eslint-ts-naming-conventions
Config generator for typescript-eslint plugin @typescript-eslint/naming-convention rule.
This package helps to keep code naming conventions up to date as your projects grow. If you use eslint shared configs you can update it to share your updates among many projects but still keep the small differences from one project to another different.
It generates a .js file containing the @typescript-eslint/naming-convention rule definition ready to be extended in your .eslintrc.js file.
Allows full customization upon its default config.
Table of contents:
Installation
$ yarn install eslint-ts-naming-conventions
Usage
You can set how your rule configuration should be
import eslintTsNamingConventions from 'eslint-ts-naming-convention'
await eslintTsNamingConventions({
reportLevel: 'warn',
filePath: '.eslint-ts-naming-conventions.js',
// Here you can set variables shared across multiple configs for the rule
general: {
functionPrefixes: ['create', 'retrieve', 'search', 'delete'],
booleanPrefixesLC: ['is', 'should', 'enable', 'require'],
booleanPrefixesUC: ['IS', 'ENABLE'],
arraySuffixesLC: ['s', 'List'],
arraySuffixesUC: ['S', 'LIST'],
},
// Here you provide your own configs to overwrite defaults as you like
specific: [
{
selector: 'variable',
format: ['camelCase', 'PascalCase', 'UPPER_CASE'],
leadingUnderscore: 'allow',
},
]
)
The above code will generate the .eslint-ts-naming-conventions.js file whose content will look like:
module.exports = {
rules: {
"@typescript-eslint/naming-convention": [
"warn",
{
"selector": "variable",
"format": [
"camelCase",
"PascalCase",
"UPPER_CASE"
],
"leadingUnderscore": "allow"
},
{
"selector": "variable",
"types": [
"boolean"
],
"format": [
"camelCase",
"PascalCase",
"UPPER_CASE"
],
"custom": {
"match": true,
"regex": "^[is|should|enable|require|force|IS|ENABLE]"
}
},
{
"selector": "variable",
"types": [
"array"
],
"format": [
"camelCase",
"PascalCase",
"UPPER_CASE"
],
"custom": {
"match": true,
"regex": "[s|List|S|LIST]$"
}
},
{
"selector": "function",
"format": [
"camelCase"
],
"custom": {
"match": true,
"regex": "^[create|retrieve|search|delete]"
}
},
]
}
}
Finally in your .eslintrc.js file you extend your fresh generated config:
module.exports = {
parserOptions: {
project: './tsconfig.json',
tsconfigRootDir: __dirname,
},
extends: './.eslint-ts-naming-convention.js',
}
