Partial pattern matching

[ImSingee]

What is the problem this feature would solve?

Currently, we have two response formats for one API: xml and json:

POST /api/xxx.json
POST /api/xxx.xml

I want to register something like this:

/api/user/:id.json
/api/user/:id.xml

But it fails - currently, elysia see id.json and id.xml as param name, so what I want doesn't work.

What is the feature you are proposing to solve the problem?

Allow a "partial matching": /api/user/:id.json matches a request starts with /api/user/ and ends with .json, then use the middle thing as id param.

What alternatives have you considered?

No response

Try using regular expressions in the format?

export default new Elysia().use(openapi()).get(
	"/api/user/:id",
	({ params: { id } }) => {
		return id;
	},
	{
		params: t.Object({
			id: t.String({
				// end ".json"
				pattern: ".json$",
			}),
		}),
	},
);
