The cypress
NPM package consists of two main parts:
- The
cypress
NPM package.tgz
(built fromcli
)- Contains the command line tool
cypress
, type definitions, and the Module API. - End users install this via NPM to the project's
node_modules
.
- Contains the command line tool
- The "binary"
.zip
(built frompackages/server
)- Contains the Electron app,
ffmpeg
, and built versions of theserver
,desktop-gui
,runner
,example
project, andextension
- Also contains all the production dependencies of the above.
- This is installed when the
cli
is installed or whencypress install
is run, to a system cache.
- Contains the Electron app,
This guide has instructions for building both.
⚠️ Note: The steps in this section are automated in CI, and you should not need to do them yourself when going through the release process.
Building a new npm package is two commands:
- Increment the version in the root
package.json
yarn lerna run build-cli
The steps above:
- Build the
cypress
npm package - Transpile the code into ES5 to be compatible with the common Node versions
- Put the result into the
cli/build
folder.

The npm package requires a corresponding binary of the same version. In production, it will try to retrieve the binary from the Cypress CDN if it is not cached locally.
You can build the Cypress binary locally by running yarn binary-build
, then package the binary by running yarn binary-package
. You can use Linux to build the Cypress binary (just like it is in CI) by running yarn binary-build
and yarn binary-package
inside of yarn docker
.
If you're on macOS and building locally, you'll need a code-signing certificate in your keychain, which you can get by following the instructions on Apple's website. Also, you'll also most likely want to skip notarization since it requires an Apple Developer Program account - set SKIP_NOTARIZATION=1
when building locally to do this. More info about code signing in CI.
yarn binary-zip
can be used to zip the built binary together.
If you want to speed up the time it takes to package the binary, set V8_SNAPSHOT_DISABLE_MINIFY=1
If you are on an M1, you need to set RESET_ADHOC_SIGNATURE=1
in order to be able to actually run the binary after packaging it.
