Giant makes it easier for journalists to search, analyse, categorise and share unstructured data. It takes many file formats, indexes them (including converting images to text using OCR) and provides a UI for search. Users can upload their own files but it also scales up to terabytes of data.
Giant is part of the Guardian's "Platform for Investigations" suite, you will see references
to pfi
in the code. Under development since 2017, it's written in Scala and Typescript and
is maintained by the Investigations & Reporting team.
If Giant doesn't fit your needs, check out Aleph from the OCCRP and Datashare from the ICIJ.
Giant has the following pre-requisites for local development:
Giant uses three databases, run locally in Docker through docker-compose.yaml:
There are two optional dependencies:
brew install tesseract
brew install wkhtmltopdf
Elasticsearch requires Docker to have at least 4GB of memory from the preferences menu otherwise it will exit with no log output and error 137.
For Guardian developers:
Select the correct version of node:
nvm use
Then run the setup script:
./scripts/setup.sh
Seed the configuration:
./scripts/cluster-setup.sh
Run the Scala backend:
./scripts/start-backend.sh
This will also automatically launch the databases in the background by running
docker-compose up -d
.
In a separate terminal, run the Create React App frontend:
./scripts/start-frontend.sh
The frontend script will wait for the backend to start before launching Giant at
http://localhost:3000
.
Once Giant has started, follow the admin quickstart guide.
You can use dev-nginx to more easily access Giant and the backing databases whilst running locally.
dev-nginx setup-app util/nginx-mapping.yml

To run all unit tests:
sbt test
To run all integration tests:
sbt int:test
To run a specific integration test:
sbt 'int:testOnly controllers.api.WorkspacesITest'
To terminate the databases without losing data:
docker-compose down
To terminate and delete data:
docker-compose down -v
The Guardian welcomes contributions to Giant. We do not yet have a publicly accessible CI server but please ensure all tests pass by running the build script locally:
./scripts/teamcity.sh
We do not yet publish deployment templates for Giant in either cloud hosts or locally. If you are interested in deploying Giant please get in touch by raising a GitHub issue on this repository.
