Applicable to: OpenHarmony SDK 3.2.5.3, stage model of API version 9

The third- and fourth-party libraries are not yet compatible with the stage model of API version 9 and cannot be used.

Can I transfer project-level dependencies?

Applicable to: OpenHarmony SDK 3.2.5.3, stage model of API version 9

For example, if project A depends on project B and project B depends on project C, can project A directly use the APIs provided by project C?

No. Project A cannot directly use the APIs provided by project C. The project packing tool NPM does not support dependency transfer. To use the APIs provided by project C, you can add the dependency of project C to project A.

How do I obtain available third-party libraries?
