Contributing
Add new translate service
- Copy
src/modules/services/_template.ts > src/services/<your-service-id>.ts;
- Fill in the required fields (id, type, and translate) and optional fields (name, helpUrl, defaultSecret, secretValidator(secret), and config(settings)) following the introduction. The translation function sets the translation result to
data.result if runs successfully and throws an error if fails;
- Import the new service object in
src/modules/services/index.ts.
- Add locale string
service.${serviceId} and service-<your-service-id>-dialog-xxx(if necessary) in addon/locale/${lang}/addon.ftl.
- Build and test.
