Working With This Repo

All packages must contain the following scripts to perform the stated actions:

Package param Command Description
start Runs complete test and build suite and starts the dev server.
serve Runs build suite and starts the dev server. When serving core, takes optional open value as argument to open specific page. (e.g: npm run serve core --open=bot)
build:one <package_name> Runs build suite and outputs the result into dist for the passed package name.
build:all Runs build suites for all of the packages and outputs the result into dist.
test Runs the test suite with eslint, stylelint and jest.
test:jest Runs only the jest test suite.
test:qa Runs the e2e test suite.
test:performance Runs the performance test suite.

Note: Please follow the README of each package you intend to work with on how to get set up and their custom scripts. However, the above scripts can be run from the root directory in the following manner.


Package names

Each package is named with the @deriv/ prefix, however for the scripts above, you do not need to add the @deriv/ prefix as the scripts already prefix the 1st argument of the script with @deriv/. However, if you do use the lerna CLI directly, then you will need to use the full package name including the @deriv/ prefix.

You can find the names of packages by first navigating to the packages folder. Each sub-folder is a package and contains a package.json file. The value of the name key in package.json is the package name.

Usage

Starting a Development Server

If you wish to work on Core, simply run npm run serve core.

But for working on any of the other packages (such as Trader, Bot, P2P), perform the following:

  1. Open 2 terminals.
  2. Run npm run serve {package name} in the first one. e.g.: npm run serve translations, npm run serve bot, etc.
  3. Then run npm run serve core in the second one.

How to Clean Packages

If you intend to remove node_modules folder(s) from the projects, please run npm run clean from the root of the project.

This runs lerna clean && rm -rf $(git rev-parse --show-toplevel)/node_modules under the hood. You can read more on the various lerna commands (and the clean command) over at the Lerna docs.

Note: In case of facing permission denied error, please simply run sudo chown -R $(whoami) . from the root of the project.

How to clear cache

npm cache clean -f


Servable packages

  • account
  • appstore
  • bot-web-ui
  • cashier
  • cfd
  • components
  • core
  • p2p
  • trader

Examples of Script Usage

core is required to run any of the other packages such as if you want to run the bot-web-ui the core must be instantiated before.

npm run serve core

If a script supports the "Package param", you can supply a {package name} for it to run the script in. At the moment, only 1 package name can be given to a script, if you wish to run in multiple, please use the lerna command that's used under the hood as per its docs.

✅ In order to run the bot package, simply run:

npm run serve bot-web-ui

✅ Likewise for trader (or any other package) with a different script:

npm run test:stylelint trader

Release

There are 2 types of release:

  1. Release to staging:
    1. git tag staging_v20191205 -m 'release staging' # the tag needs to follow the RegExp format /^staging.*/
    2. git push origin staging_v20191205
  2. Release to production:
    1. git tag production_v20191205 -m 'release production'
    2. git push origin production_v20191205

There is a 4th type of release: releasing npm registry packages (currently @deriv/p2p). This a WIP, but the current method is:

  1. Acquire membership to @deriv npm organization namespace.
  2. Ensure you have a new (bumped) version of publishable packages (currently @deriv/p2p).
  3. Run npm run publish:p2p. The command publishes all bumped packages. However, right now the name includes the word p2p to signal the WIP status and that P2P is the only published package under this repo.

PR format recommendations

  1. Use the [{Project Code}] {Developer}/{Clickup Card ID}/{Description} format for PR titles. (e.g.: [COJ] evgeniy/COJ-247/Align next-button on mt5 modal), where [COJ] is a clickup project code.
  2. Add screenshots of change for easier reviewing (whenever applicable) and brief description
  3. Use Draft PRs if you don't mean to request for reviews yet. Read more here.

Test link deployment

There are two types of test link deployment preview:

  1. Automatic deployment

Upon creating PR, Vercel will auto-generate a test link inside the PR. you can use that to preview the test link for the changes you have made.

  1. Manual deployment

If preferable to use manual deployment, you can use gh-pages functionality to create a test link. here are ways to do it:

  • You can simply deploy to root of the gh-pages branch with: npm run deploy.
  • You can clean (remove br_ folders and clear root) your gh-pages branch and deploy to root in a single command with npm run deploy:clean
  • You can deploy to a folder in your gh-pages branch in order to separate from root app deployment and other folder deployments with: npm run deploy:folder br_test_folder (folder name must be prefixed with br_))

FAQ

  1. How do I install an npm package in one of our packages?

    A. You can simply cd into the package you wish to install to, then run npm i package-name as usual. Or simply run a lerna exec like lerna exec --scope=local-package -- npm i npm-package-name, e.g.: lerna exec --scope=@deriv/translations -- npm i i18next. Please note that for direct lerna CLI use, you need the full package name including the @deriv/ prefix.

  2. How do I uninstall an npm package from one of our packages?

    A. Just as installing, except the npm command you'd run would be npm uninstall (shortened to npm un). e.g.: lerna exec --scope=@deriv/translations -- npm un i18next.

  3. How do I run npm ci or equivalent to add dependencies based on package-lock.json?

    A. You have two options:

    1. use lerna exec with the --scope argument as the package you want to run the command on, as such lerna exec --scope=trader -- npm ci.
    2. cd into packages/PACKAGE-NAME and run npm ci, as such cd packages/trader && npm ci
  4. My build(s) fail and I can see it related to Node Sass (node-sass), what do I do?

    A. This issue happens when your node-sass has its binding.node set to a version of node different from the current projects' one. Please try the following in order:

    1. First run npx lerna exec -- npm rebuild node-sass and try building your packages again.
    2. If that doesn't work, try npm cache clean --force, followed by npm run clean, and then npm run bootstrap.
    3. And finally, if that doesn't work then you can read deeper into this StackOverflow post.
  5. How can I regenerate package-lock.json file?

    We have added bootstrap:dev to scripts. If you are updating or adding a package and you want to regenerate package-lock.json file, you should run this command npm run bootstrap:dev
