koa-pass

Conditionally skip a middleware when a condition is met.

NB: koa-pass@1 for koa@1.

Install

$ npm i koa-pass --save

Usage

middleware.pass = require('koa-pass')
middleware.pass(opts, _pathToRegexpOpts)

• opts: {Object|Array}
  • method: {String|Array} http method, required.
  • path: {String} path for path-to-regexp, required.
  • pass: {Boolean|Function} if return true then pass, optional, default true.
• _pathToRegexpOpts: {Object} see path-to-regexp.

Examples

const Koa = require('koa')
const res = require('koa-res')()
res.pass = require('./')

const app = new Koa()
app.use(res.pass([
  { method: 'GET', path: '/pass' }
]))
app.use((ctx) => {
  ctx.body = 'ok'
})
app.listen(3000, () => {
  console.log('listening on 3000')
})

or:

const Koa = require('koa')
const res = require('koa-res')()
res.pass = require('./')

const app = new Koa()
app.use(res.pass({
  method: 'GET',
  path: '/:name',
  pass: async (ctx) => {
    return ctx.path === '/pass'
  }
}))
app.use((ctx) => {
  ctx.body = 'ok'
})
