Building and Using

Dependencies

• Install make.
• Run make setup to install dev environment requirements.
  • This also installs some client side git hooks.

Build and Run

• Build: make server. Then run ./bin/<your architecture>/server [parameters]
• Run without building: go run web/cmd/server/main.go [parameters]

Example with a dummy configuration: go run web/cmd/server/main.go -config etc/configs/fake.json. Then visit http://localhost:8080 to access remote control.

Examples

• SimpleServer - example for creating a simple custom server.
• MySensor - example for creating a custom sensor.
• MyComponent - example for creating a custom resource subtype.

SDKs

Multiple SDKs are available for writing client applications that interface with the Viam RDK.

• Go: Provided by this repository here. Documentation can be found here
• Python: Docs, Repository
• Rust: Repository

API

The API is defined with Protocol Buffers/gRPC which can be found at https://github.com/viamrobotics/api.

Conventions

• Write tests!
• Follow this Go Style Guide.
• Run make lint and make test.
• Run make build and commit resulting frontend artifacts.
• Use imperative mood for commits (see Git Documentation).
• Prefer metric SI prefixes where possible (e.g. millis) https://www.nist.gov/pml/weights-and-measures/metric-si-prefixes. The type of measurement (e.g. meters) is not necessary if it is implied (e.g. rulerLengthMillis).

Committing

• Follow git's guidance on commit messages:

Describe your changes in imperative mood, e.g. "make xyzzy do frotz" instead of "[This patch] makes xyzzy do frotz" or "[I] changed xyzzy to do frotz", as if you are giving orders to the codebase to change its behavior. Try to make sure your explanation can be understood without external resources. Instead of giving a URL to a mailing list archive, summarize the relevant points of the discussion.

• Each commit has a linting pre-commit hook run if make setup was used. It can be skipped with git commit --no-verify.

Frontend

To start the client development environment, first run the same go run command mentioned in Building and Using, but with the environmental variable ENV=development (e.g. ENV=development go run web/cmd/server/main.go -debug -config etc/configs/fake.json).

Then navigate to web/frontend and run npm start in a new terminal tab. Visit localhost:8080 to view the app, not localhost:5173. The latter is a hot module replacement server that rebuilds frontend asset changes.

Frontend against a remote host

See documentation in Direct Remote Control.
