Transforming a file with a template literal that contains a non-ASCII character will not work.
Any two-byte character seems to bump rightBackTickPos
(determined by node.loc.end
) 1 higher than what this assert in recast
's util.fixTemplateLiteral expects.
The parser seems to count the position of multibyte chars several times in a way that recast
doesn't handle properly. At first sight the parser chosen by jscodeshift
seems to be babel-core
.
Example of a file that won't be transformed:
import React from 'react';
const Foo = React.createClass({
render() {
return <div>{`æøåß`}</div>;
},
});
export default Foo;
Output:

I'm probably not going to bother to look any more at this, especially if I'm the only one having this issue.
If you're reading this in search for a quick and dirty fix, you can try to comment out the assert in recast
and hope for the best. (That worked out just fine for me, but your milage may vary.)
It would be nice to pick up the specific sort order defined in .eslintrc if not provided through the CLI options before falling back to the airbnb order.
Let's take this scenario into consideration:
(...)
class AwesomeComponent extends React.Component {
(...)
}
(...)
class Test extends AwesomeComponent {
(...)
}
When using e.g. sort-comp
it skips components extending other component extending React.Component.
My temporary fix was changing:
// Finds all classes that extend React.Component
const findReactES6ClassDeclaration = path => {
const componentImport = findReactComponentName(path);
const selector = componentImport
? {
superClass: {
type: 'Identifier',
name: componentImport,
},
}
: {
superClass: {
type: 'MemberExpression',
object: {
type: 'Identifier',
name: 'React',
},
property: {
type: 'Identifier',
name: 'Component',
},
},
};
return path
.find(j.ClassDeclaration, selector);
};
to
// Finds all classes that extend React.Component
const findReactES6ClassDeclaration = path => {
const componentImport = findReactComponentName(path);
const selector = componentImport
? {
superClass: {
type: 'Identifier',
name: componentImport,
},
}
: {
superClass: {
type: 'Identifier',
name: 'AwesomeComponent',
},
};
return path
.find(j.ClassDeclaration, selector);
};
In a comment in sort-comp, I noticed the following comment:
NOTE: only works on React.createClass() syntax, not ES6 class.
It would be really lovely if this worked with ES6 classes. 😺

I use babel-loader with this config:
['react', 'stage-1', ["env", { "targets": { "chrome": 56 }}]]
but as jscodeshift --babel
flag defaults to true, I think this shouldn't be an issue.
The current version on NPM is 2.0.0 and the repo is at 4.0.0. Can we publish the current version? I want to use the sort-comp
transform without having to clone and build the repo.
I have some components that transform incorrectly as blow:

My component example is
import React, { Component, PropTypes } from 'react';
import Message from './Message';
if (process.env.BROWSER) {
require('./style/index.scss'); // eslint-disable-line
}
...
related code
function addPropTypesImport(j, root) {

Files are simply skipped due this code:
root
.find(j.CallExpression)
.filter(p => isRequire(p, coreModuleName))
In order to workaround es6 imports there should be something like:
root
.find(j.ImportDeclaration)
I'm dumb in AST, so I can't make a PR.
not sure why but all my code is being skipped over without explantion
this is how I call the command
jscodeshift -t react-codemod/transforms/create-element-to-jsx.js dealroom/assets/jsx/core/Dialog.js

It looks like the create-element-to-jsx
transform silently throws away comments within React.createElement
calls. Ideally, it should find some way to preserve the comments, or maybe give an error so I can fix those files manually, but if that's too hard or out of scope, I think the behavior should at least be documented.
For example, if you run it on this file:
import React from 'react';
const render = () => {
return React.createElement('div', {
className: 'foo', // This is an important comment.
});
};
It produces this:
import React from 'react';
const render = () => {
return <div className="foo" />;
};
When running this command:
jscodeshift -t ~/react-codemod/transforms/class.js filename.jsx
For the files that have mixins in them I get:
filename.jsx: 'Component' was skipped because of mixins.
although the component is defined with React.createClass()
and the script should create ES2015 classes.
How should I still use the script and work around mixins?
I want to leave mixins and use them with a 3rd party lib.
When i try to convert components that have mixins in them they get skipped, can i somehow ignore that and still convert components to classes?
Hi!
So I ran into an issue where running the mod when getInitialState
is an arrow
function it breaks (code has been changed due to corporate IP...):
export default React.createClass({
displayName: 'MyComponent',
getInitialState: () => ({
stateThingOne: 'beep',
stateThingTwo: 'boop'
}),
// ...
})
The error message would be this:

Is there a way to see why files are being skipped? It seems like no matter what transform I use, my .js file will be skipped. Thanks.
This class that is using class property initializers
import React, { PropTypes } from 'react';
export default class StringControl extends React.Component {
handleChange = (e) => {
this.props.onChange(e.target.value);
};
render() {
return <input type="text" value={this.props.value || ''} onChange={this.handleChange} />;
}
}
StringControl.propTypes = {
onChange: PropTypes.func.isRequired,
value: PropTypes.node,
};
gets transformed to:
import React, { PropTypes } from 'react';
export default function StringControl(props) {
return <input type="text" value={props.value || ''} onChange={this.handleChange} />;
}
StringControl.propTypes = {
onChange: PropTypes.func.isRequired,
value: PropTypes.node,
};
It should not.

