Webviz

Drag and drop your own bag files into Webviz to explore your robotics data, or connect to a live robot or simulation using the rosbridge_server.

Webviz is a web-based application for playback and visualization of ROS bag files. This repository also contains some libraries that can be used independently to build web-based visualization tools.

• webviz-core (homepage, tool, github): A tool to inspect ROS bags.
• regl-worldview (homepage, npm, github): React library for rendering 2D and 3D scenes using regl.
• @cruise-automation/hooks (npm, github): A list of resusable React hooks.
• @cruise-automation/button (npm, github): React button component that supports animated progress for destructive actions, "pulse" animation, and Bulma classes.
• @cruise-automation/tooltip (npm, github): React component that uses popper.js to add rich, customizable tooltips to DOM elements.

Please see the individual package READMEs for details on how to install and use them.

How to use Webviz

We have in-app help resources. Go to the application and click the "?" icon in the top right. Each individual panel also has a "?" icon in its top right.

Running the static Webviz application

We recommend using the hosted version of Webviz, which can connect to your rosbridge_server or stream in bag data from your S3/GCS bucket. This way you'll always use the latest version of Webviz.

However, sometimes the hosted version is inconvenient, when streaming data from robots on the field where there is poor internet connectivity. For this it is useful to use a static build of webviz.

Docker

The easiest way to use the static build, is to use our Docker image, which is automatically built on every commit to the master branch.

docker run -p 8080:8080 cruise/webviz

Building manually

npm run bootstrap # install dependencies
npm run build # build all packages
npm run build-static-webviz # generate static build in __static_webviz__
npm run serve-static-webviz # serve static build on localhost:8080

Developing

• npm run bootstrap in the root directory to install dependencies.
• npm run build to run a single build or npm run watch to watch and build.
• npm run docs to run the docs app (e.g. go to http://localhost:8080/app to open Webviz). Requires build to be run first.
• npm run storybook to run storybook. Requires build to be run first.
• npm run screenshot-local or npm run screenshot-local-debug to generate screenshots from stories.
• npm run lint to run the linters (and npm run lint:fix to automatically fix issues).
• npm run flow to run Flow.
• npm run flow-typed-rebuild to update the flow-typed definitions (any time when changing packages).
• npm test to run tests.
• npm run build-static-webviz to make a special build of just the Webviz application in the __static_webviz__ directory.
• npm run serve-static-webviz to host the contents of the __static_webviz__ directory on localhost:8080.

If you have the right permissions, you can publish:

• npm run publish to publish npm packages.
• npm run docs-deploy to deploy that statically hosted website (this is also done automatically in CI on the master branch).

If you run into any issues, file an issue on Github or ask us on Slack (see above).

Contributing

PRs, bug reports, and feature requests are welcome! Please observe CONTRIBUTING.md and CODE_OF_CONDUCT.md when making a contribution.

Note that while it's possible to fork Webviz to make your own custom version, we'd encourage you to use webviz.io/app and propose generic solutions that everyone would benefit from. Cruise also still has its own fork of Webviz, but long term we'd like to move away from that. For examples of generic features, see the Node Playground panel, using generic RViz markers in the 3d panel, streaming in bags from any cloud service, loading layouts hosted on arbitrary URLs, and so on. We'd love your creative ideas for making Webviz widely useful!
