Import maps

This is an unstable feature. Learn more about unstable features.

Deno supports import maps.

You can use import maps with the --import-map=<FILE> CLI flag.

Current limitations:

• single import map.
• no fallback URLs.
• Deno does not support std: namespace.
• supports only file:, http: and https: schemes.

Example:

import_map.json

`

{   "imports": {      "fmt/": "https://deno.land/std@0.84.0/fmt/"   }}

`

color.ts

`

import { red } from "fmt/colors.ts";
console.log(red("hello world"));

`

Then:

`

$ deno run --import-map=import_map.json --unstable color.ts

`

To use starting directory for absolute imports:

`

// import_map.json
{  "imports": {    "/": "./"  }}

`

`

// main.ts
import { MyUtil } from "/util.ts";

`

You may map a different directory: (eg. src)

`

// import_map.json
{  "imports": {    "/": "./src/"  }}
