TypeScript

BlockJS is designed with TypeScript support in mind. Adding TypeScript to BlockJS is as simple as creating a tsconfig.json and configuring a couple settings.

Adding TypeScript to BlockJS​

If you haven't already setup BlockJS, you can find how to do so in the quickstart guide. Otherwise, in your scripts folder, create a tsconfig.json file.

Configuring TypeScript​

In your tsconfig's compilerOptions, there are a few items you have to set:

  • module: 'commonjs', this tells the TypeScript compiler to compile and ECMAScript modules we may use to CommonJS syntax at compilation.

  • target: 'ES2015', this tells the TypeScript compiler to target the ES2015 syntax of JavaScript.

  • esModuleInterop: true, this option being true lets us import CommonJS modules as if they were ECMAScript modules.
