Use eslint for automatic formatting

Sometimes your front-end project uses eslint, which has automatic formatting configuration. We want to use the project’s own eslint configuration. We can use the format of eslint when saving automatically.

Let’s install the eslint plug-in first

Then set it in vscode

"editor.codeActionsOnSave": {
        "source.fixAll.eslint": true
 }

Add this configuration. In this way, the eslint configuration of the project itself will be used when saving.
