Table of Contents

Requirements

Node, git, and yarn can be installed through homebrew on MacOS. If you need to support more than one version of node at the same time, you can consider installing it though nvm instead of homebrew

Monowhat?

This monorepo is managed with Yarn Workspaces.

Yarn Workspaces allow us to maintain package modularity for javascript projects that have interdependency. Organizationally, they allows us to track issues, pull requests, and progress for all related packages in one place.

Getting started

Debugging the production release

Make sure you have pulled the latest production version.

git pull --tags -f

Check out the latest production release.

git checkout production-release

Run the bootstrap script to build all the libraries and apps. You can use bootstrap:es6 here for a faster build if you don't want to run the tests.

yarn bootstrap

Docker

You can run the code locally in Docker, which avoids needing to install Node or yarn.

git clone git@github.com:zooniverse/front-end-monorepo.git
cd front-end-monorepo
# build first
docker compose build
# run all services in the background (no authentication available)
# app-project at http://localhost:3002/projects/[owner]/[project-name]
# app-root at http://localhost:3003
docker compose up -d
# shut down the running containers when you're finished
docker compose down
# run this if you need a shell inside the running container
docker compose run --rm shell

You can supply a service name (from docker-compose.yml) to docker compose if you only want to run a single service eg.

# only build the project app
docker compose build fe-project
# only run the project app
docker compose up -d fe-project

Development environments for individual packages can be run from the package directories. For example:

cd packages/app-project
docker-compose up

to run a development server for the project app. See the READMEs for individual packages for detailed instructions.

With Node and yarn

Alternatively, you can install Node 20 and yarn and build the monorepo packages.

git clone git@github.com:zooniverse/front-end-monorepo.git
cd front-end-monorepo
yarn bootstrap

The bootstrap script will install the dependencies and build any local packages used as dependencies.

Helpful Guides

Packages

See each package's folder for more specific documentation.

package name folder description
@zooniverse/async-states packages/lib-async-states Frozen object of async states to use in data stores
@zooniverse/classifier packages/lib-classifier Classifier view components and state which can be exported modularly or altogether as a working classifier
@zooniverse/fe-project packages/app-project Server-side rendered application for a project (anything at /projects/owner/display_name)
@zooniverse/grommet-theme packages/lib-grommet-theme The style definitions for a Zooniverse theme to use with Grommet
@zooniverse/panoptes-js packages/lib-panoptes-js Panoptes API javascript client. Functional HTTP request helpers built on top of superagent
@zooniverse/react-components packages/lib-react-components A set of Zooniverse-specific React components, built using Grommet

Conventions

NPM

All packages built from this monorepo should be scoped to zooniverse, e.g. grommet-theme becomes @zooniverse/grommet-theme.

packages directory

Libraries for publishing to NPM should have their directory names prefixed with lib-, e.g. /grommet-theme becomes /lib-grommet-theme.

Apps should have their directory names prefixed with app-, e.g. /project becomes /app-project.

Deployment

Deploys to production and staging are handled by Jenkins using Docker images.

Deployments to a staging Kubernetes instance that uses Panoptes production are triggered by merges to master. This is used for manual end-to-end behavior testing for new code and design reviews. https://frontend.preview.zooniverse.org/projects/:project-owner/:project-name/ proxy redirects to the new NextJS app while the rest of sub-domain redirects to PFE. Staging projects can be loaded by adding this query param to the URL: ?env=staging.

Deployments to a production Kubernetes instance are triggered by committing a production-release git tag on master. This can either be done using the git CLI or using the lita deploy command on slack. https://www.zooniverse.org/projects/:project-owner/:project-name/classify proxy redirects to the new NextJS app while the rest of the domain redirects to PFE. Currently the only project that is configured to do this is Planet Hunters TESS. Eventually more projects will migrate when they migrate to the new classifier.

More information is available in ADR 12 and ADR 17

Deploying Storybook

FEM's storybook can be viewed at https://zooniverse.github.io/front-end-monorepo/.

To deploy the latest version FEM's storybook, make sure you have pulled the latest production version and run yarn bootstrap then yarn deploy-storybook.

Environment variables

  • PANOPTES_ENV: sets which Panoptes API endpoint to use.
    • production will use https://www.zooniverse.org/api
    • staging will use https://panoptes-staging.zooniverse.org/api.

The yarn build scripts default to production for libraries if PANOPTES_ENV is not specified. The apps are always built to the production API.

  • NODE_ENV: the webpack build mode for libraries and the NextJS apps (production, development or undefined.)
  • APP_ENV: the deployment environment, logged as the Sentry environment with errors:
    • development: local development on localhost or local.zooniverse.org.
    • branch: PR branch deploys on fe-project-branch.preview.zooniverse.org.
    • staging: staging on frontend.preview.zooniverse.org.
    • production: the Zooniverse web site, www.zooniverse.org.
  • CONTENTFUL_ACCESS_TOKEN: access token for the Contentful API. Should be kept secret.
  • CONTENTFUL_SPACE_ID: space ID for Zooniverse About pages in Contentful. Should be kept secret.
  • NEWRELIC_LICENSE_KEY: License key for New Relic logging. Should be kept secret.
  • COMMIT_ID: the latest git commit hash. Used for versioning Sentry releases and recorded in classification metadata.

Docker images

  • zooniverse/front-end-monorepo-staging: Built from the Dockerfile in the root directory. It runs yarn install and builds all the libraries and apps from the latest main branch commit.
  • zooniverse/front-end-monorepo-production: Built from the Dockerfile in the root directory. It runs yarn install and builds all the libraries and apps from the production_release tag.

Publishing

When publishing an individual package to npm, first cd into the repo you would like to deploy (within the packages folder), then:

  1. Update changelog and commit
  2. yarn version --major|--minor|--patch --no-git-tag-version (use the desired semvar here)
  3. Update other packages to reference the newly updated package version
    • Ex: If updating lib-react-components to 1.0.0 from 0.7.2
    • lib-classifier should point to the new 1.0.0 version of lib-react-components
  4. git push origin name-of-branch
  5. Merge branch
  6. Checkout master, pull for latest
  7. Build the package with yarn build from the package dir, where available
  8. Publish using npm:
    • Sanity check: if you're using nvm (Node Version Manager), make sure you've switched to the latest version of node/npm
    • Check that you're publishing the correct version by running npm publish --dry-run from the package dir
    • When you're happy, run npm publish from the package dir
    • You can optionally login to npm prior to this using npm login and store an auth token in a .npmrc file
