- Playwright's [root package.json](../package.json) is **never published to NPM**. It is only used for devmode, e.g. when running `npm install` with no arguments or installing from github.
- Playwright dependencies for all packages are the same and are managed with the [`root package.json`](../package.json).
- Playwright browser versions for all packages are the same and are managed with the [`browsers.json`](../browsers.json).
> **NOTE** As of May 20, 2020, the only exception is the `playwright-electron` package 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`](./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`](./build_package.js) does the following:
- copies certain files and folders from `playwright-internal` to the subpackage (e.g. `//lib`, `//types`, `//LICENSE` etc)
- generates `package.json` and puts it in the subpackage
- generates `browsers.json` and puts it in the subpackage
- uses `npm pack` to 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:
