Instructions

The study is built with reVISit, a framework for creating and deploying interactive visualization studies via declarative configuration.

Build Instructions

To run this demo experiment locally, you will need to install node on your computer.

• Clone https://github.com/revisit-studies/study
• Run yarn install. If you don't have yarn installed, run npm i -g yarn.
• To run locally, run yarn serve.
• Go to http://localhost:8080 to view it in your browser. The page will reload when you make changes.

Release Instructions

Releasing reVISit.dev happens automatically when a PR is merged into the main branch. The name of the pull request should be the title of the release, e.g. v1.0.0. Releasing creates a tag with the same name as the PR, but the official GitGub release should be created manually. The main branch is protected and requires two reviews before merging.

The workflow for release looks as follows: Develop features on feature branch | PRs Dev branch | PR (1 per release) Main branch | Run release workflow on merge References are updated and commit is tagged
