eslint-config-opengovsg v2.0.6

eslint-config-opengovsg

Goal

The goal of this package is to provide reasonable defaults for most common scenarios, so that developers can start building without worrying about linting configurations.

Explanation

ESLint is a tool to "find and fix problems in your JavaScript code" (from https://eslint.org/). We use ESLint to help us write better code. However, we do not want to invest efforts into the fine-tuning of detailed configurations, as those efforts can be better invested into building other things.

As a result, we will NEVER have self-defined opinions in the library, which means rules section should not exist in the configs. Instead, only recommended rule sets from the biggest linting libraries (e.g. eslint:recommended) will be used. Essentially:

1. We fully trust the community out there to maintain a reasonable set of recommended rules, so that most common error-prone patterns are covered
2. When something really does not make sense in recommended, there are 2 options:
   • influence and change the upstream recommended rule set
   • or do overrides in .eslintrc in our own repositories, NOT here. If a rule does not make sense to the broader community thus cannot enter the recommended rule set, it would not make sense to be here either.

Usage

To install (including all the peer dependencies as devDependencies):

npx install-peerdeps --dev eslint-config-opengovsg

Depending on the usage, put one of the following into .eslintrc:

• TypeScript (yep we use TypeScript by default in OGP: {"extends": ["opengovsg"]})
• React ({"extends": ["opengovsg", "opengovsg/react"]} or {"extends": ["opengovsg/javascript", "opengovsg/react"]})
• Pulumi ({"extends": ["opengovsg", "opengovsg/pulumi"]})
• JavaScript (in case you really do not need TypeScript: {"extends": ["opengovsg/javascript"]})
