Create an Optic Ruleset

Optic Rulesets are written in Typescript using Optic's SDK. If you have written Spectral rules, the first thing you will notice is that Optic does not rely on JSON Path. Instead, rules are attached to OpenAPI entities i.e. property, or operation. Specific patterns in the spec can be matched using a predicate matches: (...) => true | false, and rules can be triggered when parts of the spec are added, removed or changed. We will go into examples soon, but first let's set up a project:

Get Started

Use the ruleset init command to Bootstrap a Typescript project with the correct test, build and publish scripts already configured:

optic ruleset init

You will need to have the optic CLI installed to run this command. Install Instructions

Optic will write the following files:

├── README.md
├── jest.config.js
├── package.json
├── src
│   ├── __tests__
│   │   └── main.test.ts
│   └── main.ts
└── tsconfig.json

If you use yarn, run yarn install. If you use npm run npm install

Scripts

  • yarn run build bundles all the rules and dependencies into a single .js file for simple distribution.

  • yarn run test runs any tests you have written to ensure your rules work as expected

  • yarn run upload deploys your ruleset to Optic Cloud. In the dashboard you will have the option to run this ruleset whenever a tracked API changes.
