library0.0.2jsnpmunverified

Converts MongoDB duplicate key errors (error code 11000) into Mongoose ValidationError instances. This plugin leverages Mongoose's error handling middleware introduced in Mongoose 4.5. It is an unmaintained, early-stage plugin with limited functionality—only duplicate key errors are transformed. The current version 0.0.2 is stable but minimal, with no recent updates. Compared to alternatives like mongoose-unique-validator, this plugin integrates as a Mongoose plugin but lacks active development and broader error coverage.

Code
Verified usage

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

default
✓ const mongodbErrorHandler = require('mongoose-mongodb-errors');
✗ import mongodbErrorHandler from 'mongoose-mongodb-errors';
Package provides a CommonJS default export; no named exports exist. ESM import may fail in non-transpiled environments.
plugin usage
✓ mongoose.plugin(mongodbErrorHandler);
✗ mongoose.plugin(require('mongoose-mongodb-errors').default);
Common pattern: .default is incorrect if using require; only needed for ESM interop.
schema plugin
✓ schema.plugin(mongodbErrorHandler);
✗ schema.plugin(mongodbErrorHandler());
The plugin is a function, not a factory. Calling it will cause unexpected behavior.

Connects to MongoDB, defines a User schema with a unique username, applies the plugin, and demonstrates catching a duplicate key error as a Mongoose ValidationError.

const mongoose = require('mongoose'); const mongodbErrorHandler = require('mongoose-mongodb-errors'); mongoose.connect(process.env.MONGO_URI || 'mongodb://localhost/test'); const UserSchema = new mongoose.Schema({ username: { type: String, unique: true } }); UserSchema.plugin(mongodbErrorHandler); const User = mongoose.model('User', UserSchema); const user = new User({ username: 'existing' }); user.save().catch(err => { // err is a Mongoose ValidationError, not raw MongoError console.log(err.name); // 'ValidationError' console.log(err.errors.username.message); // e.g., 'Duplicate key error: username' });
Debug
Known issues
gotchaOnly transforms MongoDB error code 11000 (duplicate key). Other MongoDB errors (e.g., 11001) are not converted.
fix
Handle other error types manually or look for alternative plugins.
affects: <=0.0.2
deprecatedPackage is unmaintained with no updates since initial release. May not work with newer Mongoose versions.
fix
Consider using mongoose-unique-validator or mongoose's built-in unique error handling.
affects: >=0.0.2
gotchaRequires Mongoose >=4.5. Using with older Mongoose versions will cause errors.
fix
Update Mongoose to version 4.5 or newer.
affects: <=4.5
gotchaThe plugin must be applied before the schema is used. Applying after model creation will have no effect.
fix
Apply the plugin globally via mongoose.plugin() before defining schemas, or on each schema before model compilation.
affects: <=0.0.2
Errors
Common errors & fixes
TypeError: mongodbErrorHandler is not a function
Incorrect import attempt using default export instead of CommonJS require.
fix
Use require('mongoose-mongodb-errors') correctly: const mongodbErrorHandler = require('mongoose-mongodb-errors');
MongooseError: `mongoose` version 4.4.x is not supported. Please upgrade to >=4.5.0
Mongoose version is too old; the plugin uses error handling middleware introduced in 4.5.
fix
Upgrade Mongoose to version 4.5 or later with npm install mongoose@latest
Error [ERR_REQUIRE_ESM]: require() of ES Module ... not supported
Attempting to require the package in an ESM-only environment (e.g., Node with type: module). This package is CommonJS only.
fix
Use dynamic import: const mongodbErrorHandler = await import('mongoose-mongodb-errors'); or convert your project to CommonJS.
