fixImport

日本語のREADMEはこちらです: README.ja.md

A Deno utility to automatically correct relative import paths in JavaScript and TypeScript files. It ensures that local module imports include the appropriate .js extension, which is often required in browser environments or for ES Modules in Node.js.

Features

• Adds .js Extension: Automatically appends .js to relative import paths that lack an extension (e.g., from "./utils" becomes from "./utils.js").
• Replaces .ts Extension: Converts .ts extensions in import paths to .js (e.g., from "./types.ts" becomes from "./types.js").
• Handles Complex Imports: Correctly parses and fixes both single-line and multi-line import statements.
• CLI for Bulk Operations: Provides a command-line tool to fix a single file or recursively fix all .js, .ts, and .mjs files in a directory.
• Preserves Quote Style: Maintains the original quote style (single or double) of the import statement.

Installation (Command-Line Tool)

You can install the CLI globally using Deno:

deno install -n fiximport --allow-read --allow-write https://code4fukui.github.io/fixImport/cli.js

Command-Line Usage

After installation, you can use the fiximport command.

Fix all files in the current directory

Run the command without arguments to scan the current directory and all subdirectories. It will prompt for confirmation before modifying any .js, .ts, and .mjs files.

fiximport

Fix a specific file

Provide a file path as an argument to fix a single file.

fiximport path/to/your/file.js

Programmatic Usage

You can also use fixImport as a function within your Deno projects.

import { fixImport } from "https://code4fukui.github.io/fixImport/fixImport.js";

const brokenCode = 'import { some } from "./some";\nimport { other } from "./other.ts";';
const fixedCode = fixImport(brokenCode);

console.log(fixedCode);
// Output:
// import { some } from "./some.js";
// import { other } from "./other.js";
