海外TECH	DEV Community	Optimizing Lambda Performance for Your Serverless Applications	https://dev.to/tlakomy/optimizing-lambda-performance-for-your-serverless-applications-44lo	Optimizing Lambda Performance for Your Serverless Applications Lambda overviewLooking at the anatomy of a lambda function we can identify several different layers Your functionLanguage runtimeExecution environmentLambda service invisible to customers managed by AWS Compute substrate invisible to customers managed by AWS Apart from well known Lambda runtimes Node js Go etc Lambda also supports custom runtimes that you can bring in to Lambda service so it s possible to use languages like Perl Erlang and even COBOL Lambda itself is agnostic to your choice of runtime and has no preferences for one runtime over another Out of layers mentioned earlier there are only three where our decisions make a difference function itself execution environment and Lambda service It s worth mentioning that AWS is consistently improving the performance of invisible layers as well Quick recap of anatomy of an AWS Lambda function Handler function a function to be executed upon invocationEvent object data sent during Lambda function invocationContext object methods available to interact with runtime information request ID log group etc There s a difference between a full cold start e g whenever a function is run for the very first time and a partial cold start when the execution environment is already running since it stays around for a while The first two steps downloading the code and starting a new execution environment are optimized by AWS whereas the last two can be optimized by a developer AWS X Ray allows us to identify areas for performance optimization X Ray can both be enabled as an Active tracing checkbox in Lambda console or via the aws xray sdk core Optimizing Lambda Three areas of performanceLatencyThroughputCost Latency cold startsA Lambda function call always starts with a request to Lambda s API The next steps depend on whether there is a warm execution environment available If there is one that means that the Lambda function was executed rather recently and the handler can be invoked on that execution environment This becomes a bit more complicated if a warm execution environment is not available The INIT code is referring to code that is defined outside of the handler function Cold starts affect less than of production workloads they are much more common in development environments since there is way less traffic A duration of a cold start varies from less than ms to more than s It s not possible to target warm environments The only actual guarantee of getting a warm environment is using provisioned concurrency pinging functions to keep the warm will not work when function is scaling out or the execution environment is being load balanced to a different AZ Making function packages as small as possible helps since there s simply less code to download Generally speaking functions executed more often than others will be hitting warm environments more frequently Static initialization is influenced by size of function packageamount of codeamount of initialization work that is code that runs before the handler function The developer is responsible for this part of a cold startWhat can help Trimming SDKs reusing DB connections not loading things we don t need and lazy loading If you absolutely need to have warm execution environments use Provisioned Concurrency on AWS Lambda announced at Re Invent Provisioned concurrency has a rampup of execution environments per minute so if you need k execution environments it ll take minutes to spin them up It s possible to have different provisioned concurrency for different versions of the Lambda function and remember that it s not possible to use provisioned concurrency for LATEST version Memory and profilingLambda exposes only memory control as it s not possible to modify anything else that influences the power of a Lambda function The default is MB which is well suited for small Lambda functions but its definitely possible to save money time by assigning a larger memory for your function AWS Lambda Power Tuning allows the developer to optimize their lambda function from cost performance perspective without running manual experiments Architecture and best practicesAvoid monolithic functions optimize package size micro nano services Minifiy uglify production codeOptimize dependencies and importsLazy initialization of shared libraries objectsIt s better to have a lambda function per purpose rather than one giant Lambda that is essentially yourBusinessLogic js In order to solve issues with connections to a relational database consider using an RDS Proxy RDS Proxy launched at Re Invent will intelligently manage your connections to a relational database in RDS As such it helps match the way that scalable compute works with traditional database architectures In order to reuse existing connections and improve the performance of functions using http s request use keep alive property in order to reuse TCP connections on warm execution

than React Solid is reactive and directly updates the DOM without virtual DOM The render function is only called once even if the state changes and there are no stale closure issues A good article to discover the differences between these frameworks and discover Solid I find Solid really interesting In the short term it can be a very good alternative to React for web apps However I am waiting to see the practical use of the innovations of React because I think that the virtual DOM is interesting for the highly anticipated concurrent features Headless components in React and why I stopped

