How to config ESLint for React on Atom Editor

Question

In Atom Editor I installed the following plugins

1. linter
2. linter-eslint

It seems they don't recognize the JSX syntaxis.

I have it working on the command line but had to use other plugins like esprima-fb and eslint-plugin-react. Looks like there are no such plugins for Atom Editor and would like to know if anyone of you knows a way to hack around this.

To get Eslint working nicely with React.js:

1. Install linter & linter-eslint plugins
2. Run npm install eslint-plugin-react
3. Add "plugins": ["react"] to your .eslintrc config file
4. Add "ecmaFeatures": {"jsx": true} to your .eslintrc config file

Here is an example of a .eslintrc config file:

{
    "env": {
        "browser": true,
        "node": true
    },

    "globals": {
        "React": true
    },

    "ecmaFeatures": {
        "jsx": true
    },

    "plugins": [
        "react"
    ]
}

I am using Eslint v1.1.0 at the moment.

Side note: I had to install both eslint and eslint-plugin-react as project dependencies (e.g., npm install eslint eslint-plugin-react --save-dev). Hopefully this helps.
