This patch starts downloading FFMPEG like we download our browsers instead of bundling it in the NPM package. With this patch, NPM size is reduced from 8.8MB to 1.7MB. Consequences: - `npx playwright` is drastically faster now - playwright driver for language bindings is way smaller - projects that bundle Playwright can pass Apple Notorization Fixes #5193
Managing and Publishing Playwright Packages
Overview
- Playwright ships multiple packages to NPM. All packages that are published to NPM are listed as folders under
//packages/. - Playwright's root package.json is never published to NPM. It is only used for devmode, e.g. when running
npm installwith no arguments or installing from github. - Playwright dependencies for all packages are the same and are managed with the
root package.json. - Playwright browser versions for all packages are the same and are managed with the
browsers.json.
Note
As of May 20, 2020, the only exception is the
playwright-electronpackage that doesn't follow the pack and is published manually. This is due to it's pre-1.0 status.
Building NPM package
To build a package that will be shipped to NPM, use //packages/build_package.js script.
The script populates package folder with contents, and then uses npm pack to archive the folder.
As of May 20, 2020, //packages/build_package.js does the following:
- copies certain files and folders from
playwright-internalto the subpackage (e.g.//lib,//types,//LICENSEetc) - generates
package.jsonand puts it in the subpackage - generates
browsers.jsonand puts it in the subpackage - uses
npm packto pack the subpackage folder - removes all the files that were added during the process
To build playwright package and save result as ./playwright.tgz file:
$ ./packages/build_package.js playwright ./playwright.tgz
To debug what files are put into the folder, use --no-cleanup flag and inspect the package folder:
$ ./packages/build_package.js playwright ./playwright.tgz --no-cleanup
$ ls ./packages/playwright # inspect the folder
Testing packages
To test packages, use //packages/installation-tests/installation-tests.sh.
Publishing packages
All package publishing happens exclusively over CI/CD using the //utils/publish_all_packages.sh script.
Special handling for playwright-electron
playwright-electronversion is pre-1.0.0 and thus managed separately. It's specified inside the//packages/build_package.jsfile.playwright-electronis published manually.
To publish a new version of playwright-electron:
- Bump
playwright-electronversion inside//packages/build_package.js - Submit PR with the updated version
- Build package with
./build_package.js playwright-electron ./playwright-electron.tgz - Publish package with
npm publish playwright-electron.tgz
