This directory contains simple examples of components in Component Framework (Components v2).
If these components are not present in your build, they can be added by appending --with //examples to your fx set command. For example:
$ fx set core.x64 --with //examples --with //examples:tests $ fx build
(Disclaimer: if these build rules become out-of-date, please check the Build documentation and update this README!)
These examples are all stored in a package named components-basic-example.
There isn't yet a convenient way to directly run a native v2 component, so these examples are run by launching a new component manager in a v1 component to run them. A component manager packaged to be a v1 component is also included in this package for this purpose.
The component manager can be invoked with the run command, and given a URL for which test component to launch. As an example, the following will run the hello_world example.
$ fx shell 'run fuchsia-pkg://fuchsia.com/components-basic-example#meta/component_manager_for_examples.cmx fuchsia-pkg://fuchsia.com/components-basic-example#meta/hello-world.cm'
When the above command is run, the following output can be seen in fx log:
[682199.986470][5056597][5056599][hello_world] INFO: Hippo: Hello World!
To run a different example, replace hello-world with the name of a different manifest in meta/.
Make sure you have fx serve running in another terminal so your component can be installed!
To run one of the test components defined here, use fx test with the package name:
$ fx test hello-world-tests