I saw the same failures when running npm install
locally.
Looking at the build history it appears that 84ef7b7 is good but 5093980 even though the latter didn't introduce any changes into class.js.
I thought maybe it was an issue with the version of jscodeshift I had so I installed 0.3.28 which is what the last passing build installed. That did not fix the situation so I'm guessing it's some other dependency (or sub-dependency) that's causing the issue.
We never shipped it in React.addons. It should be used from require('react-addons-shallow-compare')
.
(previously filed as facebook/react#4315).
I have many components for which prop-types transformation happening correctly, but for other components its failing with following error
TypeError: Cannot read property 'name' of undefined

One such component code example is
import React from 'react';
import Link from '../Link';
const Breadcrumb = ({ links }) => (
<div itemType="http://schema.org/breadcrumb" itemProp="breadcrumb">
......
</div>
);
Breadcrumb.propTypes = {
links: React.PropTypes.arrayOf(
React.PropTypes.shape({
title: React.PropTypes.string.isRequired,
href: React.PropTypes.string
})
).isRequired
};
export default Breadcrumb;
Help!
Would anyone be interested in an option for the pure-component transform that would destructure the props where possible - i.e. when there's no {...this.props}
or doStuff(this.props)
and only keys of this.props
are used?
I would be down to open a PR if so.
So
render() {
const { prop1 } = this.props;
return <div prop1={prop1} prop2={this.props.prop2} />;
}
Would become
({ prop1, prop2 }) => <div prop1={prop1} prop2={prop2} />;
Should not add semicolons like below:
- import React, { Component, PropTypes } from 'react'
+ import React, { Component } from 'react';
+ import PropType from 'prop-types';
A component can only be converted into a stateless component if it does not use refs on its children. The current codemod does not check for it.
Still amazed by these codemods, but this could be a great improvement...
I'm trying to run the PropTypes transformation on my code base but the only file it (wrongly) updates is a file containing a single propType specification:
- import { PropTypes } from 'react';
+ import 'react';
export const SEPARATOR = 'separator';
export default {
type: PropTypes.oneOf([SEPARATOR]),
value: PropTypes.any,
label: PropTypes.string,
};
All my other files are simply ignored (they are very basic components):

What happens?
I'm just here to say thanks for this! I'm really amazed at how well it works and I was pleasantly surprised that it doesn't just force an import of create-react-class
but it will actually codemod to ES6 class (with public class fields) if it's not using mixins 🎉 thanks!

When a file being transformed requires styles like this but uses import
statements, the transform does not create the import PropTypes from 'prop-types';
Did a dry run and got the following message:
Overview
was skipped because of deprecated API calls. Remove calls to getDOMNode, isMounted, replaceProps, replaceState, setProps in your React component and re-run this script.
I do indeed use replaceState, but the context is history.replaceState (https://developer.mozilla.org/en-US/docs/Web/API/History_API), not React, so I believe there should not be a problem, the function names just happen to be the same.
jscodeshift -t transform.js <path> --printOptions='{"quote":"single"}'
is not working
MyComponent.jsx:
const React = require("react");
const MyComponent = React.createClass({
render: function () {
return (
<label title={(true ? "T1" + "•" : "T2") + "T3"} />
);
},
});
jscodeshift -t ../../react-codemod/transforms/class.js MyComponent.jsx
output:
const React = require("react");
class MyComponent extends React.Component {
render() {
return (
<label title={(((true ? "T1" + "•" : : 2") ))+ "T3"} />
);
}
}
Given a PropTypes
import that looks like this:
const {
PropTypes: {
shape,
bool,
number,
string
}
} = React
the prop-types
codemod will insert import PropTypes from 'prop-types';
but will remove the destructuring assignment completely, leaving shape
, bool
, number
, and string
undefined.
Is there a way I can see why my files are being skipped on the create-element-to-jsx
transform? I tried using astexplorer but had no luck. Any advice would be appreciated. Thanks.
The output shows:

Invalid
Looks like regular expression values in this eslint property are ignored. For example:
"react/sort-comp": [2, {
order: [
"/^render/",
"/^on/",
"everything-else"
]
}]
gives the same output as
"react/sort-comp": [2, {
order: [
"everything-else"
]
}]
The create-element-to-jsx transform attempts to make replacements like this:
- return React.createElement(Constructor, props);
+ return <Constructor />;
Expected:
- return React.createElement(Constructor, props);
+ return <Constructor {...props} />;
I noticed that this will transform React.createElement
, but not React.DOM.div
, which is just a convenience wrapper. I have a large codebase that I'm going to need to transform very soon and it's all using React.DOM.div
(or span
, a
, etc). It sounds like it would be easy to make that work the same as React.createElement
. What do you think?

