Markov Chain Plugin

Development

Initial steps

1. Clone this repo and cd into it
2. Run npm install to pull dependencies
3. Run npm start to run webpack-dev-server in development mode with hot module replacement

Run using HTTPS

Additional steps are required to run using HTTPS.

1. install mkcert : brew install mkcert (install using Scoop or Chocolatey on Windows)
2. Create and install the trusted CA in keychain if it doesn't already exist: mkcert -install
3. Ensure you have a .localhost-ssl certificate directory in your home directory (create if needed, typically C:\Users\UserName on Windows) and cd into that directory
4. Make the cert files: mkcert -cert-file localhost.pem -key-file localhost.key localhost 127.0.0.1 ::1
5. Run npm run start:secure to run webpack-dev-server in development mode with hot module replacement

Alternately, you can run secure without certificates in Chrome:

1. Enter chrome://flags/#allow-insecure-localhost in Chrome URL bar
2. Change flag from disabled to enabled
3. Run npm run start:secure:no-certs to run webpack-dev-server in development mode with hot module replacement

Building

If you want to build a local version run npm build, it will create the files in the dist folder. You do not need to build to deploy the code, that is automatic. See more info in the Deployment section below.

Notes

1. Make sure if you are using Visual Studio Code that you use the workspace version of TypeScript. To ensure that you are open a TypeScript file in VSC and then click on the version number next to TypeScript React in the status bar and select 'Use Workspace Version' in the popup menu.

Deployment

Follow the instructions in this Guide to setup an S3 & Cloudfront distribution that can be used with Github actions. See also s3_deploy.sh, and ./github/ci.yml.

Production releases to S3 are based on the contents of the /dist folder and are built automatically by GitHub Actions for each branch and tag pushed to GitHub.

Branches are deployed to http://markov-chain-plugin.concord.org/branch/. If the branch name starts or ends with a number this number is stripped off.

Tags are deployed to http://markov-chain-plugin.concord.org/version/.

To deploy a production release:

1. Increment version number in package.json
2. Create new entry in CHANGELOG.md
3. Run git log --pretty=oneline --reverse <last release tag>...HEAD | grep '#' | grep -v Merge and add contents (after edits if needed to CHANGELOG.md)
4. Run npm run build
5. Copy asset size markdown table from previous release and change sizes to match new sizes in dist
6. Create release-<version> branch and commit changes, push to GitHub, create PR and merge
7. Checkout master and pull
8. Create an annotated tag for the version, of the form v[x].[y].[z], include at least the version in the tag message. On the command line this can be done with a command like git tag -a v1.2.3 -m "1.2.3 some info about this version"
9. Push the tag to github with a command like: git push origin v1.2.3.
10. Use https://github.com/concord-consortium/markov-chain-plugin/releases to make this tag into a GitHub release.
11. Run the release workflow to update http://markov-chain-plugin.concord.org/index.html.
    1. Navigate to the actions page in GitHub and the click the "Release" workflow. This should take you to this page: https://github.com/concord-consortium/markov-chain-plugin/actions/workflows/release.yml.
    2. Click the "Run workflow" menu button.
    3. Type in the tag name you want to release for example v1.2.3. (Note this won't work until the PR has been merged to master)
    4. Click the Run Workflow button.

Testing

Run npm test to run jest tests. Run npm run test:full to run jest and Cypress tests.

Cypress Run Options

Inside of your package.json file:

1. --browser browser-name: define browser for running tests
2. --group group-name: assign a group name for tests running
3. --spec: define the spec files to run
4. --headed: show cypress test runner GUI while running test (will exit by default when done)
5. --no-exit: keep cypress test runner GUI open when done running
6. --record: decide whether or not tests will have video recordings
7. --key: specify your secret record key
8. --reporter: specify a mocha reporter

Cypress Run Examples

1. cypress run --browser chrome will run cypress in a chrome browser
2. cypress run --headed --no-exit will open cypress test runner when tests begin to run, and it will remain open when tests are finished running.
3. cypress run --spec 'cypress/integration/examples/smoke-test.js' will point to a smoke-test file rather than running all of the test files for a project.
