CLI/API development

To set up a development environment for the CLI

1. Install go v1.16
2. Install buf
3. make or make unit-tests to ensure everything built correctly.

unit testing

We are using Ginko for our unit tests. To execute the all the unit tests, run make unit-tests.

To run a single test, you will need to set the KUBEBUILDER_ASSESTS environment variable to point to the directory containing our mock K8s objects.

export KUBEBUILDER_ASSETS=$(git rev-parse --show-toplevel)/tools/bin/envtest
go test github.com/weaveworks/weave-gitops/pkg/kube

or

export KUBEBUILDER_ASSETS=$(git rev-parse --show-toplevel)/tools/bin/envtest
cd pkg/kube
go test

Executing a subset of tests

Ginkgo allows you to run a subset of Describe/Context/It specs. See Focused Specs for more information

Setup golangci-lint in your editor

Link for golangci-lint editor integration: https://golangci-lint.run/usage/integrations/

For VSCode, use these editor configuration flags:

    "go.lintFlags": [
        "--fast",
    ],

UI Development

To set up a development environment for the UI

1. Install go v1.16
2. Install Node.js version 14.15.1
3. Make sure your $GOPATH is added to your $PATH in your bashrc or zshrc file, then install reflex for automated server builds: go get github.com/cespare/reflex
4. Go through the Weave GitOps getting started docs here: https://docs.gitops.weave.works/docs/getting-started/
5. Run make node_modules. NOTE: Running npm install could leave you unable to pass our ui-tests. If you're getting an error about a git diff in your package.lock, run rm -rf node_modules && make node_modules.
6. Make sure GitOps is installed on a fresh kind cluster for this repo by running kind delete cluster, kind create cluster, and finally gitops install.
7. To start up the HTTP server with automated re-compliation, run make api-dev
8. Run npm start to start the frontend dev server (with hot-reloading)

Lint frontend code with make ui-lint - using Prettier (https://prettier.io/) will get you on the right track!

Run frontend tests with make ui-test - update CSS snapshots with npm run test -- -u

Check dependency vulnerabilities with make ui-audit

Recommended Snippets

To create a new styled React component (with typescript):

      "}",
      "",

      "  return (",
      "    <div className={className}>",
      "      ${0}",
      "    </div>",
      "  );",
      "}",
      "",
      "export default styled(${1:}).attrs({ className: ${1:}.name })``"
    ],
