn the helm understanding which way the ship will turn But first things first Helm v became legacy in late but there are companies that still use version in their practices these days There are not many short and clear summaries on the Internet about migrating to Helm v Well in this note the author will try to break everything down into points Stage BackupBackup all the existing releases It s important to take a backup of all the releases before starting with the migration Though the first step of migration won t delete Helm v s release information it s always better to take a backup By default Helm v stores its releases data as ConfigMaps in kube system namespace of the cluster This command is to list Helm v releases kubectl get configmap n kube system l OWNER TILLER Helm v changed the default release information storage to Secrets in the namespace of the release How to list Helm v releases kubectl get secret namespace my namespace grep sh helm releaseUsing helm backup plugin by Maor maorfr Friedman The helm backup is a Helm v plugin which can take backup of releases and also has the ability to restore them Here is how it achieves the backup It finds the storage method used by Tiller then backs up the ConfigMaps along with release names as a tar file While doing the restore it first applies the ConfigMaps Then it tries to find the release with STATUS DEPLOYED label gets the manifest YAML for that release and then applies it Another way is to just backup all the ConfigMaps which hold the release information The easiest way to do it is to run the following command kubectl get configmaps namespace kube system selector OWNER TILLER output yaml gt helm backup cm yaml Stage Converting releasesWhen we install or update a chart it creates one Helm release in the cluster It is stored as a ConfigMap within the cluster in case of Helm v This makes it possible to do the rollback and keeps a history The format in which Helm v stores the release information is different from v v uses Secrets predominately as a storage The to plugin written by Martin Hickey will do the work of converting these releases to the new format ️An important note about access to the tiller namespace for required RBAC roles If Tillerless setup then a service account with the proper cluster wide RBAC roles will need to be used If not used forbidden errors will be thrown when trying to access restricted resources Install to plugin helm plugin install Stage Dumping Helm v Tiller releases It is good to have this list for your confidence helm tiller run helm ls max sed n p awk FNR gt print gt releases log kubectl n kube system get configmap l OWNER TILLER STATUS DEPLOYED awk FNR gt print cut f d gt releases log Stage Launching an automated migration with a bash script bin bashhelm cmd helm if x which helm gt dev null then helm releases helm ls all short else echo helm is not installed or not present in PATH Using kubectl to get list of releases …fiecho e Found the following releases n helm releases n for release in helm releases do helm cmd to convert dry run release read p Convert release Y n user choice if user choice Y then echo Converting release helm cmd to convert release echo Converted release successfully else echo Skipping conversion of release fidoneThe original script written by Bhavin Gandhi Stage Resolving Kubernetes API validation problemHelm v validates all of your rendered templates against the Kubernetes OpenAPI schema This approach supposes your rendered templates are validated before they are sent to the Kubernetes API That means any invalid fields will trigger a non zero exit code and fail the release Lack of fields will lead to the same The labels and annotations which had not been added to migrated Kubernetes objects should be added manually kubectl n NAMESPACE label deployment l app kubernetes io instance RELEASE app kubernetes io managed by Helm kubectl n NAMESPACE annotate deployment l app kubernetes io instance RELEASE meta helm sh release name RELEASE meta helm sh release namespace NAMESPACE ️Example of needed labels amp annotations which are valid for stage metadata labels app kubernetes io instance Release Name app kubernetes io managed by Helm annotations meta helm sh release name Release Name meta helm sh release namespace Release Namespace If before we relied entirely on the version of Helm then we have Tiller installed in our cluster so we may omit tiller out cluster flag The safest way of course to start with dry run flag for simulation only Stage Checking out whether it was successfulHelm v now behaves similarly to kubectl With Helm v you could query all releases across all namespaces simply by typing helm ls With Helm v running helm list will only show releases in the default namespace just like kubectl get pods would To list releases in any non default namespace you must supply the n argument and the namespace just as you would when using kubectl helm list n lt namespace gt Stage Helm v cleanupAs we did not specify delete v releases flag Helm v releases information was left in tact it can be deleted with helm to cleanup later on Stage Bye bye TillerAfter all we may remove Tiller from our cluster kubectl delete deployment tiller deploy namespace kube system Note A Check your CIs CLI commands renamedSome CLI commands have been renamed in Helm vhelm delete is renamed to helm uninstall but the first one is still retained as an alias to helm uninstall Also in Helm v the purge flag removes the release configs In Helm v this feature is enabled by default To retain the previous behavior you can use the command helm uninstall keep history helm inspect command is renamed to helm show helm fetch command is renamed to helm pull Note B Check your YAMLsWhen chart s Kubernetes apiVersion is set to v it signifies that it is using v schema that is introduced in Helm v Therefore apiVersion v is not rendered in Helm v because of this If you need more compatibility stay on v here Please see my post on LinkedIn for references Pic source Padok Painless migration to you Happy

am assuming that you are a complete beginner in Python So I will start the learning path from scratch For our convenience I have divided the whole learning path into different steps So that we can easily move forward step by step and achieve your learning goal I will also mention the resources to learn the different topics of Python So this article is a complete guide for your learning But before starting the learning path I would like to discuss why Python is good for Data Science I know you already knew this…that s why I will not bore you with so much detailed explanation I will only explain why I like Python for Data Science Why Python is Good for Data Science The most appealing quality of Python is that anyone who wants to learn it even beginners can do so quickly and easily Unlike other programming languages such as R Python excels when it comes to scalability And the most important thing is that Python has a wide variety of data analysis and data science libraries pandas NumPy SciPy StatsModels and scikit learn Python also has a huge community That means there is a huge Python community that can help you when you are stuck at some point So these are the main reasons I prefer Python for data science Now let s move to your question “What Should I Learn in Python for Data Science and start with the first step Step Learn Python BasicsYou have to start with learning Python Basics when I say “Python Basics …you might be thinking about what exact topics you have to learn Right So don t worry…I am going to list the topics which you have to learn in this step So that you will not be confused about topics In Python Basics learn the following topics Installing Python amp Python EnvironmentNumbersStringsListStandard Input OutputBasic commands in PythonIf

Avinash Jain Step Learn Python Libraries for Data SciencePython has a rich set of libraries to perform data science tasks At this step you have to learn about these libraries Libraries are the collection of pre existing functions and objects You can import these libraries into your script to save time If you want to know the differnce between Differences Between Python Modules Packages Libraries and Frameworks click the link belowDifferences Between Python Modules Packages Libraries and FrameworksPython has the following libraries Numpy NumPy will help you to perform numerical operations on data With the help of NumPy you can convert any kind of data into numbers Sometimes data is not in a numeric form so we need to use NumPy to convert data into numbers Pandas pandas is an open source data analysis and manipulation tool With the help of pandas you can work with data frames Dataframes are nothing but similar to Excel files Matplotlib Matplotlib allows you to draw a graph and charts of your findings Sometimes it s difficult to understand the result in tabular form That s why converting the results into a graph is important And for that Matplotlib will help you Scikit Learn Scikit Learn is one of the most popular Machine Learning Libraries in Python Scikit Learn has various machine learning algorithms and modules for pre processing cross validation etc So these are
