Getting started

Usage

doccano has two options to run:

(Recommended) Docker Compose
Docker

The usage of docker compose version is explained in the README.md. We highly recommend that you should use docker compose version. However, we explain the usage of Docker version and Python/Node version for the additional information.

Docker

As a one-time setup, create a Docker container for Doccano:

docker pull doccano/doccano
docker container create --name doccano \
  -e "ADMIN_USERNAME=admin" \
  -e "ADMIN_EMAIL=admin@example.com" \
  -e "ADMIN_PASSWORD=password" \
  -p 8000:8000 doccano/doccano

Next, start Doccano by running the container:

docker container start doccano

To stop the container, run docker container stop doccano -t 5. All data created in the container will persist across restarts.

Go to http://127.0.0.1:8000/.

Setup development environment

You can setup development environment via Python and Node.js. You need to install Git and to clone the repository:

git clone https://github.com/doccano/doccano.git
cd doccano

Backend

The doccano backend is built in Python 3.8+ and uses Poetry as a dependency manager. If you haven't installed them yet, please see Python and Poetry documentation.

First, to install the defined dependencies for our project, just run the install command. After that, activate the virtual environment by runnning shell command:

cd backend
poetry install
poetry shell

Second, setup database and run the development server. Doccano uses Django and Django Rest Framework as a backend. We can setup them by using Django command:

python manage.py migrate
python manage.py create_roles
python manage.py create_admin --noinput --username "admin" --email "admin@example.com" --password "password"
python manage.py runserver

In another terminal, you need to run Celery to use import/export dataset feature:

cd doccano/backend
celery --app=config worker --loglevel=INFO --concurrency=1

After you change the code, don't forget to run mypy, flake8, black, and isort. These ensures the code consistency. To run them, just run the following commands:

poetry run task mypy
poetry run task flake8
poetry run task black
poetry run task isort

Similarly, you can run the test by executing the following command:

poetry run task test

Did you pass the test? Great!

Frontend

The doccano frontend is built in Node.js and uses Yarn as a package manager. If you haven't installed them yet, please see Node.js and Yarn documentation.

First, to install the defined dependencies for our project, just run the install command.

cd frontend
yarn install

Then run the dev command to serve with hot reload at localhost:3000:

yarn dev
