mongodb-js-errors

library0.5.0jsnpmunverified

Helpers for handling errors from the MongoDB driver. Version 0.5.0 (latest 2017). Low release cadence; no updates since 2017. Provides an error class hierarchy (MongoError, WriteError, etc.) and an Express middleware for uniform error responses. Simpler than the native MongoDB driver's error handling, but limited in scope.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

MongoError

✓ import { MongoError } from 'mongodb-js-errors'

✗ const MongoError = require('mongodb-js-errors').MongoError

ESM import is correct; require destructuring works too.

WriteError

✓ import { WriteError } from 'mongodb-js-errors'

✗ const { WriteError } = require('mongodb-js-errors')

Named import available from v0.1.0.

express middleware

✓ import expressMiddleware from 'mongodb-js-errors/express'

✗ const expressMiddleware = require('mongodb-js-errors').express

Express middleware is exported as default from the subpath 'mongodb-js-errors/express'.

Shows importing error classes, using Express middleware to handle MongoDB errors with HTTP status codes.

import express from 'express'; import { MongoError, WriteError } from 'mongodb-js-errors'; import errorHandler from 'mongodb-js-errors/express'; const app = express(); app.get('/', (req, res) => { // Simulate a MongoDB write error const err = new WriteError('Duplicate key', { code: 11000 }); next(err); }); app.use(errorHandler); app.use((err, req, res, next) => { const payload = err.output.payload; res.status(err.output.statusCode).json(payload); }); app.listen(3000);

Known issues

deprecatedPackage is no longer maintained; no updates since 2017.

fix

Consider using native MongoDB driver error handling or a maintained alternative.

affects: >=0.0.0

breakingBoom dependency may introduce breaking changes in error output structure if upgraded.

fix

Pin boom version to 4.x or handle error output manually.

affects: >=0.5.0

gotchaExpress middleware path is 'mongodb-js-errors/express', not from main export.

fix

Import from 'mongodb-js-errors/express' directly.

affects: >=0.1.0

gotchaError classes require boom for output; without boom, err.output is undefined.

fix

Ensure boom@4 is installed as a peer dependency.

affects: >=0.0.0

Errors

Common errors & fixes

Cannot find module 'mongodb-js-errors/express'

Incorrect import path or not using subpath import.

fix

Use 'mongodb-js-errors/express' (no trailing slash).

TypeError: Cannot read property 'output' of undefined

Error object does not have output property because boom is missing or not wired.

fix

Install boom and ensure it's imported/required before using error classes.
