node-autofixer

Watches your Node.js process. When it crashes, sends the error to AI, applies the fix, and restarts — automatically.

Install

npm install node-autofixer

Usage

import { AutoFixer } from 'node-autofixer'

const fixer = new AutoFixer()
fixer.watch('./bot.js')

That's it. Every crash gets fixed and logged in autofixer.log.txt.

Options

new AutoFixer({
  logFile: 'autofixer.log.txt',
  minConfidence: 0.5,
  maxRetries: 3,
  restartDelay: 1000,
})

| Option | Default | Description | |---|---|---| | logFile | autofixer.log.txt | Where to save errors and fixes | | minConfidence | 0.5 | Minimum AI confidence to apply a fix (0–1) | | maxRetries | 3 | Max fix attempts before giving up | | restartDelay | 1000 | Milliseconds to wait before restarting |

Log format

Every error and fix is saved in plain text:

============================================================
[12/03/2026, 14:32:01] ERROR DETECTED
============================================================
File:    /home/user/bot.js
Line:    12
Type:    ReferenceError
Message: myVar is not defined

Stack:

------------------------------------------------------------

[12/03/2026, 14:32:03] FIX APPLIED
------------------------------------------------------------
File: /home/user/bot.js

AI Explanation:
myVar was used before being declared. Added const myVar = null on line 11.

Fixed code:

How it works

1. Spawns your script as a child process
2. Intercepts stderr and crash events
3. Parses the error — file, line, stack trace
4. Sends error + source code to the AI proxy
5. AI returns a fix with confidence score
6. If confidence ≥ threshold, applies fix and restarts
7. Saves everything to the log file
