Gimbal ❤️ CIs like Circle CI, Travis CI, Jenkins, and GitHub Actions.
You can install Gimbal globally using npm or yarn:
# with npm npm install --global @modus/gimbal # or with yarn yarn global add @modus/gimbal gimbal --helpNow the gimbal is executable throughout your system for any projects you want to audit.
You can also install it to a specific project as a development dependency.
# with npm npm install --save-dev @modus/gimbal # or with yarn yarn add --dev @modus/gimbalYour project should have been built in order to execute gimbal.
You can execute it via a npm script: (package.json):
{ "scripts": { "audit": "gimbal audit" } }# with npm npm run audit # or with yarn yarn auditYou don't need to Configure Gimbal, but we understand that defaults are optimistic, at least for existing projects that want to introduce performance budgeting.
To ease you be ready to use, let's start with some sample .gimbalrc.yml config files:
- Minimal
- Minimal with all native audits
- Using other audit plugins and more sample configurations
Please, make sure your project was build before executing gimbal.
You may save them as your .gimbalrc.yml file and run gimbal.
audits: - size configs: buildDir: buildaudits: - size - lighthouse - heap-snapshot - unused-source configs: buildDir: buildBefore executing this config file you should install mentioned plugins. For instance:
# with npm npm install @modus/gimbal-plugin-axe @modus/gimbal-plugin-last-value @modus/gimbal-plugin-sqlite # or with yarn yarn add @modus/gimbal-plugin-axe @modus/gimbal-plugin-last-value @modus/gimbal-plugin-sqliteIn case you don't use build as your build directory and an exception raises with an error concerning a nonexistent build directory, please create one and run gimbal again.
