## Import maps > This is an unstable feature. Learn more about > [unstable features](../runtime/stability.md). Deno supports [import maps](https://github.com/WICG/import-maps). You can use import maps with the `--importmap=` 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** ```js { "imports": { "fmt/": "https://deno.land/std@0.55.0/fmt/" } } ``` **color.ts** ```ts import { red } from "fmt/colors.ts"; console.log(red("hello world")); ``` Then: ```shell $ deno run --importmap=import_map.json --unstable color.ts ```
