This seems fine

code:

// @flow
const data = document.body.getAttribute('my-attribute') || '{}'
const result = JSON.parse(data)
document.body.removeAttribute('my-attribute')

// idea 1 - use JOI (or similar) at the router level
let params = {
  query: {
    limit: Joi.number().integer().min(1).max(100).default(10)
  }
}
server.get("/horse", enforceParams(params), controller.myRoute)

// idea 2 - use JOI (or similar) at the controller level
async function myRoute(req, res) {

Trying Flow on my node.js code…Let’s see how this goes

Finding the getting started guide:

1. google flow
2. click “getflow.com”
3. was something else
4. google flow javascript
5. found flowtype.org
6. Click “get started” and landed here https://flowtype.org/docs/getting-started.html#_

// no types
function getFields(fields) {
   return fields.reduce((prev, curr) => (prev[curr] = curr, prev), {})
}

// no return type
function getFields(fields: Array<string>) {
   return fields.reduce((prev, curr) => (prev[curr] = curr, prev), {})
}

// catch any errors in the promise and either forward them to next(err) or ignore them
const catchErrors = fn => (req, res, next) => fn(req, res, next).catch(next)
const ignoreErrors = fn => (req, res, next) => fn(req, res, next).catch(() => next())

// wrap my routes in those helpers functions to get error handling
app.get('/sendMoney/:amount', catchErrors(sendMoney))

// use our ignoreErrors helper to ignore any errors in the logging middleware
app.get('/doSomethingElse', ignoreErrors(logSomething), doSomethingElse)

// rely on try/catch around the awaited Promise
async function doSomething() {
    try { 
        let data = await getData()
    } catch (err) {
        console.error(err)
    }
}

// add a catch handler
