Why Node.Js Is So Popular Amongst Developers?

  • But, every creation has an origin that can never be taken out from it.
  • JavaScript is that origin that initiated the Web development that we see today, and Node.js is the most promising progeny of JavaScript.
  • There are many reasons why Node.js is so popular amongst developers and IT companies.

Build GraphQL APIs with Node.js on MongoDB

  • In REST, the server defines the shape and size of the resource provided by an endpoint.
  • Often this means multiple requests to the server to get precisely the data you want with far too much additional data provided.
  • GraphQL solves this problem by providing you (the consumer of the data) the ability to define exactly what you need while allowing you the freedom to request as much or as little data as you want.
  • In this course, you will learn how to set up a GraphQL server with Node.js and Express persisted by MongoDB.
  • Step by step, youll create GraphQL Mutations to update and delete data, GraphQL Queries to load all/specific data you need, and connect to MongoDB through Mongoose to persist the data on your server.

Threads in Node 10.5.0: a practical intro – DailyJS – Medium

  • The output of the above piece ofcodeLets break it down: – The code inside the IF statement creates 2 worker threads, the code for them is taken from the same file, due to the __filename parameter passed.
  • Example 2: Actually doing something – Lets try now to do some heavy computation while at the same time, doing some async stuff in the main thread.
  • You could also send a message to the threads code using the same method, on your worker instance and catching them using the parentPortobject.
  • Lets now look at a very similar example, but with a cleaner code, giving you a final idea of how you could structure your worker threads code.
  • And your thread code can be inside another file, such as: – Breaking this one down, we see: – Main thread and worker threads now have their code inside different files.

End-to-end testing Single Page Apps and Node.js APIs with Cucumber.js and Puppeteer

  • Here is how the Cucumber feature file might be at this stage: – The Cucumber scenario describes the steps from the beginning to the end, and are written in a fashion that would allow anyone to be able to read them and understand what is going on.
  • We would then install Cucumber as a development dependency in the application, by typing this into the command line: – npm i cucumber -DWith Cucumber installed, we can now use it to read in the feature file inside of the features folder, parse the steps, and print out code that…
  • feature file extension in the features folder – Look for files that contain step definition functions – Look for a hooks.js file in the features folder – Look for a world.js file in the features folder – Look for any step definition functions that are in the step_definitions folder -…
  • It will look something like this: – The next time that you run npx cucumber-js, you will see that those step definitions are being matched: – Youll now see from the output that Cucumber has matched the steps in the feature file to the steps that we put in the…
  • We are now in a position to start writing code for our step definition files which will execute when we run Cucumber, such as writing code that would trigger doing things inside a web browser.
