Available Scripts

In this directory, you can run:

npm run build

This script builds all of the Blockly plugins in this repo.

npm run clean

This script runs npm run clean on each of the Blockly plugins. In general, clean deletes the /build and /dist folders in these plugins.

npm run deploy

This script packages each of the plugins's test playgrounds and deploys them to gh-pages. You can browse these plugin playgrounds at: https://YOURUSERNAME.github.io/blockly-samples/.

npm run deploy:upstream

This script is similar to npm run deploy but it deploys the plugins to blockly-samples upstream. You can browse these plugin playgrounds at: https://raspberrypifoundation.github.io/blockly-samples/.

npm run license

This script runs the js-green-licenses checker on all of the Blockly plugins. Run this script before release to make sure none of our plugin dependencies use packages with non-green licenses.

npm run lint

This script runs npm run lint on each of the Blockly plugins in this repo.

npm run lint:fix

This script runs lint with the --fix option on each of the Blockly plugins in this repo.

npm run test

This script runs npm run test on each of the Blockly plugins in this repo.

npm run test:ghpages

This script builds all files needed to deploy plugins and examples to GitHub Pages, then starts a local server with that content.

npm run test:ghpages:beta

This script installs a beta version of Blockly, builds all files needed to deploy plugins and examples to GitHub Pages, then starts a local server with that content.

Publishing scripts

Note that publishing via the command line is not preferred. You should use the GitHub Action workflow whenever possible, which can handle publishing all plugins as well as recovering from the partially-published state (publishing unpublished plugins only).

Note that none of these scripts will handle npm authentication. You need to configure an npm authentication token before you can use these scripts.

Full publishing documentation can be found in the internal team documentation.

npm run publish:prepare

This script will clone a copy of blockly-samples to a directory called dist, run npm ci, then build and test all plugins.

If any plugin fails to build or some tests fail, this script should fail. Since nothing has been pushed to npm or github, you can simply correct the error and try again.

This script will be run automatically before any of the other publish scripts, so you do not need to run it manually first.

npm run publish:manual

This script will first run npm run publish:prepare. It will publish all of the changed plugins since the last release, using the dist directory. It runs the lerna command that uses conventional commits to determine a new version number for each plugin, and publishes the new versions to npm and to a github release and tag.

If there is some error with npm while running this command, you may end up in a state where some plugins have been published to npm and not others, after lerna has already tagged the new releases. You can recover from this state by fixing the error, and then running either npm run publish:unpublishedOnly or npm run publish:force.

npm run publish:unpublishedOnly

This script will first run npm run publish:prepare. It uses the dist directory created in that script. It uses lerna to check each plugin to see if the version in package.json matches the version on npm. If a version is not yet on npm, it will publish that plugin without updating its version number. Thus, this script should only be used after lerna version has been run in some form (most commonly, during a run of npm run publish:manual that subsequently failed).

If this script fails, correct the error and re-run npm run publish:unpublishedOnly.

npm run publish:force

This script will first run npm run publish:prepare. It will use lerna to force publish all packages, even those that have not changed. You can use this if you run into publishing problems to recover from error states, but you should prefer to use npm run publish:unpublishedOnly if possible.

npm run publish:checkVersions

This script will first run npm run publish:prepare. It will run lerna version to generate the new version numbers using conventional commits that would be created during a full publish action, but it will not actually push the changes nor create any tags. This can be used to check which plugins would be published and under what versions. Note to get accurate results with lerna version you must have the latest tags pulled. This is taken care of by the publish:prepare script.

Other Scripts

npm run deploy:prepare

This script prepares each of the plugins for deployment. In general, the script cleans and builds the src and test directories of each plugin.

You shouldn't need to run this script directly, instead it is run by npm run deploy and npm run deploy:upstream.

npm run prepare-examples

Run this script to copy the entire contents of the installed blockly package and to copy each local @blockly/* plugin's dist/ output (if present) into examples/lib/ so example test pages can reference those packages. This is run automatically before deploying to GitHub Pages. To view an example test page on your file system, run this command manually first.
