Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

Ey

Ey is an ergonomic and fast server+router, built on uWebSockets (for now). It has a simple interface embracing todays JS features.

Getting Started

import ey from 'ey'

const app = ey()

app.get('/', r => r.end('Hello World'))

const { port } = await app.listen(process.env.PORT)

The request

The request object contains all relavant data and methods to handle incoming requests and methods to respond as desired.

app.get(r => {
    r // is the request object
})

Incoming

.method

The HTTP verb of the request.

.url

Contains the actual url sent by the client

.pathname

Contains the relative url for the specific handler

.headers

An object containing headers. If multiple headers are found the value will be a comma separated list of values.

.query

A URLSearchParams object for the query string. This is a getter so the URLSearchParams object will be created lazily.

.params

An object of the matched routing params like. /authors/:author/books/:book = { author: 'Murray', book: 'Ethics of Liberty' }

.body() -> Promise

A function which reads the incoming body and transforms it to an optional type text or json. If no type is specificed a Buffer will be returned.

r.cookie(name) -> Object

Returns an object representing the cookie

Outgoing

.status(status)

.header(name, value) | r.header({ name: value })

.end(body)

.tryEnd(body)

.write()

.cork()

.offset()

.status()

.writable()

.close()

.cookie(name, { ... })

Middleware

Implement middleware with all. Ey forwards the request to the next handler, unless a response has begun.

app.all((r, next) => {
  r.headers.authorization
    ? r.token = r.headers.authorization.split(' ')[1]
    : r.statusEnd(401) // request ends here
})

app.all(r => {
    r.token
})

Optimizations

There are various ways to optimize your routes by being more specific in their definition.

Pre-specified request headers

You can specify which headers a route will use, up front, to prevent reading and loading unnecessary headers. Be aware that this is not possible for route handlers that come after other async handlers.

const app = ey({ headers: ['content-type'] })

app.get('/login', { headers: ['authorization'] }, r => {
  r.headers['content-type'] // string
  r.headers['authorization'] // string
  r.headers['accept'] // undefined    
})

Error handling

Any middleware that accepts 2 arguments will be registrered as an error handler and receive the error as the first argument, and the request object as the second. This will allow you to log errors and reply accordingly. If no error handler makes a response the default error handler will reply with 500 Internal Server Error and call console.error.

app.all((error, r) => {
  connected = true
  res.end(await ...)
})

Route matching

Routes are matched according to the order in which they are defined. This is important to support middleware with less specific route matching.

Exact match

| hej | med | yo | | -- | -- | -- | | /user | will only match requests to the url /user | |

Wildcard (not implemented yet)

/user* All requests that begins with /user /user/* All requests that begins with /user/ */user All requests that ends with /user

Parameters

/user

All requests with one path segment, setting r.params = { user }

/:user/posts/:post

All requests with 3 segments that has posts in the middle, setting r.params = { user, post }

Regex

Examples

Get

Get with Params

// GET /u25
app.get('/:id', r => 
  r.params.id // The actual id value
)

Get query params

// GET /?sort=-price
app.get(r => {
  req.query.sort // -price
})

Getting posted JSON

// POST /user { name: 'Murray' }
app.post('/user', async r => {
  const body = await r.body('json')
      , user = await sql`insert into users ${ sql(body) }`
      
  r.json(user, 201) // r.json sets Content-Type: application/json header
})

Send file

app.get('/favicon.ico', r => r.file('/public/favicon.ico'))

Serve files

app.all('/node_modules', r.files('/node_modules'))

File upload

// POST /file data
app.post('/file', async r => {
  await new Promise((resolve, reject) =>
    r.readable.pipe(fs.createWriteStream('...'))
     .on('finish', resolve)
     .on('error', reject)
  )
  r.end('Done')
})

Redirect

// GET /old-link
app.get('/old-link', async r => {
  r.statusEnd(302, { location: '/new-link' })
})

Auth

app.all(r => {
  const session = await sql`select * from sessions where key = ${ 
    r.headers.authorization.split(' ')[0] 
  }`  
})

The request object

Routing

Ey simplifies the express routing model, by removing request and next.
