Slow initial build

[mmahalwy]

The build is really really slow since we included this:

Slowest Trees                                 | Total
----------------------------------------------+---------------------
EslintValidationFilter                        | 31237ms
EslintValidationFilter                        | 11729ms

This is the product of many things at play, some are solvable some are not.

• Caching filter can be used
• Closer integration with Ember to not require JSHint

ESLint is however slower than JSHint, the advantages are flexibility.

My time is fairly limited at the moment and although this is a crappy response, it is a reality.

I'm happy to accept pull requests until I get some more time to resolve.

Hey @jonathanKingston sounds good - perhaps it'd be useful to have the initial build not run eslint but rebuilds do? Perhaps you can guide me really quickly where the API for rebuilds is and I will go at it :)

Hi, I was wondering if there had been any work done on this? We are running into similar issues with slow build times. We want to be able to run eslint in our test suite but not on the initial build of the app. Is there anyway to disable linting on the build?

@hjbuchanan unfortunately that is currently not possible 😕

[hjbuchanan]

@Turbo87 thanks for the quick comment back--would you all be willing to accept a PR that made those changes?

[Turbo87]

@hjbuchanan sure, we are always happy to review and merge PRs! what specific changes are we talking about though? only running ESLint on demand when running tests is unfortunately impossible or at least very difficult to implement.

There is an option called hinting that this plugin should respect. If it is false, it should not run. You can toggle this in your ember-cli-build.js by detecting the environment.

ex:

module.exports = function(defaults) {
  var app = new EmberApp(defaults, {
    hinting: EmberApp.env() === 'test',
