Official Neo Financial ESLint configuration
This package includes 4 different ESLint configs:
config-backend
config-frontend
config-backend-next
config-frontend-next
The next
versions include some rules that are being considered for inclusion in future versions of the base config. The next
configs also require you to specify the project
setting in parserOptions
for TypeScript projects. The will make ESLint run slower in TypeScript projects.

The arrows from left to right illustrate which configs are extended by another config.
npm install --save-dev eslint-config-neo
You can also install a specific version of the package by appending the version tag. For example, to install version 1.0.0
npm install --save-dev eslint-config-neo@1.0.0
npm install -D eslint prettier lint-staged husky typescript
Add .eslintrc
to project root
{ "extends": "eslint-config-neo/config-backend" }
Use eslint-config-neo/config-frontend
for frontend projects
parserOptions
with next
configs
If you're using one of the next
configs you must set the project
option to include all of your tsconfig.json
files:
{ "extends": "eslint-config-neo/config-backend", "parserOptions": { "project": ["tsconfig.json", "test/tsconfig.json"] } }Make Prettier Config File
Add .prettierrc
to project root
{ "printWidth": 120, "singleQuote": true }
Optional: If there are any files you want to exclude from Prettier add .prettierignore
to project root
Add .editorconfig
to project root
# http://editorconfig.org root = true [*] charset = utf-8 end_of_line = lf indent_size = 2 indent_style = space insert_final_newline = true max_line_length = 120 [*.md] max_line_length = 0 trim_trailing_whitespace = false [COMMIT_EDITMSG] max_line_length = 0
Add the engines field to package.json
"engines": { "node": "^12.0.0" }
Add scripts for linting and formatting to package.json
"scripts": { "lint": "eslint .", "format": "prettier --write \"**/*.{ts,tsx,js,json,graphql,md}\"", "format:check": "prettier --debug-check \"**/*.{ts,tsx,js,json,graphql,md}\"" }
Add a precommit hook to package.json
to automatically lint and format any files staged for commit
"husky": { "hooks": { "pre-commit": "lint-staged" } }, "lint-staged": { "concurrent": false, "linters": { "*.{ts,tsx,js}": [ "eslint --quiet", "git add" ], "*.{ts,tsx,js,json,graphql,md}": [ "prettier --write", "git add" ] } }
If you've added Prettier to an existing project you will want to format all the code. The precommit hook only updates files that have been changed and staged for commit. To format the entire codebase run
npm run format
eslint
version 8.26.0
or highereslintrc
Should I override the rule X? I don't like it.
No. If you want to do this, you have to ask the team. If a rule really doesn't make sense then we should remove or disable it.
Can I disable the rule on one line in my code, I have a good reason.
Yes. That's ok. Use a single-line disable.
