ES Module Import Extractor

ES Module Import Extractor processes es module source directly in the browser and produces an inspectable, copy-ready result. It validates the input before conversion, reports useful counts, and keeps the original text available for correction. The implementation focuses on the rules that matter for this format instead of hiding failures behind a generic output. No source code, byte sequence, or text value is sent to a server.

How to use this developer tool

  1. Paste es module source or load the included sample.
  2. Choose only the options that match the target runtime or output.
  3. Select Extract Imports or press Ctrl/Cmd + Enter.
  4. Read the summary and diagnostics, then copy or download the result.

What this developer tool does

The result panel shows the exact output produced from the current input. Counts and status fields are derived during the same pass, so they describe the visible result rather than an estimate.

Input is parsed and validated first. The selected options are then applied in a deterministic pass, followed by format-specific statistics and a downloadable representation.

An error leaves the output blank. Correct the reported input issue and run the tool again rather than relying on a partial conversion.

Example

The sample demonstrates a representative es module source case, including characters or syntax that often expose parser mistakes.

import def, { readFile as read } from 'node:fs/promises'; import type { User } from './types.js'; import './setup.js'; const lazy = import('./feature.js');

Use cases

  • Checking data before committing generated files
  • Tracing encoding or syntax differences during debugging
  • Preparing a reviewed snippet for documentation or tests
  • Comparing browser output with a build tool or runtime

Tips for reliable output

  • Keep a copy of the unmodified source when testing conversions.
  • Use the sample first to confirm the selected output style.
  • Read the interpretation message, not just the output text.
  • Test edge cases from the runtime that will consume the result.
  • For large inputs, download the output instead of selecting it manually.

Processing details

The page uses standard browser JavaScript APIs and operates without external dependencies. Parsing, conversion, statistics, copying, and file creation all happen in the current tab.

This focused browser utility is not a full compiler, linter, Unicode database, or build pipeline. Its output reflects the current browser engine and the documented input rules.

Frequently asked questions

What input does ES Module Import Extractor accept?

Paste es module source. Processing stays in the browser and no network request is needed.

Does ES Module Import Extractor change the original input?

No. The input remains in the editor; the tool writes a separate, copy-ready result.

How does this tool handle invalid input?

It stops with a specific validation message instead of producing a partial result that looks usable.

Can I use the output in a production project?

Review it against your runtime and project conventions first, especially where JavaScript engine support or Unicode behavior matters.

Does ES Module Import Extractor upload my code or text?

No. Conversion and inspection run locally in the current browser tab.
