We may not always have binstubs relative to the directory we are running the rake task from. The particular case for this is with a mountable Rails engine and dummy app that is created to test it. This sets all the tasks up to run under an `app` namespace in railties/lib/rails/tasks/engine.rake This change resolves a problem whereby running `app:yarn:install` would have no effect as it would try to run in the plugins bin directory rather than the test/dummy/bin. This also means that it installs from test/dummy/package.json and into test/dummy/node_modules which is behaviour consistent with a normal Rails app. On a rails engine: ``` ➜ tmp rails plugin new rails-plugin --mountable ➜ tmp cd rails-plugin ``` Before this change: ``` ➜ rails-plugin rake app:yarn:install ➜ rails-plugin ``` After this change: ``` ➜ rails-plugin rake app:yarn:install yarn install v1.9.4 info No lockfile found. [1/4] 🔍 Resolving packages... [2/4] 🚚 Fetching packages... [3/4] 🔗 Linking dependencies... [4/4] 📃 Building fresh packages... ✨ Done in 0.07s. ``` When this change is ran against a normal rails install there is not a behavioural change: ``` ➜ tmp rails new full-app ➜ tmp cd full-app ➜ full-app git:(master) ✗ rake yarn:install yarn install v1.9.4 info No lockfile found. [1/4] 🔍 Resolving packages... [2/4] 🚚 Fetching packages... [3/4] 🔗 Linking dependencies... [4/4] 📃 Building fresh packages... ✨ Done in 0.09s. ```
