Hacking on the Panodata Map Panel

Introduction

The easiest way to get started is to git clone the project repository directly into the data/plugins of your Grafana instance followed by building it there.

Grafana will read in the dist folder first. So, to see your changes in Grafana, you will have to build the plugin once. However, you do not need to restart your local Grafana server after every change, just refreshing the page will be sufficient.

Sandbox setup

The easiest way to invoke a development sandbox is by using Docker.

# Run with Grafana 7
docker run --publish=3000:3000 --volume=$PWD/dist:/var/lib/grafana/plugins/panodata-map-panel grafana/grafana:7.5.10

# Run with Grafana 8
docker run --publish=3000:3000 --volume=$PWD/dist:/var/lib/grafana/plugins/panodata-map-panel --env=GF_PLUGINS_ALLOW_LOADING_UNSIGNED_PLUGINS=panodata-map-panel grafana/grafana:8.0.6

Because the version of node-sass used as transitive dependency is apparently not compatible with Node 16 yet, let's use Node 15:

brew install nodeenv
nodeenv --node=15.14.0 .nenv
source .nenv/bin/activate

Release

  1. Install packages: npx yarn install
  2. Bump version within package.json and update CHANGELOG.md
  3. Commit changes
  4. Tag repository: git tag 0.xx.0
  5. Push repository: git push && git push --tags
  6. Build and package: make package When this process succeeds, packages can be found within the ci/packages/ folder. The Error signing manifest warning can optionally be ignored, YMMV.
  7. Upload to GitHub release assets:
    • brew install github-release
    • export GITHUB_TOKEN=abcdef
    • make publish
