express-restify-mongoose-queryizer

Middleware for express-restify-mongoose which allows direct querying via GET without JSON structures.

The 2.0.0 release of ERM moved GET based querying into the query structure like this:

http://myserver.com/api/widgets?query={"type":"foobar"}&sort=title

This middleware layer allows the old-style method of filtering directly within the GET request:

http://myserver.com/api/widgets?type=foobar&sort=title

Meta fields and the existing query structure is still maintained allowing for compatibility with regular ERM query syntax.

Installation

Install via NPM:

npm --save install express-restify-mongoose-queryizer

Then somewhere in your express application install it as middleware:

app.use(require('express-restify-mongoose-queryizer')({

	// Whether to rewrite queries (see above examples)
	rewriteQuery: true,

	// If we do rewrite should we also remove the key from req.query (not recommended if you have other middleware that relies on req.query)
	rewriteQueryDeleteKeys: false,

	// Only rewrite query strings during GET operation
	rewriteGetOnly: true,

	// Allow JSON objects as values
	rewriteParseJSON: true,

	// Also use the HSON parser (allows non-quoted strings) instead of the plain JSON.parse()
	rewriteParseHSON: true,

	// Rewrite 'POST' operations to 'PATCH'
	postToPatch: true,

	// ... but only if they match this URL format - e.g. /api/widgets/56c528046ce4b00f517eb55c
	postToPatchUrl: /^\/api\/.+\/[0-9a-f]{24}$/,
}));
