Validators for loopback projects not using a persistent datasource e.g. a REST datasource (without access to built-in validation methods). Validation done against model schemas contained in model.json files.
Trivial example validating form data.
function submitForm(data) {
var model = 'submit-form';
var isValid = validator.validate(data, model);
if (!isValid.valid) {
throw new Error(isValid.message);
}
else {
// save the form data
}
}
Tests are written using mocha and assertions done using shouldjs. To run the tests for this example simply clone this repository. Then, from the root of the project, run npm install to install dependencies.
When the dependencies are installed, run npm test from the root of the repository.
