Twake Calendar Frontend

Goals

This project aims at service a Single Page Application allowing a user to interact with its calendar.

This frontend-only application will interact with:

• esn-sabre CalDAV + CardDAV server, tailor made for LINAGORA needs.
• Twake Calendar side service that delivers additional backend features for Sabre.

It is meant as a drop in replacement of esn-frontend-calendar.

Contributing

Formating

We use Prettier to keep code style consistent.
A .prettierrc file is already included in the repo, so formatting rules are predefined.

Before committing, make sure you format your files either using your IDE Prettier extension or Prettier CLI.

Running it

Requirement: node 24+

Compile it and run it

In the project directory, you can run:

npm start

Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits.
You will also see any lint errors in the console.

npm test

Launches the test runner in the interactive watch mode.
See the section about running tests for more information.

npm run build

Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.
Your app is ready to be deployed!

See the section about deployment for more information.

npm run eject

Note: this is a one-way operation. Once you eject, you can’t go back!

If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.

Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.

You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.

Run it with docker

After compiling the project with npm (see previous section) simply run:

docker build -t linagora/twake-calendar-front .

Then edit .env.js in order to match your configuration then run it with:

docker run -d \
  -v $PWD/.env.example.js:/usr/share/nginx/html/.env.js \
  -p 5000:80 \
  tcal-front

And then visit https://localhost:5000.

Configuring it

App grid

An applist is configurable in the public folder to setup the grid of app accessible within Twake Calendar.

1. Copy public/appList.example.js to public/appList.js
2. Place your app icons in public/assets/images/svg/ directory
3. Configure each app with three fields:

• name: the app's name
• icon: the path to the app's icon (relative to public folder, e.g., /assets/images/svg/app-chat.svg)
• link: the app's link or URL

Example:

var appList = [
  {
    name: "Chat",
    link: "/twake",
    icon: "/assets/images/svg/app-chat.svg",
  },
  {
    name: "Drive",
    link: "/drive",
    icon: "/assets/images/svg/app-drive.svg",
  },
  {
    name: "Mail",
    link: "/mail",
    icon: "/assets/images/svg/app-mail.svg",
  },
];

Note: appList.js is gitignored, so each environment can have its own configuration. The icon files in public/assets/images/svg/ should be committed to the repository.

Roadmap

The Minimum Viable Product involves all features currently used in production for esn-frontend-calendar.

It includes basic calendaring features and shared / delegated calendar capacity.

After completing the MVP which should be done ~Q1 2026 we will work on additional integrations (viso, drive), resources, tasks, and much more exciting features.
