About the project

This is a service to validate documents against the CSAF standard. It uses the csaf-validator-lib under the hood which is included as a git subtree module.

Getting started

To run the validator service you basically need the same as for developing.

• install Node.js 16
• install production dependencies and copy all relevant files to the dist folder by running npm run dist
• copy the content of the dist folder to your working directory
• Make sure to set the environment variable NODE_ENV to production
• Configure the service using a local-production.json file in backend/config. All available parameters are outlined in backend/config/development.json. See https://www.npmjs.com/package/config for more information on how to configure using different techniques such as environment variables.
• test 6.3.8 requires an installation of hunspell.
  • For more details on how to manage languages, please also see Managing Hunspell languages
• start the service with node backend/server.js

To manage the process you can use Docker or an init system of your choice.

You most likely also want to run this behind a reverse proxy to handle TLS termination or CORS headers if the service is accessed from other domains. See https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS for more information.

Documentation

The documentation is available as a swagger resource provided by the service itself under /docs. So once the server is running, visit http://localhost:<config port>/docs in your browser. The default port of the application 8082. See configuration to learn about ways to change it.

Generate documentation

The server needs to be running and the openapi-generator-cli must be installed. The file backend/lib/app.js needs to reflect the target version. Then, you can use the following commands to generate the documentation:

openapi-generator-cli generate -i http://localhost:8082/docs/json -g html -o ./documents/generated/html/
openapi-generator-cli generate -i http://localhost:8082/docs/json -g asciidoc -o ./documents/generated/asciidoc/

Testing

Many tests are integration tests which need a running server. So make sure to start it before running the tests:

npm run dev

Tests are implemented using mocha. They can be run using the following command:

npm test
