Usage
import middleware from 'syncano-middleware';
// Example middlewares.
const steps = {
auth: () => new Promise((resolve, reject) => {
// Your user authentication logic...
resolve(user)
}),
validate: () => new Promise((resolve, reject) => {
// Your validation logic...
resolve(formFields)
})
}
middleware([ steps.auth, steps.validate ])
.then(data => {
// All middlewares passed.
// Now you have an authenticated user and validated form.
const [ user, fields ] = data
})
.const(err => {
// An error occurred in one of middlewares.
// You can handle that here.
})
Middleware must be a function that returns a Promise:
function MyAwesomeMiddleware() {
return new Promise((resolve, reject) => {
// Your awesome middleware implmentation...
// ...
// resolve(data)
// or
// reject('An error message or data')
})
}
