@baseapp-frontend

This is the baseapp-frontend monorepo that contains our apps and packages.

So, everything inside packages is meant to be part of the @baseapp-frontend packages, for instance:

- /packages
     -/authentication
     -/tsconfig

In that case, both authentication and tsconfig are unique packages, but they all belong to the @baseapp-frontend organization.

If one of the apps wants to consume any package feature, we could simply add that package as a dependency like this:

  "dependencies": {
    "@baseapp-frontend/authentication": "*",
    ...
  },

And then just import the feature needed:

import { useUser } from '@baseapp-frontend/authentication'

export default function Docs() {
  const {user} = useUser()

  return (
    <div>
      <h1>Find User</h1>
      <p>{user.firstName}<p>
    </div>
  )
}

Apps and Packages

• authentication: includes authentication modules such as login, signup, reset password, multifactor authentication and more.
• config: includes reusable configurations for eslint, prettier and jest.
• components: includes BaseApp modules such as comments, notifications, messages and more.
• design-system-mui: defines our design system configuration (e.g. color pallete, typography, spacings, etc). It also shares reusable components that make up the design system as a whole.
• docs: an app to document some packages's features.
• graphql: includes GraphQL's configurations and utilities.
• provider: includes provider of different kinds that have "use client" directive on top.
• test: extends React Testing Library features and export some util functions, mocks and test configurations.
• tsconfig: reusable typescript configs.
• utils: includes constants, functions, hooks and types that are generic enough to be reused between apps and packages.

NVM

This step is optional but it is highly suggested you use NVM.

Installation instructions can be found here: https://github.com/nvm-sh/nvm#installing-and-updating

Once installed run:

nvm use

Setup

This repository uses pnpm for package management. Ensure you have it installed:

• Installing pnpm

To install all dependencies for apps and packages, run the following command at the root of the repository:

pnpm install

Build

To build all apps and packages, run the following command:

pnpm build

# build only the authentication package
pnpm build --filter=authentication

Develop

To develop all apps and packages, run the following command:

pnpm dev

PNPM Catalog Overview

This monorepo manages some dependencies using pnpm catalogs. As a rule of thumb, we often add dependencies to the catalogs that are reused across multiple packages, rather than arbitrarily adding dependencies to these lists. This approach ensures that shared dependencies are centrally managed and consistently applied across the codebase.

Cataloging reused dependencies also facilitates easier updates and reduces the chance of dependency mismatches between different parts of the monorepo.

Make sure to keep @baseapp-frontend's catalog always up to date.

Using Package Versions from GitHub

If you need to install a package version that hasn't been published yet, follow the steps below. We use GitHub as the source for unpublished versions.

Steps:

1. Remove Catalog Entries:

Before using a package from GitHub, remove its catalog entry. This is necessary because pnpm doesn't handle catalogs well when using non-published versions. To remove the catalogs for the desired package, run the following command:

# will replace catalogs for utils and authentication packages
node replace-catalogs.js utils authentication

# will replace catalogs for all packages
node replace-catalogs.js

2. Commit and Push:

After making the change, commit and push your code. This makes it easy to undo once the package has been published.

git commit -m "Temporarily remove catalogs to use GitHub version"

3. Copy the Commit Hash:

Push the code to GitHub and copy the last commit hash. You’ll need this hash to point your consumer app to the correct version of the package.

4. Update Consumer App:

In the consumer app (the app that will use the non-published version), update the package entry to point to the GitHub source. Replace <commit-hash> with the actual commit hash you copied:

"@baseapp-frontend/components": "git+https://github.com/silverlogic/baseapp-frontend.git#<commit-hash>&path:packages/components",

5. Undo Changes and Merge:

Once you’ve finished testing or using the non-published version, undo the commit that removed the catalogs. You can now proceed with merging and publishing the changes.

git revert <commit-hash>

Packages Versioning and Publishing

We have 3 mandatory steps before pushing modifications:

1. If we did any modification in any package, before pushing we need to generate a changeset, which basically is a file that summarizes which type of changes we did (major, minor or none) alongside with the summary of those changes. So, to do that we run:

pnpm changeset

After that, we need to choose which packages were changed, and the bump they had and write the summary for that change.

2. With the changesets created, we need to consume them to actually increase the package versions accordingly. So, we do:

pnpm version-packages

After running that, you might notice version bumps on the package's version and an update on the package's CHANGELOG.md.

3. By now, we just need to commit & push those files and, after merging the PR, the packages updates will be automatically published :)

Documentation Guide

To ensure that all pages, components, and utilities are thoroughly documented in Storybook, please follow these steps.

1. Write Storybook Stories

Each component and page should have a corresponding Storybook story that showcases its various states and usage scenarios:

• Include All Possible States: Each story should cover possible states of the component or page, such as default, disabled, loading, or error configurations.
• Use Mocks for Data: Use MSW (Mock Service Worker) to mock any necessary API requests, ensuring stories are self-contained and reproducible.
• Decorators: Pass any necessary decorators to simulate the environment (e.g., authentication with withTokenSetup).
• Type Safety: Ensure correct typings for all props and arguments.
• Conciseness: Be thorough but concise, focusing on the most relevant states and interactions.

After creating the story:

• Add the story name to storySort in the preview.ts file to ensure it appears in the correct order. If you’re unsure where to add this, please ask a COP member for assistance.

2. Add MDX Documentation

In addition to stories, create an MDX file to provide detailed documentation for each page or component:

• Create an MDX File: Place the .mdx file in the corresponding __storybook__ folder. The file name should match the component or page name (e.g., Button.mdx for the Button component).
• Use Consistent Titles: Match the title in the MDX file to the Storybook story for consistency:
  • Pages: @baseapp-frontend-template / Pages/[PageName]
  • Components: @baseapp-frontend-template / [ComponentSection]/[ComponentCategory]/[ComponentName]
