TypeScript in Moyuk

Moyuk's TypeScript aims to be as compatible as possible with Deno's. (Not fully compatible yet.)


Moyuk doesn't support customizing compiler options yet. The tsconfig.json set by Moyuk looks like this:

"compilerOptions": {
"allowJs": true,
"esModuleInterop": true,
"experimentalDecorators": true,
"inlineSourceMap": true,
"isolatedModules": true,
"module": "esnext",
"moduleDetection": "force",
"strict": true,
"target": "esnext",
"useDefineForClassFields": true

Moyuk's compiler options are basically same as Deno's.


You can import modules from https: or npm: URLs just like in Deno.

Moyuk currently supports importing modules from:

Using npm packages

Importing npm packages with npm specifiers

Moyuk supports importing modules from npm packages via npm: URL.

import { marked } from 'npm:marked@^4.2';

Moyuk uses internally to resolve npm specifiers.


Not all npm packages work with Moyuk. Npm packages that use Node.js built-in modules or native modules won't work.

Importing npm packages with CDNs

Moyuk supports importing modules from CDNs that support X-TypeScript-Types header via https: URL.

import { marked } from '[email protected]';

Here is the list of the CDNs that support X-TypeScript-Types:

TypeScript version

You can check the TypeScript version in the App Info tab. Moyuk uses the latest TypeScript version.
