drop-mongodb-collections

library2.0.0jsnpmunverified

A utility to drop all non-system collections from a MongoDB database. Version 2.0.0 is stable, with infrequent releases. It is designed specifically for test setup/teardown, accepting a MongoDB URI and returning a cleanup function. Unlike generic drop-database tools, it preserves system collections and integrates easily with Mocha's beforeEach.

Code

Verified usage

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

default

✓ import dropMongoDbCollections from 'drop-mongodb-collections';

✗ const dropMongoDbCollections = require('drop-mongodb-collections');

ESM export since v2.0.0; CJS require no longer works.

dropMongoDbCollections as function

✓ const cleanup = dropMongoDbCollections('mongodb://localhost/tests');

✗ dropMongoDbCollections('mongodb://localhost/tests')();

Function returns a cleanup function; do not call twice.

Type import (TypeScript)

✓ import type { DropMongoDbCollections } from 'drop-mongodb-collections';

✗ const { DropMongoDbCollections } = require('drop-mongodb-collections');

Type-only import for TypeScript users; lib ships with types.

Shows ESM import, factory usage with env URI, and Mocha integration.

import dropMongoDbCollections from 'drop-mongodb-collections'; const cleanup = dropMongoDbCollections(process.env.MONGO_URI ?? 'mongodb://localhost/test'); // In Mocha beforeEach(cleanup); // Or manually await cleanup();

Debug

Known issues

breakingv2.0.0 dropped CommonJS support; package is now ESM-only.

fix

Use ESM import syntax or pin to v1.x if CJS required.

affects: >=2.0.0

gotchaFunction returns a cleanup function; calling dropMongoDbCollections() multiple times creates separate instances.

fix

Store return value and reuse it.

affects: *

deprecatedv1.x used callback style; v2.0.0 returns promise.

fix

Upgrade to v2 and use await or .then.

affects: <2.0.0

Errors
