Import maps

Deno supports import maps.

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

Example:

import_map.json

1. {
2. "imports": {
3. "fmt/": "https://deno.land/std@$STD_VERSION/fmt/"
4. }
5. }

color.ts

1. import { red } from "fmt/colors.ts";

3. console.log(red("hello world"));

Then:

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

To use your project root for absolute imports:

import_map.json

1. {
2. "imports": {
3. "/": "./",
4. "./": "./"
5. }
6. }

main.ts

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

This causes import specifiers starting with / to be resolved relative to the import map’s URL or file path.
