Offering to maintain Redoc Field Formatter

Problem/Motivation

I am a long-time Drupal contributor working for Pronovix. We build and maintain developer portals for enterprise organizations, and we heavily rely on the redoc_field_formatter.module to render OpenAPI/Swagger documentation.

Currently, the module is blocked from being used on modern stacks and is functionally broken due to a lack of active maintainership (the last stable release was in early 2023). Specifically, two critical issues have stalled for a prolonged period, causing bottlenecks for the community:

• #3434151: Automated Drupal 11 compatibility fixes for redoc_field_formatter: This issue was created over 2 years ago and has been sitting in Needs review for over a year. While the new 2.0.0 version of the mglaman/composer-drupal-lenient plugin allows pulling in the module's code via Composer, Drupal/Drush doesn't allow enabling the module without the Rector change in the .info.yml file. This blocks upgrades to Drupal 11 for 200+ reporting sites.
• #3263680: Support usage of self-hosted Redoc JS: This feature request has been open for over 4 years. On-prem customers running their sites on their sealed intranet cannot use the module because it forces a hardcoded external CDN asset. Additionally, because that external third-party CDN link broke recently (see #3557964: external library referanced in the module doest resolve), the module is now entirely non-functional out of the box, even for standard installations.

To ensure this module remains viable, secure, and fully compatible with Drupal 11, I, as a Pronovix employee, am prepared to step up, take over project maintainership and support the project moving forward.

Steps to reproduce

1. Attempt to run composer require drupal/redoc_field_formatter on a Drupal 11 project. Composer will fail due to core version constraints in composer.json.
2. If mglaman/composer-drupal-lenient:2.0.0 is also present, therefore it allows Composer to install the module, Drupal/Drush will still fail to enable it due to core version constraints in redoc_field_formatter.info.yml.
3. Install the module on a Drupal 10 site and attempt to render an API specification. The browser console will display a 404 error because the hardcoded external jsDelivr bundle URL no longer resolves.

Proposed resolution

I am offering to take over project maintainership of redoc_field_formatter.module. Once granted access, I will make sure:

• The pending Drupal 11 compatibility fixes #3434151: Automated Drupal 11 compatibility fixes for redoc_field_formatter will be reviewed, tested and commited.
• The self-hosted Redoc JS support #3263680: Support usage of self-hosted Redoc JS will be reviewed, tested and committed to clean up the broken external library reliance.
• The module will get maintenance, issue triage, and stable releases for the community.

Remaining tasks

• Wait 14 days for the current maintainers to respond to this offer.
• If there is no response, move this issue to the Drupal.org project ownership queue for site moderators to process the transition.
• Project moderators contact current maintainers.
• Wait 14 days for the current maintainers to respond.
