This repository contains the frontend code. Other repositories are:

Setting up editor

Prettier

This repository uses prettier to keep the code consistent and formatted. You can config your favourite editor by the following links

  • Atom users can simply install the prettier-atom package and use Ctrl+Alt+F to format a file (or format on save if enabled).
  • Visual Studio Code users can Search for Prettier - JavaScript formatter.

Prerequisite

  1. Install asdf version manager
  2. asdf install to install the required tools from .tool-versions
  3. yarn install (brew install yarn if required).

Local development

  1. yarn start
  2. Open https://localhost:3000?filters=%7B%22date__gte%22%3A%5B%7B%22label%22%3A%222020-04-01%22%2C%22value%22%3A%222020-04-01%22%7D%5D%7D of e.g. changeset#91638199
    • The app runs with https; Firefox is recommended since it allows self signed certificates.
    • The staging database does not have all the changesets that production has, therefore the filter is needed.

To also edit the part of the UI that is provided by the OSM Changeset Viewer

Checkout https://github.com/osmlab/changeset-map in a sibling folder.

In ./changeset-map:

  1. yarn link
  2. yarn build --watch

In ./osmcha-frontend

  1. yarn link "changeset-map"
  2. yarn start

Edits in both projects will result in a rebuild and reload the browser.

When finished, reset "osmcha-frontend" back to the npm version of "changeset-map" with yarn add changeset-map@latest

Local testing

Test the application before commiting any changes. If you encounter any error make sure you have watchman installed. Installation Guide.

yarn test

Deploy/Release

  • There are three stacks to deploy to
  • yarn deploy:dev deploys it to mapbox.github.io (currently broken)
  • yarn deploy:staging deploys it to staging.osmcha.org
  • yarn deploy:prod deploys it to osmcha.org

  1. Run the tests with yarn test

  2. (optional) before deploy, you might want to increment the version number of application.

    • We use minor for all non-drastic changes.
    • The patch is reserved for minor changes.
    • We try to stick to sem-ver.
    npm version minor

  3. Then build the app with the following command.

    yarn build:<stack>
    • here stack could be dev, staging, prod. Refer to package.json for more info.

  4. The next step involves deploying the build folder to github. If you get an error like this error: failed to push some refs to 'git' while doing the deploy step. Run rm -rf node_modules/gh-pages/.cache/.

    yarn deploy:<stack>
    • here stack could be dev, staging, prod. Refer to package.json for more info.
    • oh-pages branch handles the build for staging, prod stacks.
    • gh-pages branch handles the build for dev stack.

  5. (optional) If you want to see the new changes on a staging or prod stack. You will need to draft a new github release. The convention is to append -staging or -production or just -server to the current version tag for the server to consume the build and separate concerns.

    • for eg. if the version npm module version was v0.16.3.
    • draft a github release with a tag v0.16.3-staging. (Note the name spacing)
    • supply this version tag to the server.
    • Refer to githubs article for creating releases.