海外TECH	DEV Community	How to add chat into a NodeJS app with TalkJS	https://dev.to/talkjs/how-to-add-chat-into-a-nodejs-app-with-talkjs-53n	How to add chat into a NodeJS app with TalkJSThis article is another entry in our series about integrating the TalkJS chat API with different backends Today it is all about shipping a full fledged chat feature for any NodeJS app Similar to the previous articles you can find here we set up a NodeJS server that consists of specific endpoints to get user data as well as store user data and then use this to initialize a chat The chat uses the same data as the previous articles so it is very easy to relate The entire source code is always available on GitHub NOTE This is a barebones example of integration and is to help you get started When using in a production setting ensure that users are authenticated and authorized to use the services We are using an embedded database which is only for the scope of this tutorial For production scenarios you must use a full fledged database Installing the dependenciesTo create an empty npm project use the command npm init y The argument y sets defaults for the parameters inside package json Once created you can start downloading the dependencies Make sure you add the parameter type module inside the package json file to use ES style import statements We have dependencies that we need for this demo project They are cors body parser express lowdb Express is our go to choice for creating APIs with NodeJS and body parser automatically parses your request so that it becomes easy to handle them in our code LowDB is an embedded database similar to the ones we used in our Spring Boot and Flask tutorials but here it is stored in a JSON file CORS is to enable cross origin resource sharing import express from express import cors from cors import bodyParser from body parser import LowSync JSONFileSync from lowdb After installing them create a file called server js and import them into the application LowDB Easy to use embedded database for JavaScriptLowDB is an open source embedded database for JavaScript and their GitHub page has very comprehensive documentation on how to get started with examples const adapter new JSONFileSync file json const db new LowSync adapter db read db data users To create a simple JSON database we use the JSONFileSync function and pass in the required filename If it is not present LowDB creates it for you We then pass that to the LowSync method to get an instance of the database in memory Note that the Sync in the functions means synchronous There are also asynchronous variants of these functions By default we create an empty array of users inside the database Creating the APIsBefore creating the APIs we must initialize our Express application and configure body parser For that we use the below code const app express const port app use cors app use bodyParser urlencoded extended false app use bodyParser json Once that is set we are good to start creating our APIs As usual we have one API for creating the user and one for getting the user data to our frontend Create User APICreating a user is a POST request We receive all the parameters from the request body and set it to variables To make it shorter we can directly assign them when we push it to the database as well app post createUser req res gt const id req body id const name req body name const email req body email const photoUrl req body photoUrl const role req body role console log id name email photoUrl role db data users push id id name name email email photoUrl photoUrl role role db write res status send User created successfully Once all the data is ready we use the statement db data users push and pass in an object with the values This does not persist in the file so we finally need to use the db write method Get User APIThis is a much easier API to get the value of the user We pass in the id in the URL and then retrieve the record from our JSON file with the id We use the find method and pass in an arrow function to go through each entry and retrieve the record app get getUser id req res gt const id req params id let record db data users find p gt p id id if record console log No data found else console log Record found console log record res status send record Once retrieved we send the record to the frontend where it displays the user information in the chat ConclusionWe use the same code as we did for the previous articles for the front end The only change required is for the getUser API that needs the userId in the following format getUser instead of getUser id Once you make that change and deploy the frontend it should pull the information from the server as long as the data is present To add data you can use the createUser API You can check out the entire source code at GitHub Until the next tutorial happy coding	2022-03-09 09:02:43
