How to delete .eslintcache file in react?
ReactjsReactjs Problem Overview
I'm new to React. I have a problem I can not solve. I have an ".eslintcache" file, which was created for me automatically as soon as I created a new app in React using "create-react-app". I do not know why I have this file. I tried to delete it but it always comes back. I ran this command - "npm uninstall -g eslint --save" - to delete eslint's directory but it does not help. I do not know how to handle it, I did not find a solution to it, I would be happy to help.
Reactjs Solutions
Solution 1 - Reactjs
It is part of the CRA bundle. I'd recommend just adding it to the .gitignore
file if it isn't in there already.
From the ESLint docs:
> Store the info about processed files in order to only operate on the changed ones. The cache is stored in .eslintcache by default. Enabling this option can dramatically improve ESLint's running time by ensuring that only changed files are linted.
Solution 2 - Reactjs
It seems as new issue in React App (this issue opened on Nov 27, 2020)
Put .eslintcache
in .gitignore
also do:
git rm -rf --cached .eslintcache
git add .
git rm
: remove files from working tree ...
-r
: recursive removal in case of a directory name ...
-f
or -force
: Override the up-to-date check.

Solution 3 - Reactjs
This file is part of the new version of create-react-app package, you can't avoid it to be added, just like other files being added. This is the bundle.
Solution 4 - Reactjs
This is part of the new version in react. I also had files "reportWebVitals" and "setupTests", I deleted them and everything works properly.
With "reportWebVitals" you can track real user performance on your site. And with "setupTests" you are Initializing Test Environment
this feature is available with [email protected] and higher
I do not need these properties, just deleted them and that's it, the eslintcache can not be deleted is part of the bundle.
Solution 5 - Reactjs
I faced the problem, tried putting .eslintcache
in .gitignore
and implement the command git add .
but was not enough, because you should do git add .
after every change in your code, and that's not sence at all of course, this is not a clean workround anyway.
So, simply i downgraded the react-scripts
to @4.0.0
, and that problem disapeared completely
I think the react-scripts@4+
isn't stable yet
Solution 6 - Reactjs
I ended up writing a custom plugin to delete the .eslintcache
before each watch compile:
var exec = require("child_process").execSync;
module.exports = class ESLintClearPlugin {
constructor(options) {
this.options = options;
}
apply(compiler) {
compiler.hooks.watchRun.tap("ESLintClearPlugin", () => {
exec("del .eslintcache");
});
}
};
Then you use it in your webpack config:
const ESLintClearPlugin = require("./pathtofile");
// webpack config
plugins: [new ESLintClearPlugin()]
