Development

!JS Client Tests

Always make sure to adapt changes in the *.js files to the openeo.d.ts file.
If changes are larger you may want to run npm run tsd and regenerate the declaration file and cherry-pick your changes from there.

Generate a build: npm run build (generates openeo.js and openeo.min.js)

Generate the documentation to the docs/ folder: npm run docs

Check against the coding guidelines: npm run lint

Run tests:

* npm test (all tests)
* npm test browser (browser tests)
* npm test node (node tests)
* npm test builder (tests only the process builder)
* npm test earthengine` (full test suite using the Google Earth Engine back-end as server)
