Can Tilelive host many mbtiles files?

Hi,

I am using a tilelive server to host my mbtiles files and load them locally. Currently, my server looks like this (taken from this post):

var express = require('express');
var http = require('http');
var app = express();
var tilelive = require('@mapbox/tilelive');
require('@mapbox/mbtiles').registerProtocols(tilelive);

tilelive.load('mbtiles://./file.mbtiles', function(err, source) {

    if (err) {
        throw err;
    }
    app.set('port', 7777);

    app.use(function(req, res, next) {
        res.header("Access-Control-Allow-Origin", "*");
        res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
        next();
    });

    app.get(/^\/v2\/tiles\/(\d+)\/(\d+)\/(\d+).pbf$/, function(req, res){

        var z = req.params[0];
        var x = req.params[1];
        var y = req.params[2];

        console.log('get tile %d, %d, %d', z, x, y);

        source.getTile(z, x, y, function(err, tile, headers) {
            if (err) {
                res.status(404)
                res.send(err.message);
                console.log(err.message);
            } else {
              res.set(headers);
              res.send(tile);
            }
        });
    });

    http.createServer(app).listen(app.get('port'), function() {
        console.log('Express server listening on port ' + app.get('port'));
    });
});

But, I want to be able to host multiple mbtiles files. For instance, if tilelive could load file1.mbtiles and file2.mbtiles. Then, my query could look like localhost:7777/v2/tiles/file1/{z}/{x}/{y}.pbf. But, I'm not sure how to specify tilelive to load multiple tiles.

Please let me know if you have any ideas. Thanks!

Start with the tilelive.load call and the Express tile route shown in the issue. Determine how a requested file name can select among file1.mbtiles and file2.mbtiles while preserving tile retrieval. Done means the server serves tiles from the selected MBTiles file through the proposed /v2/tiles/file1/{z}/{x}/{y}.pbf form.
