Hi all,
I'm pleased to announce that v1.2.0 of [node-red-contrib-uibuilder](https://github.com/TotallyInformation/node-red-contrib-uibuilder) has been released. Please update as soon as possible as this fixes a hidden bug.
If you want to see what is coming next, please see [Issue #46](https://github.com/TotallyInformation/node-red-contrib-uibuilder/issues/46) on GitHub.
In case you don't know, uibuilder is designed to be an easy way to develop custom user interfaces integrated to Node-RED. Is a Node-RED Dashboard UI too restrictive or too slow, or maybe you just want to use a different front-end framework? uibuilder is there to help. What's the catch? Well, uibuilder doesn't hold your hand, you will need to know at least a little html and JavaScript. Check out the [uibuilder WIKI](https://github.com/TotallyInformation/node-red-contrib-uibuilder/wiki) though for some examples that will help you get going.
## Changelog
- **CHANGED** `url` property is now validated. It is required, it cannot be more than 20 characters long. It cannot be 'templates' (in preparation for a v2 improved template handling feature).
- **CHANGED** The admin API's `/uibfiles`, `/uibgetfile`, `/uibputfile` and `/uibindex` now have parameter validation.
- **CHANGED** Code for file/folder locations, e.g. `/uibuilder` improved. Made to use a single variable. In preparation for better support of projects (probably in v2 as that may be a breaking change).
- **CHANGED** Code comments improved, more use of JSDoc.
- **CHANGED** Default file name to be edited is changed to `index.html` rather than `index.js` as it is more likely to exist.
- **CHANGED** Improved the `uibindex` admin API, added additional details. Use the type parameter set to 'json' or 'urls' (lists the urls in use by all of the instances of uibuilder, used by the admin interface to ensure unique urls). The default is to return a web page containing details. Admin ui help text also updated to include the admin API's.
- **CHANGED** Master template folder - files moved to sub-folder to allow for multiple master templates (e.g. VueJS as well as jQuery). In readiness for future changes.
- **CHANGED** General utility functions moved to a separate library, `tilib`.
- **CHANGED** New `tilib` function added `getNpmRunScripts`. Given a path, returns a list of available scripts from the package.json file in that path - or `undefined` if the file doesn't exist. If the optional 2nd parameter is supplied, looks for a matching script name and returns the script text - or `null` if the script isn't there. In preparation for adding npm processing (install, build, etc.).
- **CHANGED** Paramterised Master Template Folder. Preparation for more flexible template processing.
- **FIXED** ExpressJS app.use paths were not being removed on close processing.
**Current Version Limitations**
- There are currently no checks to prevent you losing changes to edits if you close the admin window without saving the file.
- If you create sub-folders in your `src` folder, you will not be able to edit the files there. Keep everything in the `src` folder for now. Let me know if this is limiting for you.
