Here you will find resources that cover the development of analyses for jamovi (and R). It’s still a work in progress, and we’ll be adding to it over time, but the current tutorial series has everything you need to get up and running.
There are forums available at forum.jamovi.org, so if you have questions about developing modules for jamovi, or feedback on how we can improve the developer hub, we’re keen to hear from you there.

For those interested in the jamovi platform, it is hosted on GitHub here. Don’t forget to ‘star’ us!
Tutorial: Getting Started
We’ve just released a beta of jamovi 0.7.3 (available from here), which brings some significant improvements, and minor changes to developing jamovi modules. In order to continue developing, we encourage you to download and begin using the new jamovi beta, and the latest version of jmvtools.
In the past, we’re had a number of difficulties with dependency resolution for jamovi modules. Sometimes jmvtools would install more dependencies than were necessary, and other times not enough. This stemmed from contamination of the R library path, from R packages installed on the system. In this release we’ve successfully isolated the system libraries from the jmvtools, and only the required dependencies will now be installed.
Previously, .u.yaml files (the UI definition) were automatically generated from .a.yaml files (the analysis definition). This was sometimes problematic when additional changes were made to the .a.yaml files. It wasn’t always clear which changes should be propagated to the .u.yaml files, and which should not.
In the 0.7.3, the .a.yaml and .u.yaml files work together. The .u.yaml file, by default, contains minimal information (mostly just describing the layout), and the property values, for example labels, are taken directly from the .a.yaml file. For many people, they will only need to edit the .a.yaml file, and jmvtools can take care of the .u.yaml file itself. More documentation for UI Design will be coming soon.
.u.yaml files using this new scheme will have the
jus, near the top of the file, specified as
2.0. .u.yaml files using the older
1.0 will be automatically upgraded. Upgraded files will be placed in
compilerMode (explained next), you may want to change it to
compilerMode: aggressive vs tame
jmvtools also introduces a new option in .u.yaml files:
compilerMode. By default, .u.yaml files are created in
aggressive mode. This means that jmvtools will take a heavy handed approach when updating the .u.yaml files. If new options are added to the .a.yaml file, it will aggressively add them into the .u.yaml file, overwriting any manual changes.
In contrast, the
tame does not overwrite manual changes in the u.yaml. The trade off is that it often can’t position UI elements as optimally.
We recommend beginning with your .u.yaml files in
compilerMode, and when you begin to refine your UI by adding custom changes to your .u.yaml files swap over to
compilerMode so that your changes are preserved. Again, for a lot of people,
aggressive mode will be all that they will ever need.
For the time being, changes to the .a.yaml and/or the .u.yaml files, will still require you to shut jamovi down and restart it before you’ll see the changes to the UI. We hope to fix this issue in the next few weeks.
On windows, jmvtools is still not able to find the jamovi installation by default. You will still need to pass the
home option, or set the
jamovi 0.7.2.7 Adds dev mode, providing a stack trace when an analysis errors for whatever reason. The tutorial has been updated to describe this: Debugging an Analysis
