Creating a Chocolately package for Chromedriver
November 11, 2015
Update: the package is now called chromedriver, and is at
Chocolatey, our new Windows apt-get has now finally reached a stage where it is widely accepted (they get about 25m downloads a month) and thanks to its Kickstarter campaign, stable and close to a version 1 release.
It works using nuget in the background, but instead of using
install-package xyz you would use
choco install firefox.
The biggest problem Chocolatey faces right now is package rot - packages that are out of date in its repository. For example MongoDB is still at version 2 and doesn’t install correctly as a service. The same applies for Redis, and also Chromedriver. For Chromedriver this is frustrating, as Chromedriver updates almost monthly to try to catch up with Chrome’s versions, and typically the old versions of Chromedriver will stop working once Chrome updates itself.
The Chocolatey contributors are aware of this, and are working on a package verifier, however in the meantime I need a way to install Chromedriver in one line rather than 30 lines of hard to maintain Powershell.
My solution was to embark on writing my first Chocolatey package, “chromedriver-latest” - just to add confusion to the Chocolatey repository there are now 3 separate packages. The one I have created will always get the latest Chromedriver however, and unlike other software installers such as MongoDB, Chromedriver is useless unless you have the latest version. Infact it should really be auto-updating but the chances of that happening are fairly slim.
Creating a Chocolatey package
The docs for creating a new package are good, everything is clear and you get a nice bootstrap template by running
choco new MyPackageName.
This generates the .nuspec file for you, and two powershell files. Knowledge of Powershell helps a lot, but the 2 scripts having a long set of examples to get you going.
Once you have written your installer and updated the .nuspec file, create the package using
choco pack .\MyPackage\MyPackage.nuspec and then install it with
choco install MyPackage.1.0.0.nupkg. Finally you can push it to Chocolatey.org using
The package hasn’t yet been improved so it’s not listed publicly, however it is available using
choco install chromedriver-latest -version 1.0.1.
