Algoan ESLint configuration shared for NodeJS projects written in TypeScript and using prettier. It is the ESLint equivalent for @yelloan/tslint rules.
First, install this module running:
npm install @algoan/eslint-config --save-devThen, create a .eslintrc.json file:
{
"extends": "@algoan/eslint-config"
}In your package.json file, add a script:
{
"lint": "eslint src/**/**.ts"
}Using the tsling-to-eslint-config script:
8 ESLint rules behave differently from their TSLint counterparts:
