MetacatUI is a JavaScript application that provides a user interface for the DataONE network of data repositories. It is built using the Backbone.js framework and the RequireJS module loader. MetacatUI is designed to be a modular, extensible, and customizable application that can be used to build a variety of data repository interfaces. The application is built using a set of Backbone models, collections, and views that interact with the DataONE REST API to provide a user-friendly interface for uploading, documenting, searching, viewing, and downloading data packages.
More about MetacatUI can be found in the MetacatUI documentation site, including installation instructions.
- Fork the MetacatUI repository on GitHub.
- Clone your forked repository to your local machine using
git clone {your-forked-repo-url}
. - Install dependencies using
npm install
to set up your development environment. - Configure your local instance to point to a test DataONE repository by
editing the
config.js
file in thesrc/config
directory:MetacatUI.AppConfig = { root: "/", theme: "arctic", baseUrl: "https://dev.nceas.ucsb.edu", d1CNBaseUrl: "https://cn-stage.test.dataone.org/", metacatContext: "knb", };
- Start the development server using
npm start
and navigate tohttp://localhost:3000/
to view the application.
- Document your plans by creating or adding to an issue

to ensure all tests pass, including any new tests you add for your functionality. - Check that the doc site will build using
npm run jsdoc-dry-run
to make sure there are no JSDoc warnings. - Commit your changes and push your branch to your forked repository.
💡 You may wish to automate steps 9 to 12 in your IDE
- On GitHub, create a pull request to the
develop
branch of the main MetacatUI repository.- Summarize the changes made in the pull request description.
- Our team will review your pull request. We may request changes to ensure quality before approval.
- Once reviewed and approved, your contributions will be merged into the
develop
branch by our team, and you’re done! 🎉
While there has been significant variability in the coding styles applied historically in MetacatUI, we are committed to standardizing our codebase to
improve readability, maintainability, and consistency and to facilitate contributions from the community. With this goal in mind, we have adopted a defined set of coding conventions and tools to enforce these standards. All new or modified code should adhere to these conventions such that the codebase can gradually be brought into alignment with these standards.
We use Prettier to enforce consistent code formatting
with the configuration in the .prettierrc
file. To run prettier manually, use
npm run format
to automatically fix formatting issues or npm run format-check
to check for formatting issues. Pull requests will automatically
check for formatting issues and suggest fixes.
We use ESLint to enforce code quality and style issues. Our ESLint configuration is based on the Airbnb style guide with modifications to support our current AMD/RequireJS module pattern. As we work to adopt newer JavaScript standards, we may need to adjust our ESLint rules to support these changes. We encourage contributors to follow the ESLint rules as closely as possible when modifying existing code or adding new code.
To run ESLint manually, use npm run lint
to see linting issues. Alternatively,
run npx eslint your-file.js
to lint a specific file. Pull requests will
automatically be check for linting issues on changed code and suggest fixes.
Unit and integration tests. MetacatUI has a full suite of unit tests and
integration tests in the tests
subdirectory. Any new code developed should
include a robust set of unit tests for each public method, as well as
integration tests from new feature sets. Tests should fully exercise the feature
to ensure that it responds correctly to both good data inputs and various
classes of corrupt or bad data. All tests should pass before submitting a PR or
merging to develop
.
Tests are automatically run via GitHub Actions. Check the root README.md
file
for this GitHub Actions status badge and make sure it says "Passing":
Read more documentation about how tests are run and viewed in /test/README.md
All JavaScript code should be fully documented with JSDoc comments. Pull requests will automatically checked for complete JSDoc comments.
When documenting code, please follow these guidelines:
For Models and Views:
- Gives a brief overview of what the class / file does and give a few short example of how you might use the class / file.
- Create a screenshot of the View and use the
@screenshot
tag to include it in the built docs. - Use the
@classcategory
tag to organize the class file in the built docs navigational menu
For Model and View methods:
- Say what each class method does and how to use it (use
@param
and@returns
) - Use
@example
tags to give examples of parameters and return values - Use
@fires
to indicate Backbone Events that are fired by a method
For Model and View attributes:
- Describe the purpose of the attribute, its
@default
value, and one or more@example
s
For everything:
- Use the
@since
tag to indicate the version the class/method/attribute was added - Use
@deprecated
for deprecated APIs and features - Use
@link
to link to other JSDoc pages when mentioning other classes, attributes, and methods (e.g.{@link Model#method}
)
Before merging a feature branch to the develop branch, build the MetacatUI documentation website and make sure that your documentation is displaying correctly and is thorough.
