In case of json its doing both highlighting and error display. In case of yaml, only syntax highlighting is working. Other modes work fine and shows the error messages as mentioned above.

Even the annotations array is empty when checked. Additionally imported brace at the top too. Still it didnt help. Anyway found this and it mentions the syntax validation is available only for few lang.

Had to use other library which can parse yaml like yaml-js to get the errors and manually set the annotations. Even after setting the annotations props it doesnt work properly so had to get the editor reference and set it manually using editor.

This doesn't work properly though. I think that the editor is being re-initialized at each step which isn't much good :.

One solution would be to add a shouldComponentUpdate that only updates when properties have changed OR when the text property is not equal to the text displayed in the editor. I was having issues trying to capture the input using a setState.

It appears that having a defaultValue was causing some sort of conflict. I used value instead and now onChange and the editor works as at least how I expected. Not sure if this is what mjmdavis and dyf were experiencing. This will update the state of aceEditorValue with whatever is entered into the editor without re-rendering the entire component.

Works for my use case. So the issue here is we're tapping into ace editor's actual change event rather than listening and rerendering. It sounds like you want to be able to tap into the period of time when a change is happening. We could have another hook in componentWillReceiveProps that prevents an update.

Personally, i think brendanmcgivern 's solution is the cleanest though. Well, this is a huge bug and it is still there. The key issue, as I understand, is that you better not set state or do anything with the value right from the ace's onChange inline.

You better do it in the different component's function. Skip to content.

This requires the worker scripts to be located on your server and forces you to host the ace editor on your server as well. While that is ok in most cases, it prevents you from providing a fully working ace editor package.

That's where Brace comes in the game, it is a browserify compatible version of the ace editor. To get started with the implementation of Ace Editor in your React application, install the react-ace module.

To install, open a terminal, switch to the directory of your project and run the following command:. After the installation of the module you will be able to import the component to render in your view. For more information about this module, please visit the official repository at Github here. This component expects almost all the properties of the original AceEditor but instead of passing them as an object, they're providen with props:.
