hooks

use

In addition to the hooks provided by psychic, you can tap into express middleware directly by leveraging the use method. This method acts similarly to the express use api for most use cases.

psy.use((req, res, next) => {
  res.json({ hello: 'world' })
})

If you need to inject at a specific point during the build cycle, you can provide an optional first argument, which will cause your middleware to run at the specified point:

// runs before any psychic middleware (i.e. cors) has been processed
psy.use('before-middleware', (req, res, next) => {
  res.json({ hello: 'world' })
})

// runs after all psychic middleware has been provided
psy.use('after-middleware', (req, res, next) => {
  res.json({ hello: 'world' })
})

// runs after all routes in the conf/routes.ts file have been processed
psy.use('after-routes', (req, res, next) => {
  res.json({ hello: 'world' })
})
