[jscodeshift](https://github.com/facebook/jscodeshift) find api automatically generated from code

Checkout the api in this [playground](https://rajasegar.github.io/ast-finder/)

Read the [introductory blog post](http://hangaroundtheweb.com/2019/12/ast-finder-finding-ast-nodes-from-code/) for more details.

## Usage

```js

import { findQuery } from 'ast-node-finder';

import { parse } from 'recast';

const source = `foo.bar.baz(1,2,3)`;

const ast = parse(source);

// Pass the node from ast and get the find api

console.log(findQuery(ast.program.body[0].expression));

```

### Output

```js

root.find(j.CallExpression, {

  callee: {

    object: {   object: { name: 'foo' },

    property: { name: 'bar' }

  },

  property: { name: 'baz' }

  }

})

.forEach(path => {

  // Manipulate the path (node) here

});

```
