deps_info v0.1.0

An alternative to deno info, supports non-standard file imports, such as .css, .svg, etc

APIs

getDeps

import { getDeps } from "https://raw.githubusercontent.com/kt3k/deps_info/main/mod.ts";

const scripts = await getDeps("https://jspm.dev/jsdom");

scripts has the type of Script[], where Script has the shape below:

export interface Script {
  url: string;
  redirectedUrl: string;
  contentType: string;
  source: string;
  dependencyUrls: string[];
}

getDeps doesn’t throw even when the script imports a file with unknown media type.

foo.js

import "bar.css";
console.log("foo");

bar.css

body {
  margin: 0;
}
await getDeps("./foo.js");
/* This returns:
[
  {
    "url": "file:///Users/kt3k/oss/deps_info/foo.js",
    "redirectedUrl": "file:///Users/kt3k/oss/deps_info/foo.js",
    "contentType": "text/javascript",
    "source": "import \"./bar.css\";\nconsole.log(\"foo\");\n",
    "dependencyUrls": [
      "file:///Users/kt3k/oss/deps_info/bar.css"
    ]
  },
  {
    "url": "file:///Users/kt3k/oss/deps_info/bar.css",
    "redirectedUrl": "file:///Users/kt3k/oss/deps_info/bar.css",
    "contentType": "text/css",
    "source": "body {\n  margin: 0;\n}\n",
    "dependencyUrls": []
  }
]
*/

getDeps uses ./.deps_info_cache by default as the cache directory for donwloaded files. You can change this by passing it as the 2nd argument.

const scripts = await getDeps(
  "https://jspm.dev/jsdom",
  "/path/to/cache/directory",
);
