Some default steps to follow when I start a new Ember app. Most of this is taken from Sergio Arbeo's post on the Dockyard blog, but this is a bit more streamlined and suited to my usage:

1. Remove unnecessary packages:

   npm uninstall --save-dev \
       ember-welcome-page \
       ember-data \
       ember-cli-eslint \
       ember-cli-template-lint

2. Add lower level packages:

   npm i --save-dev \
       ember-template-lint \
       eslint \
       prettier \
       eslint-plugin-prettier \
       eslint-config-prettier \
       husky \
       lint-staged \
       concurrently

3. Add configs to package.json:

   {
       ...<other stuff>...
       "prettier": {
           "printWidth": 100,
           "singleQuote": true,
           "useTabs": false
       },
       "husky": {
           "hooks": {
               "pre-commit": "lint-staged"
           }
       },
       "lint-staged": {
           "*.js": ["eslint —fix"],
           "*.hbs": ["ember-template-lint"]
       }
   }

4. Remove render from application.hbs

5. Update .eslintrc to use the prettier plugin and extend from its rules

6. Update .eslintrc to use plugin:ember/octane instead of plugin:ember/recommended.
