Hi, and welcome to dev.jamovi.org, the developer hub for jamovi.
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
The 2.5 series of jamovi is out. This updates the R version to 4.3.2, and moves the snapshot forward to 2024-01-09.
The 2.5 series improves support for computers using ARM CPUs such as Chromebooks and the new “Apple Silicon” Macs. Note that modules are (typically) not portable between operating systems or architectures, so separate modules will need to be built for each.
You’ll need to update your jmvtools to build against the 2.5 series:
install.packages('jmvtools', repos=c('https://repo.jamovi.org', 'https://cran.r-project.org'))We’ve refined the advanced UI customization in jamovi 1.0.4 and newer. This is not backwards compatible, so we discourage its use in existing modules for the time being (Until the 1.0.4+ is is in broader use). People developing or releasing modules for the first time are encouraged to make use of it. More info here.
We’ve added a new document to our tutorial series describing how jamovi analyses can use state. State is used with longer running analyses, and allows the analysis to re-use results that were calculated previously. This can lead to much faster analyses, and a much nicer user experience.
Read more about state here.
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 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 jus of 1.0 will be
automatically upgraded. Upgraded files will be placed in
tame compilerMode (explained next), you may
want to change it to aggressive.
compilerMode: aggressive vs tamejmvtools 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 compilerMode of 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
aggressive compilerMode, and when you begin to
refine your UI by adding custom changes to your .u.yaml files swap over
to tame 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_home
option.
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