Things to check:
- There are no JSDoc build errors or warnings
- The class shows up in the right category in the class navigation menu
- All class methods and attributes are documented and displaying correctly
- Screenshots of views are displaying correctly
When submitting a Pull Request to MetacatUI, it's essential to adhere not only to the above criteria on tests, formatting, and documentation, but also to additional aspects that ensure the quality and functionality of your contributions. Here are key points that reviewers will check during the code review process:
-
Theme Compatibility: Test your changes across all standard themes included in MetacatUI (such as
arctic
,dataone
,default
,knb
) and those in the metacatui-themes repository (drp
andsctld
). This ensures consistency and compatibility across different visual presentations. -
Responsive Design: Ensure that your changes perform well on various screen sizes, including mobile devices.
-
Component Impact Analysis: If you modify an existing model, collection, or view, review all instances where that component is utilized within MetacatUI. This is crucial to prevent unintended impacts, especially considering that our test coverage is not yet exhaustive.
-
Performance Consideration: Be mindful of the performance implications of your changes. This is particularly important for substantial additions, as we aim to maintain or improve the current performance levels of MetacatUI.
-
Error Handling and Messaging: Incorporate robust error handling in your code and ensure that any error messages are clear and user-friendly. If one component triggers an error for any reason, it should not disrupt the functionality of the entire application.
-
Dependency Management: When adding or updating dependencies, evaluate their necessity and impact on the project size. Avoid redundancy and prefer dependencies with a strong maintenance history and a large supporting community, as this increases the likelihood of long-term support.
-
User Status Consideration: If applicable, test the functionality of your changes for both signed-in and non-signed-in users.
-
Documentation Updates: In addition to updating JSDocs, if your changes affect any aspect covered in the MetacatUI guides (
docs/guide
), make the necessary updates. For significant features requiring configuration by MetacatUI administrators, consider adding a new guide. -
Security Assessment: Ensure that any security implications of your changes are thoroughly considered and addressed.
Our development workflow is organized through the git repository and follows a structured branching and release strategy.
main. Releases are merged from the develop
branch to the main
branch,
and the resulting commit is tagged with the release tag (e.g., 2.4.0
). The tip
of the main
branch always reflects the most recent release of the software.
The version number in all configuration files and the README on the main
branch follows semantic versioning and should always be
set to the current release version, for example, 2.8.5
.
develop. The develop
branch is a stable branch that is constantly
maintained in a state ready for release. Commits should only be pushed to this
branch once they are ready to be deployed to production immediately after being
pushed. Any unreleased code changes on the develop branch represent changes that
have been tested and staged for the next release. The tip of the develop branch
always represents the set of features that have been staged for the next
release. Commits are added to the develop branch via a pull request or after
consultation with the designated MetacatUI product owner.
feature. to isolate development on a specific set of capabilities,
especially if it may be disruptive to other developers working on the main
develop
branch, feature branches should be created.
Feature branches are named as feature-
+ #{issue}
+ -{short-description}-
.
With {issue}
being the Github issue number related to that new feature. e.g.
feature-#1456-new-search
.
All feature-*
branches should be frequently merged with changes from develop
to ensure that the feature branch stays up to date with other features that have
been tested and are awaiting release. Thus, each feature-*
branch represents
an opportunity for integration testing of the set of features intended to work
together for a particular release.
dev-X.X. Development branches named after their minor version number can be used when a patch release needs to be created that is behind the main develop branch.
bugfix. A final branch type are bugfix
branches, which work the same as
feature branches, but fix bugs rather than adding new functionality. Bugfix
branches are named similarly, following the pattern: bugfix-
+ {issue}
+
-{short-description}
, with {issue}
being the GitHub issue number related to
that bug. e.g. bugfix-83-fix-name-display
.

- Our release process starts with integration testing in a
develop
branch. Once all changes that are desired in a release are merged into thedevelop
branch, we run the full set of tests on a clean checkout of thedevelop
branch. - After testing, the
develop
branch is merged to main. - Then the
main
branch can be tagged with the new version number (e.g.2.11.2
). We use semantic versioning for version numbers. - Releases can be downloaded from the Github releases page for the MetacatUI repository.
