Types - app vs lib

The application platform works to compile, test, and bundle both applications and front-end libraries in a consistent way. This ensures that all DHIS2 application components are cross-compatible and build processes can be configured from a central location.

The default app type (app) is intended to be connected and used within a DHIS2 instance. App platform also supports a type login_app which does not require a user to be authenticated (intended for a login app).

Building a Library is nearly identical to building an Application - just set the type: 'lib' property in d2.config.js. You can then optionally specify an entrypoint source file in entryPoints.lib - the default is src/index.js.
