eslint-plugin-no-arrow-this
Proposal
This is a eslint plugin for warning "this" keyword inside of arrow functions. The key is about to get rid of using this
in sort of global
context.
For example, you have a code with regular function:
(function () {
var me = this;
console.log(me);
}.bind(123))();
And then, somehow, may be after re-factoring, you will change that regular function to arrow function:
(() => {
var me = this;
console.log(me);
}).bind(123)();
So, starting from that pont me
no longer follows to the binded context, and receives global
or window
instead.
This plugin will help you to find this conditions.
Example .eslintrc configuration
installation
$ npm i eslint-plugin-no-arrow-this
typical config for everything
"plugins": [
// ... other plugins
"eslint-plugin-no-arrow-this"
],
// ... other stuff
"rules": {
// ... other rules
"no-arrow-this/no-arrow-this": "warn"
}
So far here you will receive warning on eslint
.
