Developing for CCSync

This section gives a brief information about almost everything that you would need to setup CCSync for development, or deployment.

If you still have any queries, contact us on Github

Environment Architecture

The diagram below is a representation of how various components are connected to enable sync on the CCSync website, and the Taskwarrior Flutter App

Setting up CCSync for personal use

Prerequisites

Docker
Google OAuth Keys

Steps to run CCSync for personal use

Clone the CCSync repository and switch to docker-prod branch.
Navigate to production directory by cd production

Create a file named .backend.env with the following attributes:

CLIENT_ID="client_ID" # Google Auth Secret from Prerequisites
CLIENT_SEC="client_SECRET" # Google Auth Secret from Prerequisites
REDIRECT_URL_DEV="http://localhost:8000/auth/callback" 
SESSION_KEY="generate a secret key using 'openssl rand -hex 32'"
FRONTEND_ORIGIN_DEV="http://localhost" # the url of the web frontend, so as to avoid CORS errors
CONTAINER_ORIGIN="http://YOUR_CONTAINER_NAME:8080/" # deployed taskchampion-sync-server container, should be production-syncserver-1 by default

Run docker-compose pull to pull the CCSync images.
Run docker-compose up to finally start the project.
The frontend should now be available on localhost:80, backend on localhost:8000, and syncserver on localhost:8080

Setting up a Development Environment

Prerequisites

Docker
Google OAuth Keys

Steps to setup the frontend

Navigate to the frontend directory and run the command:
```
npm install
```
Create a .env file in the same directory.

If you want to use docker, set the environment variables in .env as:

VITE_BACKEND_URL="http://localhost:8000/" # this is the backend to which the app or the web frontend interacts with
VITE_FRONTEND_URL="http://localhost:80" # the url of our web frontend, so as to avoid CORS based errors
VITE_CONTAINER_ORIGIN="http://localhost:8080/" # url of the deployed taskchampion-sync-server container

Else, set the environment variables in .env as:

VITE_BACKEND_URL="http://localhost:8000/" # this is the backend to which the app or the web frontend interacts with
VITE_FRONTEND_URL="http://localhost:5173" # the url of our web frontend, so as to avoid CORS based errors
VITE_CONTAINER_ORIGIN="http://localhost:8080/" # url of the deployed taskchampion-sync-server container

Run the frontend container only:

docker-compose build frontend
docker-compose up

Steps to setup the backend

Navigate to the backend directory and run the commands:
```
go mod download
go mod tidy
```
Create a .env file in the same directory.
Go to Google cloud credential page for generating client id and secret.

If you want to use docker, set the environment variables in .env as:

CLIENT_ID="client_ID" # Google Auth Secret
CLIENT_SEC="client_SECRET" # Google Auth Secret
REDIRECT_URL_DEV="http://localhost:8000/auth/callback" 
SESSION_KEY="generate a secret key using 'openssl rand -hex 32'"
FRONTEND_ORIGIN_DEV="http://localhost" # the url of the web frontend, so as to avoid CORS errors
CONTAINER_ORIGIN="http://YOUR_CONTAINER_NAME:8080/" # url of the deployed taskchampion-sync-server container

Else, set the environment variables in .env as:

CLIENT_ID="client_ID" # Google Auth Secret
CLIENT_SEC="client_SECRET" # Google Auth Secret
REDIRECT_URL_DEV="http://localhost:8000/auth/callback"
SESSION_KEY="generate a secret key using 'openssl rand -hex 32'"
FRONTEND_ORIGIN_DEV="http://localhost:5173" # the url of the web frontend, so as to avoid CORS errors
CONTAINER_ORIGIN="http://localhost:8080/" # url of the deployed taskchampion-sync-server container

Run the backend container only:

docker-compose build backend
docker-compose up

Note: If you plan to run the backend without Docker, run it as a root user preferably on WSL or any Linux Distro with a user that has elevated permissions to modify files and directories.

Note: The Taskchampion sync server is currently being pulled from the repository here.

Steps to setup the Taskwarrior Flutter app with CCSync

For development/personal purposes, in order to use CCSync with Taskwarrior Flutter app, one needs to setup only the backend and the sync server. The frontend setup is optional.
Open the api_service.dart file.
For baseUrl, replace http://YOUR_IP:8000 with the deployed API endpoint. YOUR_IP refers to the IP address of the terminal or Docker container that is hosting the backend currently.
For origin, replace http://localhost:8080 with the deployed sync server endpoint.
Set sync.server.origin in your Taskwarrior configuration to the deployed sync server URL.

Here's how your api_service.dart should look after these changes:

class ApiService {
// Use deployed values for baseUrl and origin
        String baseUrl = 'http://deployed-api-endpoint.com'; // replace with actual deployed API endpoint
        String origin = 'http://deployed-sync-server-endpoint.com'; // replace with actual deployed sync server endpoint, although, for now, it is just a placeholder until next release or update
// Other ApiService code...
}

Run the app.

Troubleshooting

The sync might break most of the times due to wrong .env variables. Please ensure that your docker containers are visible and accessible, using ping <container_address> commands.

Testing

For testing backend, first navigate to the backend directory, and then run the tests
```
cd backend
go test <package_name>
```

Here, package_name is the test suite you want to run.

Similarly, for testing frontend, first navigate to the frontend directory, and then run the tests
```
cd frontend
npm test
```
Note: In order to setup / run tests for pages that have any URLs, for example, the HomePage.tsx, toggle the isTesting to true in frontend/src/components/utils/URLs.ts

Google OAuth Keys

Before starting the frontend, Go to Google cloud credential page for generating client id and secret. Read this guide for more information on these credentials and how these work. Follow these steps:

Go to Google's developer console.
Create a new project.
From within your project, create a new "Client ID" by going to "APIs & Auth" > "Credentials" and clicking on the "Create New Client ID" button.
Select "Web Application"
Enter the following for 'Authorized Javascript Origins':
```
http://127.0.0.1
http://localhost
```
Enter the following for 'Authorized Redirect URI':
```
http://127.0.0.1:8000/callback/
```
Save
You will be presented with your newly generated credentials that are required for setting up the backend.