海外TECH	DEV Community	GraphQL subscriptions at scale with NATS	https://dev.to/karanpratapsingh/graphql-subscriptions-at-scale-with-nats-f19	GraphQL subscriptions at scale with NATS GraphQL subscriptions at scale with NATSIn this article we ll look at how to setup GraphQL subscriptions at scale with NATS Note If you re not familiar with NATS please checkout my earlier article Why GraphQL subscriptions In my opinion subscriptions are quite underrated and often overlooked They provide just the right amount of abscraction over websockets which is both developer friendly and powerful Plus all the tooling around GraphQL is simply fantastic from ease of integration to code generators it s the perfect choice to reduce complexity on the frontend What and How Here we ll create a simple GraphQL server and subscribe to a subject from our resolver We ll use GraphQL playground to mock client side behavior Once we re connected we ll use NATS CLI to send a payload to our subject and see the changes on the client Note NATS client is available in over different languages Pre requisitesWe will require following tools to run our example so make sure you have these installed first NATS ServerNATS CLI SetupLet s start by setting up a basic GraphQL project using gqlgen which lets us autogenerate our schema resolvers and much more Note All the code from this article will be available in this repoInit a new go module mkdir example cd example go mod init exampleCreate a new gqlgen project printf build tools npackage tools nimport github com designs gqlgen gofmt gt tools go go mod tidy go run github com designs gqlgen init printf package model gofmt gt graph model doc goThis should create the following directory structure├ーgo mod├ーgo sum├ーgqlgen yml├ーgraph│├ーgenerated││└ーgenerated go│├ーmodel││├ーdoc go││└ーmodels gen go│├ーresolver go│├ーschema graphqls│└ーschema resolvers go├ーserver go└ーtools goBefore we run this let s simplify the graph schema graphqls as below to keep things as minimal as possible so we can focus on NATS integration more clearly type Subscription payload String type Query payload String Let s re generate our resolvers go run github com designs gqlgen generatevalidation failed packages Load nats gql graph schema resolvers go NewTodo not declared by package modelnats gql graph schema resolvers go Todo not declared by package modelnats gql graph schema resolvers go Todo not declared by package modelnats gql graph schema resolvers go MutationResolver not declared by package generatedexit status This should give an error which tells us to remove unused code from our resolvers To fix this simply open graph schema resolvers go and remove anything below the WARNING sign Now let s also change the query resolver Payload func r queryResolver Payload ctx context Context string error value hello world return amp value nil And finally let s run the server go run server go connect to http localhost for GraphQL playgroundWohoo Now we can go to localhost and run our sample query in GraphQL playground and it should give us a result Now that we have our basic GraphQL server working let s look into our subscription resolver defined in schema resolvers go But first let s understand the Payload resolver function As we know Go has this amazing concept of channels and if we look at the return signature this function requires us to return a receive only channel of type string along with error in case something goes wrong This seems quite idiomatic Go to me Note gqlgen will forward any data sent to this channel to the subcription func r subscriptionResolver Payload ctx context Context lt chan string error Note Notice that string will be changed if we update our schema and regenerate our resolversThis is perfect Let s install nats go go get github com nats io nats gogqlgen is setup in such a way that it makes it very easy to do dependency injection So let s init our NATS client But first let s update some types In graph resolver go update the Resolver type as below type Resolver struct Nats nats Conn Nice now we ll be able to init and pass our client to graph Resolver struct in server go nc err nats Connect nats DefaultURL if err nil panic err defer nc Close srv handler NewDefaultServer generated NewExecutableSchema generated Config Resolvers amp graph Resolver nc Great moving back to graph schema resolvers go let s define a channel and subscribe to a subject like payload subject In the callback function we ll simply convert our message data which is a byte array to string and send it to our channel func r subscriptionResolver Payload ctx context Context lt chan string error ch make chan string r Nats Subscribe payload subject func msg nats Msg payload string msg Data ch lt amp payload return ch nil Note You can easily setup an encoded connection to auto parse any json data NATS makes it super convenient Before we run our app let s open a new terminal window and start our NATS server nats server INF Starting nats server INF Version INF Git not set INF Name NDRHVHJHVJKXIAIXYZWLUEYTEGMRSOSCHLWQXEKAGSZJKBTIDA INF ID NDRHVHJHVJKXIAIXYZWLUEYTEGMRSOSCHLWQXEKAGSZJKBTIDA INF Listening for client connections on INF Server is readNote Want to run NATS in production Checkout my ealier article where we look at different ways of running a NATS server on Kubernetes Finally Let s start our app and navigate to localhost go run server go connect to http localhost for GraphQL playgroundLet s start a subscription for a query subscription payload Now it should be actively listening for changes Lastly let s publish a message usually this will be performed by a another service or client but right now we can just use the nats cli i e nats pub lt subject gt lt payload gt nats pub payload subject hello world ConclusionPerfect Now we can run our real time GraphQL subscriptions at scale all thanks to NATS which is capable of serving upto million messages per second yes you read that right I hope this article was helpful as always if you have any questions feel free to reachout to me on LinkedIn or
