No control over order of remotes().before hook

[bitmage]

I have two hooks attached to remotes().before, like so:

app.remotes().before('*.*', test1)
app.remotes().before('Company.someAction', test2)

Regardless of which order I put them in, test2 always runs before test1. What is the intended order of operation of these hooks? Should I be able to control it by changing the order I define them in?

I did some more testing. The order is predictable as long as I have multiple hooks with the *.* pattern. As soon as I introduce a more specific pattern though, it runs before any of the general hooks.

To work around this, I've implemented a custom 'before' hook that intercepts everything with *.* and lets me do my own matching.

const _ = require('lodash')
const matchOrStar = ([p, s]) => p === '*' || p === s
const match = (pattern, string) => {
 if (!~string.indexOf('.')) return false
 const matchup = _.zip(
 pattern.split('.'),
 string.split('.')
 )
 return _.every(matchup, matchOrStar)
}

// Define a custom before hook because loopback changes the ordering based on the specificity of the pattern.
// We don't want that!
const before = (pattern, cb) => {
 app.remotes().before('*.*', (ctx, next) => {
 match(pattern, ctx.methodString) ? cb(ctx, next) : next()
 })
}

before('*.*', lookupAccountId)
before('Company.analysis', cacheStuff)

This works, but it's pretty disapointing that I have to jump through these hoops.

The order is predictable as long as I have multiple hooks with the . pattern. As soon as I introduce a more specific pattern though, it runs before any of the general hooks.

I believe this is by design: we run more specific patterns first, before running general patterns like *.*. See strong-remoting's lib/remote-objects.js

@raymondfeng @ritch could you please confirm?

If you want to setup a "before" hook that's always executed before any other "beforeRemote" hooks, then you should use a custom strong-remoting phase as explained here: https://loopback.io/doc/en/lb3/Using-current-context.html#use-a-custom-strong-remoting-phase
