Contributing to Arkime

✨ Glad to see you here! ✨

Just have a question ❓

Where do I start? 🚥

First, checkout the main Arkime README for information on how to build and run Arkime. We do all development on MacBook Pros.

Then, get some test data!

  • If using a VM/docker make sure your dev host has at least 2-3G of memory
  • Make sure node is in your path, currently main only supports Node version 16 (Use the latest version in "Node Versions" section of CHANGELOG), we recommend using nvm to manage what version of node is installed
  • Install OpenSearch OR Elasticsearch (Use the latest version in "OpenSearch Versions" or "Elasticsearch versions" section of CHANGELOG)
  • Start OpenSearch/Elasticsearch
  • If on a Mac install either Homebrew or MacPorts
  • Run ./easybutton-build.sh
  • Run make check from the top level directory, this will
    • run npm ci everywhere (to install all the necessary dependencies)
    • run tests.pl and tests.pl --viewer in the tests directory (to load PCAPs)

Note: this will only work if viewer is not already running.

You should now have test data loaded, so let's start the web app:

  • Move to the Arkime viewer directory
  • Run npm ci
  • Move back up to the top level Arkime directory
  • Run npm run viewer:test
  • Now browse to the app at http://localhost:8123

If you want to run Arkime in non-anonymous mode:

  • Move to the top level Arkime directory
  • run npm run viewer:dev this will automatically add an admin user (username: admin, password: admin)

🕐 On first load, you will likely see this message: "No results or none that match your search within your time range." This is because the data that was loaded is from all time ranges, so make sure you search for ALL times ranges.

For more information about running the Arkime Viewer web application, visit the viewer README.

To contribute to Parliament or WISE, read their READMEs for information on how to build them for development

API Documentation

The API is documented using jsdoc and jsdoc2md.

If you update or create an API, please document it thoroughly with these items:

  1. METHOD - endpoint (e.g. GET - /api/sessions)
  2. Description
  3. Name the endpoint with @name endpointname (e.g. sessions). This is the name that will be reflected in the title of the endpoint and the table of contents.
  4. List the parameters including any defaults with @param (e.g. @param {number} date=1 - The number of hours of data to return (-1 means all data). Defaults to 1)
  5. Describe the return value(s) with @returns (e.g. @returns {array} data - The list of sessions with the requested fields)

The documentation lives on our website at arkime.com/api. It is generated using the code documentation. Follow these steps to update the API documentation:

  1. Check out the arkimeweb repository in the same parent directory as the Arkime repository.
  2. Run npm run viewer:doc from the arkime directory. If you checked out the arkimeweb repository into a different location, you can run npm run viewer:doc-location -- <path/to/arkimeweb/_wiki/api_docs.md>.
  3. Run the arkime website locally (find out how here) to make sure all of your documentation is correct.
  4. Make a PR to arkime and arkimeweb with your changes.

Upgrading Cyberchef

  1. Find the latest version of Cyberchef from GitHub.
  2. Inside the release directory run ./new_cyber_chef.pl <versionnumber>
  3. Test new CyberChef works
  4. Commit changes