Before:
let WorkspaceItemView = React.createClass({
displayName: 'WorkspaceItemView',
getInitialState() {
return {
workspaceItemManager: this._getWorkspaceItemManager(this.props.id),
workspaceItemStore: this._getWorkspaceItemStore(this.props.id)
};
},
});
After: (that's how it works now)
class WorkspaceItemView extends React.Component {
static displayName = 'WorkspaceItemView';
state = {
workspaceItemManager: this._getWorkspaceItemManager(this.props.id),
workspaceItemStore: this._getWorkspaceItemStore(this.props.id)
};
}
But it should be this:
class WorkspaceItemView extends React.Component {
static displayName = 'WorkspaceItemView';
constructor(props) {
super(props);
this.state = {
workspaceItemManager: this._getWorkspaceItemManager(this.props.id),
workspaceItemStore: this._getWorkspaceItemStore(this.props.id)
};
}
}
Wasn't sure if I should report this here or with the jscodemod
folks. I ran npm -g list jscodeshift
which installed the latest jscodeshift
, then tried running:
jscodeshift -t ~/Downloads/react-codemod-master/transforms/pure-render-mixin.js ./ -d -p
Which gave me the following error:

Possible separate issue (unsure): I tried running it on a specific file, ./Components/App.jsx

For the record, I'm on node v6.7.0, React 15.3.2, and I just downloaded react-codemod
.
Hey there!
So our codebase has a component like this
import React, { PropTypes } from 'react';
import classnames from 'classnames';
const propTypes = {
children: PropTypes.node,
className: PropTypes.string,
};
const Accordion = ({ children, className, ...other }) => {
const classNames = classnames('bx--accordion', className);
return (
<ul className={classNames} {...other}>
{children}
</ul>
);
};
Accordion.propTypes = propTypes;
export default Accordion;
The codemod currently breaks on the destructured parameter - if I swap it over to
const Accordion = props => {
const { children, className, ...other } = props;
const classNames = classnames('bx--accordion', className);
return (
<ul className={classNames} {...other}>
{children}
</ul>
);
};
The codemod runs perfectly fine and outputs as expected.
The error is below
ERR components/Accordion.js Transformation error
TypeError: Cannot read property 'name' of undefined

Why does the script convert
this.refs.injectButton.getDOMNode().focus();
into
React.findDOMNode(this.refs.injectButton).focus()
My understanding of the changes to refs
is that the original code could be transformed to
this.refs.injectButton.focus()
which if equivalent functionally seems like a better solution. In the docs it even mentions that using findDOMNode()
will be unnecessary in most cases.
Was there a specific case you are guarding against to take the more conservative approach?
Thanks
Hi, I'm playing with this for this first time. My test file is being skipped, and nothing is being logged as to why.
jscodeshift -t react-codemod/transforms/create-element-to-jsx.js -p --dry --run-in-band -v 2 output.js
Processing 1 files...
Running in dry mode, no files will be written!

Is there any way I can get more output from it?
If I have separate file for proptypes, it still imports react
-import { PropTypes } from 'react'
+import 'react';
I've tried saving my files in various encodings both in Sublime Text and by converting using iconv
but I get encoding errors every time:
MacOS 10.11.3, node 5.7.0, npm 3.6.0

import {Component, PropTypes} from 'react';
converted to:
import { Component } from 'react';
and didn't create 'import PropTypes from 'prop-types';'
using the fixed: https://github.com/solidwareio/react-codemod/commit/7eb11895bcf5148754f159ddbd6364cf1d87e828
Update:
Also:
import {PropTypes} from 'react';
converted to:
import 'react';
We use
import React, { PropTypes, Component } from 'react';
export default class Foo extends Component {
and the PureComponent transform skips all of these. Even if this doesn't get fixed its worth noting here in case someone else is wondering why all their files are being skipped.
Thanks for updating the test suite. There is currently a build warning:
Running 1 test suite...class-test.js: `MyComponent4` was skipped because of invalid field(s) `foo` on the React component. Remove any right-hand-side expressions that are not simple, like: `componentWillUpdate: createWillUpdate()` or `render: foo ? renderA : renderB`.
