Service OData v4 requests from a MongoDB data store.
The OData V4 MongoDB Connector provides functionality to convert the various types of OData segments into MongoDB query objects, that you can execute over a MongoDB database.
- Create high speed, standard compliant data sharing APIs
import { createFilter } from 'odata-v4-mongodb'
//example request: GET /api/products?$filter=category/id eq 5 or color eq 'Red'
app.get("/api/products", (req: Request, res: Response) => {
const filter = createFilter(req.query.$filter);
// collection instance from MongoDB Node.JS Driver
collection.find(filter, function(err, data){
res.json({
'@odata.context': req.protocol + '://' + req.get('host') + '/api/$metadata#products',
value: data
});
});
});var createFilter = require('odata-v4-mongodb').createFilter;
app.get("/api/products", function(req, res) {
var filter = createFilter(req.query.$filter);
// collection instance from MongoDB Node.JS Driver
collection.find(filter, function(err, data){
res.json({
'@odata.context': req.protocol + '://' + req.get('host') + '/api/$metadata#products',
value: data
});
});
})For now $filter, $select, $skip and $top
Support for $expand is next.
The OData v4 Parser layer supports 100% of the specification. The Connector is supporting basic MongoDB queries.
We are into creating a comprehensive feature availability chart for V1 release
