SublimeText3 configures react syntax verification

SublimeText3 is a cross-platform code editor software. SublimeText3 can both write code and edit text. It is an essential tool for programmers. The following column sublime usage tutorial will introduce you to the SublimeText3 configuration of react syntax verification. I hope it will be helpful to friends in need!

1. Install nodejs

2. Open the terminal and install the eslint verification package and react verification plug-in package :

npm install -g eslint
npm install -g eslint-plugin-react

3. Install the plug-in in Sublime:

SublimeLinter
SublimeLinter-contrib-eslint

4. Run eslint --init

Configure the initialization file according to the prompts and generate the .json format

5. Configure .eslintrc

.eslintrc.json
