Platform development
Introduction
This summary should give you a detailed setup description for initiating the OpenCTI setup environment necessary for developing on the OpenCTI platform, a client library or the connectors. This page document how to set up an "All-in-One" development environment for OpenCTI. The devenv will contain data of 3 different repositories:
- Platform: https://github.com/OpenCTI-Platform/opencti
- Connectors: https://github.com/OpenCTI-Platform/connectors
- Client python: https://github.com/OpenCTI-Platform/client-python
Platform
Contains the platform OpenCTI project code base:
- docker-compose (docker or podman)
~/opencti/opencti-platform/opencti-dev - Web frontend (nodejs / react)
~/opencti/opencti-platform/opencti-graphql - Backend (nodejs)
~/opencti/opencti-platform/opencti-frontend - Worker (nodejs / python)
~/opencti/opencti-worker
Connectors
Contains a lot of developed connectors, as a source of inspiration for your new connector.
Client python
Contains the source code of the python library used in worker or connectors.
Prerequisites
Some tools are needed before starting to develop. Please check Ubuntu prerequisites or Windows prerequisites
Clone the projects
Fork and clone the git repositories
- https://github.com/OpenCTI-Platform/opencti/ - frontend / backend
- https://github.com/OpenCTI-Platform/connectors - connectors
- https://github.com/OpenCTI-Platform/docker - docker stack
- https://github.com/OpenCTI-Platform/client-python/ - python client
Dependencies containers
In development dependencies are deployed trough containers.
A development compose file is available in ~/opencti/opencti-platform/opencti-dev
You have now all the dependencies of OpenCTI running and waiting for product to run.
Backend / API
Python virtual env
The GraphQL API is developed in JS and with some python code. As it's an "all-in-one" installation, the python environment will be installed in a virtual environment.
cd ~/opencti/opencti-platform/opencti-graphql
python3 -m venv .venv --prompt "graphql"
source .venv/bin/activate
pip install --upgrade pip wheel setuptools
yarn install
yarn install:python
deactivate
Development configuration
The API can be specifically configured with files depending on the starting profile. By default, the default.json file is used and will be correctly configured for local usage except for admin password
So you need to create a development profile file. You can duplicate the default file and adapt if for you need.
At minimum adapt the admin part for the password and token.
"admin": {
"email": "admin@opencti.io",
"password": "MyNewPassord",
"token": "UUID generated with https://www.uuidgenerator.net"
}
Install / start
Before starting the backend you need to install the nodejs modules
Then you can simply start the backend API with the yarn start command
The platform will start logging some interesting information

If you want to start on another profile you can use the -e parameter. For example here to use the profile.json configuration file.
Code check
Before pushing your code you need to validate the syntax and ensure the testing will be validated.
For validation
yarn lint
yarn check-ts
For testing
For starting the test you will need to create a test.json file. You can use the same dependencies by only adapting all prefix for all dependencies.
yarn test:dev
Frontend
Install / start
Before starting the backend you need to install the nodejs modules
Then you can simply start the frontend with the yarn start command
The frontend will start with some interesting information
[INFO] [default] compiling...
[INFO] [default] compiled documents: 1592 reader, 1072 normalization, 1596 operation text

Code check
Before pushing your code you need to validate the syntax and ensure the testing will be validated.
For validation
yarn lint
yarn check-ts
For testing
yarn test
Worker
Running a worker is required when you want to develop on the ingestion or import/export connectors.
Python virtual env
cd ~/opencti/opencti-worker/src
python3 -m venv .venv --prompt "worker"
source .venv/bin/activate
pip3 install --upgrade pip wheel setuptools
pip3 install -r requirements.txt
deactivate
Install / start
Connectors
For connectors development, please take a look to Connectors development dedicated page.
Production build
Based on development source you can build the package for production. This package will be minified and optimized with esbuild.
After the build you can start the production build with yarn serv. This build will use the production.json configuration file
