deno_proxy

Start a proxy server locally to cache Deno resources. The main reason is the current deno land occasionally fails to download.

start server

deno run --allow-net --allow-read --allow-write --allow-env https://deno.land/x/deno_proxy@v1.4.0/mod.ts

Then your server will be started on http://localhost. You can use like this:

import { VERSION } from "http://localhost/https/deno.land/std@0.140.0/version.ts";

console.log(VERSION);

It just changed your origin URL https://deno.land to http://localhost/https/deno.land.

use cli to generate one typescript or javascript file

deno run --allow-read --allow-write https://deno.land/x/deno_proxy@v1.4.0/cli/mod.ts --baseUrl http://localhost:8000 --oldPath example/deps.ts --newPath example/deps_proxy.ts

use cli to generate import_map.json

If your import_map.json like this:

{
  "imports": {
    "/std/": "https://deno.land/std@0.140.0/"
  }
}

Then generate your proxy import_map.json by the above:

deno run --allow-read --allow-write https://deno.land/x/deno_proxy@v1.4.0/cli/mod.ts --baseUrl http://localhost:8000 --oldPath example/import_map.json --newPath example/import_map_proxy.json

The import_map_proxy.json should be this:

{
  "imports": {
    "/std/": "http://localhost:8000/https/deno.land/std@0.140.0/"
  }
}

If you have to ignore your urls, you can add ignoreOrigins such as --ignoreOrigins /baidu.com/,/xunlei.cn/.

Then you can run your code:

deno run -A --import-map ./example/import_map_proxy.json ./example/mod.ts
