Koa Context Cache Control

Augments Koa with ctx.cacheControl() and ctx.response.cacheControl().

Example

const Koa = require('koa')

const app = new Koa()

require('koa-ctx-cache-control')(app)

app.use(async (ctx, next) => {
  ctx.cacheControl(false) // no cache

  await next()
})

API

ctx.cacheControl()

If it's a time ms can parse, then it uses that time as the max age:

ctx.cacheControl('1 second') // => max-age=1

Otherwise, it sets the header directly:

ctx.cacheControl('max-age=0') // => max-age=0

ctx.cacheControl(ms)

Sets the max age with a number in milliseconds.

ctx.cacheControl(1000) // => max-age=1

ctx.cacheControl(false)

Sets a no cache directive.
