koa-mount-pattern

As you may know, there's a famous middleware called koa-mount which is used to mount a middleware to a specific path. But what if you want to mount a middleware to a path pattern? For example, you want to mount a middleware to all paths that start with /api/(v1|v2|v3)? This is where koa-mount-pattern comes in.

Installation

npm install koa-mount-pattern

Usage

const Koa = require('koa');
const { mountPattern } = require('koa-mount-pattern');

const app = new Koa();
app.use(mountPattern('/api/:version', async (ctx, next) => {
  // do something
  await next();
}));
