TypeScript ESLint doesn't work with Airbnb configuration #2049

iwis · 2020-05-20T11:01:32Z

I installed https://github.com/typescript-eslint/typescript-eslint/ then performed steps from https://www.npmjs.com/package/eslint-config-airbnb-typescript (without React). I got the following errors:

It is probably again a problem with a documentation. I also added issue here: iamturns/eslint-config-airbnb-typescript#93

yoyo930021 · 2020-05-20T13:03:46Z

If you install eslint package?

iwis · 2020-05-20T13:18:11Z

Using yarn or node, or it doesn't matter? And which version of eslint?

iwis · 2020-05-20T13:29:21Z

I run: npm install yarn add -D eslint. And I get:

yarn eslint . --ext .ts works now. I do not know where was the problem. I think that I did everything according to the documentations.

bradzacher · 2020-05-20T16:20:55Z

A lot of the packages just assume two things:

you've already got typescript installed.
you've already got eslint installed.

The thinking being that you've already got a scaffold built or are just starting a project, thus you already have installed typescript. It's rare that the setup process is:
create folder -> install linting tooling -> attempt lint.
usually it's:
create folder -> install typescript (and other frameworks like react) -> install linting tooling -> write code -> attempt lint.

Thus they omit the typescript installation step.

Similarly it's a generally assumed thing within the eslint world that you have already installed eslint. The assumption being that the setup step is:
setup codebase -> install eslint -> want better linting for X -> install plugin/config for X.
instead of:
setup codebase -> install plugin/config for X -> lint.

All of the plugins, parsers and configs have a peerDependency on eslint on purpose (that's literally what peer deps are designed for).

I have installed TypeScript at the beginning using: npm install typescript@3.7.5 --save-exact

I also installed ESLint using: yarn add -D eslint @typescript-eslint/parser @typescript-eslint/eslint-plugin

My process was:

write code using TypeScript (thus I had TypeScript - firstly it was installed globally, but now it is installed locally)
install "TypeScript ESLint"
install Airbnb configuration

I performed steps no. 2-3 again to check if I will have a problem:

npm init -y
npm install typescript@3.7.5 --save-exact
TypeScript 3.7.5 is the newest version supported by TypeScript ESLint 2.34
yarn add -D eslint @typescript-eslint/parser @typescript-eslint/eslint-plugin
I have found this command on: https://github.com/typescript-eslint/typescript-eslint/tree/master/packages/eslint-plugin
I have checked in node_modules folder that it contains ESLint 7.0.0
npm install eslint-config-airbnb-typescript eslint-plugin-import@^2.20.1 @typescript-eslint/eslint-plugin@^2.24.0 --save-dev
I have found this command on: https://www.npmjs.com/package/eslint-config-airbnb-typescript
I believe that ESLint was removed during this step but I am not sure because I don't use npm often.
Commands eslint --ext .ts and yarn eslint . --ext .ts don't work now.
npm install yarn add -D eslint
I added .eslintrc.js file with the following content:

module.exports = {
  extends: ['airbnb-typescript/base'],
  parserOptions: {
    project: './tsconfig.json',
  },
};

Now yarn eslint . --ext .ts works.

Here is the result of each step:
