CLARK's eslint-config for Ember.js
# With TypeScript
yarn add -D eslint @clark/eslint-config-ember @clark/eslint-config-node typescript @clark/eslint-config-ember-typescript
# Without TypeScript
yarn add -D eslint @clark/eslint-config-ember @clark/eslint-config-node
Ember projects consist of up to three different types of JS source files:
Apps
app
tree or src
tree (Module Unification) and tests
tree /
dummy appember-cli-build.js
or config/environment.js
Addons
addon
tree or src
tree (Module Unification) and tests
tree /
dummy appapp
tree, which usually re-export files from addon
index.js
Node.js and Ember source files obviously have fundamentally different linting
requirements. The official Ember blueprint currently solves this by adding
overrides
for Node files and just using a single .eslintrc.js
.
We have found this to be very brittle and hard to maintain on the long run. A detailed argument can be found in this Pre-RFC #450 "change eslint blueprint".
While the world is still waiting for eslint/rfcs#9 to bring a new
and better config system to the table, we have found it much more feasible to
create multiple root: true
.eslintrc.js
files instead of using
overrides
.
Remember to create .eslintignore
files! Otherwise eslint
might seemingly
hang indefinitely, because it tries to lint your huge bundled dist files or
node_modules
.
Furthermore, we recommend to remove any linting integration from ember-cli
.
So this means uninstalling ember-cli-eslint
and installing eslint
instead.
The default lint:js
task (eslint .
) is sufficient. When you want to use
TypeScript, e.g. via
@clark/eslint-config-ember-typescript
you
have to update it to eslint --ext ts,js .
.
You can also remove any other pre-installed eslint dependencies, like
eslint-plugin-ember
and eslint-plugin-node
. They are included in our
configs.
