bundle-import v0.0.1

Bundle-import

Bundle and load a file using the import-from-string.

Difference from bundle-require

Most of the code of Bundle-import comes from bundle-require. There is no objection to this, but Bundle-import does not generate temporary files when reading module contents, which can avoid conflicts with other tools. For example, the following two issues:

1. Tmp .mjs file in the current directory breaks other tools
2. vite 运行时，修改mock文件会生成很多个xxx.mjs文件

Features

• Support ESM and CJS environments
• Support dynamic import
• Support import.meta.url
• Support access to global variables
• No asynchronous IO operations
• No module cache

Install

npm install bundle-import

Usage

ESM

import { bundleImport } from "bundle-import";

const { mod: mod1 } = await bundleImport({ filepath: "./fixtures/index.cjs", cwd: process.cwd() + "/playground" });
console.log(mod1);

const { mod: mod2 } = await bundleImport({ filepath: "./playground/fixtures/index.mjs" });
console.log(mod2.default, mod2);

CJS

const { bundleImport } = require("bundle-import");

async function main() {
	const { mod: mod1 } = await bundleImport({ filepath: "./fixtures/index.cjs", cwd: process.cwd() + "/playground" });
	console.log(mod1);

	const { mod: mod2 } = await bundleImport({ filepath: "./playground/fixtures/index.mjs" });
	console.log(mod2.default, mod2);
}

main();
