odata-v4-mongodb

library0.1.12jsnpmunverified

A library for converting OData v4 query segments (such as $filter, $select, $skip, $top) into MongoDB query objects. Version 0.1.12 is the latest and appears to be stable but early-stage, with limited release cadence. It depends on odata-v4-parser for OData syntax parsing. Key differentiator: enables building OData v4 compliant APIs directly over MongoDB, supporting filter, select, skip, top, but not yet $expand. Includes TypeScript definitions.

Code

Verified usage

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

createFilter

✓ import { createFilter } from 'odata-v4-mongodb'

✗ const createFilter = require('odata-v4-mongodb');

ESM import is preferred; TypeScript definitions included.

createQuery

✓ import { createQuery } from 'odata-v4-mongodb'

✗ var createQuery = require('odata-v4-mongodb').createFilter;

createQuery handles $filter, $select, $skip, $top together; common mistake to misname require destructure.

MongoDBDriver

✓ import type { MongoDBDriver } from 'odata-v4-mongodb'

✗ import { MongoDBDriver } from 'odata-v4-mongodb'

MongoDBDriver is a TypeScript type, not a runtime value; use 'import type' for correct usage.

Create an OData v4 endpoint over MongoDB using createFilter and createQuery with Express.

import { createFilter, createQuery } from 'odata-v4-mongodb'; import { Collection } from 'mongodb'; // Express endpoint example app.get('/api/products', async (req: any, res: any) => { try { const filter = createFilter(req.query.$filter || ''); const query = createQuery(req.query); const data = await collection.find(query).toArray(); res.json({ '@odata.context': `${req.protocol}://${req.get('host')}/api/$metadata#products`, value: data }); } catch (err) { res.status(400).json({ error: 'Invalid OData query' }); } });

Debug

Known issues

breakingcreateQuery expects a query object with $filter, $select, etc., not a string. Passing a string will return unexpected results.

fix

Pass req.query (object) or { $filter: '...', $select: '...' }.

affects: >=0.1.0

gotchaOData $orderby is not supported by createQuery in current version; will be ignored silently.

fix

Manually handle $orderby using MongoDB sort() after query.

affects: <=0.1.12

gotcha$expand is not supported; using it will cause createQuery to throw or ignore.

fix

Implement expand logic manually or avoid using $expand.

affects: <=0.1.12

deprecatedThe 'createFilter' function is stable but 'createQuery' is recommended for full query building.

fix

Use createQuery to handle $filter, $select, $skip, $top together.

affects: >=0.1.0

breakingVersion 0.1.0 introduced createQuery; previous versions only had createFilter. Code written for earlier versions may break.

fix

Update imports to include createQuery if needed.

affects: <0.1.0

Errors

Common errors & fixes

TypeError: odata_v4_mongodb_1.createFilter is not a function

Using CommonJS require without destructuring; odata-v4-mongodb exports a module with named exports, not a function.

fix

Use: const { createFilter } = require('odata-v4-mongodb');

Cannot find module 'odata-v4-mongodb'

Package not installed or missing dependency; required when using TypeScript or Node.js.

fix

Run: npm install odata-v4-mongodb

Argument of type 'string' is not assignable to parameter of type 'QueryOptions'

Passing raw query string instead of object to createQuery.

fix

Pass req.query object or { filter: req.query.$filter, select: req.query.$select }.

MongoError: unknown operator: $regex

Certain OData filter operators (like substringof) may convert to $regex which requires MongoDB 3.6+ or collision with escaped characters.

fix

Ensure MongoDB version >= 3.6, or sanitize inputs; avoid special regex characters.
