helpers to get fastify request/reply and app
npm install fastify-asyncforgeProvide easy AsyncLocalStorage magic to your
Fastify apps. It's based on asyncforge.
``sh`
npm i fastify fastify-asyncforge
`js
// app.mjs
import fastify from 'fastify'
import doWork from './do-work.mjs'
import asyncforge, { logger } from 'fastify-asyncforge'
const app = fastify({
logger: true
})
await app.register(asyncforge)
app.runInAsyncScope(() => {
logger().info('hello')
})
app.decorate('foo', 'bar')
app.decorateRequest('a')
app.decorateReply('b')
app.addHook('onRequest', async function (req, reply) {
req.a = 'a'
reply.b = 'b'
})
app.get('/', async function (request, reply) {
doWork()
return { hello: 'world' }
})
app.listen({ port: 3000 })
// do-work.mjs
import { logger, app, request, reply } from 'fastify-asyncforge'
export default function doWork () {
const log = logger()
log.info({
foo: app().foo,
a: request().a,
b: reply().b
}, 'doing work')
}
`
In case .runInAsyncScope() is incovenient, you can use .enterWith()
`js
import fastify from 'fastify'
import asyncforge from 'fastify-asyncforge'
const fastify = Fastify()
// Calling .enterWith() is necessary or asyncforge.app() will throw`
fastify.enterWith()
asyncforge.app()
Note that you cannot wrap .enterWith()` inside an async function, as it will not work.
