Vendor

This module allows you to download a JavaScript file and all of its dependencies to disk. Each file is parsed and checked for import statements. Any imports that are found within the file will be downloaded recursively until the entire module graph is written to disk.

Usage

import { vendor } from "https://deno.land/x/vendor/mod.js";

// Download the contents of mod.js and all of its dependencies to the 'deps' directory.
await vendor({
    entryPoints: ["https://deno.land/x/renda@v0.1.0/src/mod.js"],
    outDir: "./deps",
});

Why not use deno vendor or npm install?

This approach is mainly beneficial in cases where you wish to make your application runnable without a build step. Your local server might not be serving the node_modules directory, you might not be using node and npm at all, or maybe the third-party code you are trying to use is not available on npm.

Furthermore, deno vendor is mainly meant for vendoring code that is run by Deno. So things like import attributes are not supported. Deno also vendors everything including type imports. Third-party code may contain a /** @type {import("thisfiledoesntexist")} */ JSDoc comment, and the entire vendor operation will fail.
