An alternative to
deno info, supports non-standard file imports, such as .css, .svg, etc
import { getDeps } from "https://deno.land/x/deps_info@v0.2.0/mod.ts";
const scriptSet = await getDeps("https://jspm.dev/jsdom");ScriptSet has the following methods.
class ScriptSet
add(script: Script)
has(url: string): boolean
get(url: string): Script | undefined
get length()
get scripts()
async loadDeps(url: string): Promise<void>
You can load further dependency scripts by calling scriptSet.loadDeps(url).
const scriptSet = await getDeps("https://jspm.dev/jsdom");
await scriptSet.loadDeps("https://esm.sh/react");
await scriptSet.loadDeps("https://esm.sh/react-dom");
...In the above APIs, Script has the shape below:
export interface Script {
url: string;
redirectedUrl: string;
contentType: string;
source: string;
imports: string[];
}This module 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")).scripts;
/* 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",
"imports": [
"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",
"imports": []
}
]
*/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",
);The command below installs the cli version of this tool.
deno install -qf --allow-read --allow-write=. --allow-net --name deps_info https://deno.land/x/deps_info@v0.2.0/cli.ts
You can show the dependencies in tree format in the terminal.
