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-dev

Then, 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:
  * @typescript-eslint/no-unused-expressions:
    - The TSLint optional config "allow-new" is the default ESLint behavior and will no longer be ignored.
  * prefer-arrow/prefer-arrow-functions:
    - ESLint does not support allowing named functions defined with the function keyword.
  * camelcase:
    - Leading undescores in variable names will now be ignored.
  * no-underscore-dangle:
    - Leading and trailing underscores (_) on identifiers will now be ignored.
  * no-redeclare:
    - ESLint does not support check-parameters.
  * @typescript-eslint/no-unused-vars:
    - Please read the following article as the rule behaviour may change on the short term: https://github.com/typescript-eslint/typescript-eslint/issues/1856
  * @typescript-eslint/strict-boolean-expressions:
    - String, number, enum, and mixed union types are now forbidden.
  * class-methods-use-this:
    - allow-public methods will no longer be ignored.
