app-builder


Create composable promise based middleware pipelines, using the "onion" middleware model.

Install:

npm install app-builder

Example

``javascript
import { compose } from 'app-builder'

const app = compose([
async function (ctx, next) {
ctx.value += 1
await next()
ctx.value += 4
},
async function (ctx, next) {
ctx.value += 2
await next()
ctx.value += 3
}
]);

const context = { value: '' }
app(context).then(() => console.log(context.value)) // --> '1234'

`

All composed functions are also valid middleware functions.

`javascript
const superApp = compose(
async function (ctx, next) {
ctx.value += 'first'
await next()
ctx.value += 'last'
},
app
)
