The common misconception about TypeScript

• TypeScript

  1,305 97,944 9.9 TypeScript

  TypeScript is a superset of JavaScript that compiles to clean JavaScript output.

  

Recently my friend started learning TypeScript, yesterday he came to me with a doubt, he ran into a problem and he couldn't figure it out for days. (He is a newbie but a curious learner). His doubt made me realize a common misconception some people have about TypeScript. So I am writing this post to explain what leads to the misconception and how it can be rectified. Please note: This post is for newbies and aspiring JavaScript developers, an experienced developer would feel this is an obvious thing.

• validator.js

  String validation

• SurveyJS

  surveyjs.io sponsored

  Open-Source JSON Form Builder to Create Dynamic Forms Right in Your App. With SurveyJS form UI libraries, you can build and style forms in a fully-integrated drag & drop form builder, render them in your JS app, and store form submission data in any backend, inc. PHP, ASP.NET Core, and Node.js.

  

• React

  1,693 221,803 9.9 JavaScript

  The library for web and native user interfaces.

  

My friend was actually trying to build a front-end using React and TypeScript. I may not reveal the exact details of what he was trying to achieve but I try to give similar example. His setup had a web-server written using Express.js and it had some APIs. Some part of the front-end code made a GET request to the API and receives the response in JSON format, then it would manipulate the content to display the result on the web-page. I will try to simulate such environment by writing two script files.

• Mongoose

  108 26,621 10.0 JavaScript

  MongoDB object modeling designed to work in an asynchronous environment.

  

These libraries can perform validation on complex objects using simple schema definitions. You can also look at how Mongoose ODM does schema validation against MongoDB data and follow a similar schema structure.

• PyLD

  28 580 5.2 Python

  JSON-LD processor written in Python

  

Implement dynamic schema validation system and let the front-end fetch infer the schema from the backend and change it's validation flow accordingly, by this way you can avoid changing schema at multiple places. Check [https://json-ld.org/] for a similar analogy.

• gRPC

  201 40,733 9.9 C++

  The C based gRPC (C++, Python, Ruby, Objective-C, PHP, C#)

  

You can also consider Protobuf + gRPC instead of HTTP/s + REST.
