@corva/ui

develop: main:

This repo contains components/utils which are shared for Corva ui apps.

When you need some library changes

Currently @corva/ui library is owned by the Dev Center team, but is developed by every Corva FE developer. So, if you need to make some update in it - you can do it by yourself. For small updates - just make a PR - and someone from the Dev Center team will review it.

If it's something pretty big - it's better to reach out someone from the Dev Center team first, to tell what you need and get feedback how to better do it. Otherwise - you risk that your huge PR on which you worked a week can be rejected because it can be not consistent with the rest of the lib

Release & deploy of the library

How to bump the version? What should be the branch name? And other more advanced cases, like release/hotfixes. The guideline for all of these cases can be found here (Corva access required)

Stories for every public component

Every public @corva/ui component has a corresponding .stories.js file that describes the component. When you work with public @corva/ui components - please also update it's stories.js file when it's necessary

Build-time variables

Local development

• yarn storybook will launch local storybook server which is convenient to use for components testing when you work on public components. That's a playground for building public components.
• yarn start will open ExampleApp.js in your browser. That's a playground for building non-public components (such components will be moved from @corva/ui soon)

Link local @corva/ui to your app

Pre-requisite

• Make sure you are using @corva/ui with latest updates from development branch

• If your app is using getWebpackConfig from @corva/ui instead of @corva/dc-platform-shared, migrate it according to this guide

Steps to link your local DC app**

1. Run yarn build-dev or yarn build-watch in @corva/ui repo
   Note: yarn build will not work for linking

2. cd ./dist and run yarn link in @corva/ui dist folder (only first time)

3. Run yarn link @corva/ui in your local DC app root folder

4. Add following parameters to the config-overrides.js.
   It should avoid the issue of mulitple React instances and the MUI styling issue

{
    resolve: {
        alias: {
            react: path.resolve('./node_modules/react'),
            '@material-ui': resolve('./node_modules/@material-ui'),
        }
    }
}

5. Run yarn start in your local DC app root folder

Note: npm link will not install @corva/ui dependencies in your node modules folder. If you want to debug a change in @corva/ui dependencies, you should use yarn add file:../corva-ui/dist, this will install new dependencies.

Troubleshooting

Failed to compile.
Module not found: Can't resolve '@corva/ui' in ...

Most likely you need to migrate to @corva/dc-platform-shared for cjs webpack config usage

Error.
Invalid hook call. Hooks can only be called inside of the body of a function component...

In that case, your bundler might “see” two Reacts — one in application folder and one in your library folder. Assuming myapp and mylib are sibling folders, one possible fix is to run npm link ../myapp/node_modules/react from mylib. This should make the library use the application’s React copy.

Or change the webpack configuration in config-overrides.js file in your app. (Don't commit the changes of this file)

{
    resolve: {
        alias: {
            react: path.resolve('./node_modules/react')
        }
    }
}

Material UI styles are corrupted

Add the following parameter to the config-overrides.js file in your app

{
    resolve: {
        alias: {
            '@material-ui': resolve('./node_modules/@material-ui')
        }
    }
}
