Rich Trott d7aa8fa088 tools: update ESLint to version 2.1.0 Update ESLint to 2.1.0. ESLint has a number of potentially-useful new features but this change attempts to be minimal in its changes. However, some things could not be avoided reasonably. ESLint 2.1.0 found a few lint issues that ESLing 1.x missed with template strings that did not take advantage of any features of template strings, and `let` declarations where `const` sufficed. Additionally, ESLint 2.1.0 removes some granularity around enabling ES6 features. Some features (e.g., spread operator) that had been turned off in our configuration for ESLint 1.x are now permitted.

estraverse-fb

Drop-in for estraverse that enables traversal over React's JSX and Flow nodes using monkey-patching technique.

You can use estraverse-fb in two possible ways:

by default, you just require it and it injects needed keys into your installed version of estraverse (it's installed automatically if you don't have it yet):

var estraverse = require('estraverse-fb');
/* same as:
    require('estraverse-fb');
    var estraverse = require('estraverse');
*/

estraverse.traverse(ast, {
    enter: ...,
    leave: ...
});

alternatively, you can use it manually for selected traversals:

var jsxKeys = require('estraverse-fb/keys');

estraverse.traverse(ast, {
    enter: ...,
    leave: ...,
    keys: jsxKeys
})
