This is an open repository of jsPsych plugins and extensions developed by members of the jsPsych community. If you've written a jsPsych plugin or extension that you think others might be interested in using, this is the place to share it!
Plugins and extensions in the main jsPsych repository are maintained by the core jsPsych team.
The team takes responsibility for fixing bugs and updating plugins to take advantage of new features in jsPsych.
Plugins and extensions in this jspsych-contrib repository are contributed by community members.
They are not extensively tested or verified by the core jsPsych team, and there is no guarantee that anyone will be available to fix bugs, push updates, or answer questions about these plugins/extensions.
However we would encourage contributors to respond to issues/questions and to maintain their code.
Contributions to jspsych-contrib that are broadly useful, well-documented, and well-tested may be added to the main jsPsych repository, with the contributor's permission.
The jsPsych plugins that have been contributed by community members can be found in the /packages directory.
The /packages directory also contains four template sub-folders that can be used as a starting point for contributing a plugin/extension (see the Guidelines for contributions section).

Contributions to this repository must:
- Work as described
- Include the complete code for the plugin or extension.
- Include a
readme.mdfile following our template. - Include a
package.jsonfile.
Optionally, contributions can include:
- A
/docsdirectory with documentation matching the template for docs on jspsych.org - An
/examplesdirectory with a working.htmldemo. - A test suite following the testing framework in our
-tstemplates.
To submit a contribution, open a pull request that contains a directory for your plugin/extension inside the /packages directory.
In the pull request comments, please make it clear how we can verify that the contribution is functional.
This could be accomplished with a link to a demonstration experiment, the inclusion of an example file and/or testing files, or through some other means.
We try to review pull requests quickly and add new contributions as soon as the minimal standards are met.
After cloning this repository, run npm install and then npm run new.
This will prompt you through the process of creating a new plugin or extension.
The tool will create a new directory in the /packages directory with the appropriate files and names.
You may want to read the jsPsych documentation on plugin development to understand how to work with the index.tsfile (for TypeScript development) and index.js file (for JavaScript development).
This template uses TypeScript source files that are complied into JavaScript using Node.js and npm.
This is the format used for plugins in the main jsPsych repo.
To use this template, you should edit the src/index.ts file, keeping the overall structure but changing the details as appropriate (parameters, trial method, etc.).
You can then use the npm run build command to compile your index.ts code into JavaScript files, which will appear in a /dist directory.
This format also allows you to add a Jest test file (optional).
For more details, including setup instructions and detailed explanations of files, please see the jsPsych documentation page: Configuring the jsPsych development environment.
You can also read the plugin development documentation and look at the plugin/extension folders in the main jsPsych repository /packages directory for more examples.
