MCP Community Begins Work on Official MCP Metaregistry
The MCP community is launching an official registry to standardize AI tool discovery and let agents dynamically find and install MCP servers.
A frontend cache-busting static middleware for express.
###Install
npm install --save bomb
###Example
Let's say we want to serve all the css, js and HTML files in our public directory:
├── index.js
└── public
├── example.css
├── example.js
├── other.txt
├── example.png
└── other
└── index.html
We can create a new bomb box and use it as a middleware:
var Express = require('express');
var Bomb = require('bomb');
var Path = require('path');
var app = Express();
var box = new Bomb.Box({
url: '/public', // use this as the URL root
path: Path.join(__dirname, 'public'), // look in this directory for files
regex: /\.(css|js|html)/ // only serve files that match regex
sendOptions: {} // options for the `send` module
});
app.use(box);
app.listen(4000);
We can now request the files on the natural or hashed URLS:
/public/example.css
/public/example-4591dd5c9fd5aab8f5d7df6ac939441c.css
/public/example.js
/public/example-00e062122c3306198fdbe5d3ddd01fe0.js
/public/other/index.html
/public/other/index-33c805c6162941684b6fc618d0e42ab8.html
To get the hashed URL from a natural one, just call box.getHashedUrl(url)
:
box.getHashedUrl('/public/example.css') === '/public/example-4591dd5c9fd5aab8f5d7df6ac939441c.css'
To get the natural URL from a hashed one, just call box.getNaturalUrl(url)
:
box.getNaturalUrl('/public/example-4591dd5c9fd5aab8f5d7df6ac939441c.css') === '/public/example.css'
