Automated PHP Stubs Improve WooCommerce Extension Integration

Digital opportunity (v4): WooCommerce Extension Integration Static Analysis Kit Target users: WooCommerce plugin and theme developers who need to ensure their code integrates reliably with other Woo extensions, especially those lacking access to all extension versions or working in resource-constrained environments. How it would work: Provide a step-by-step workflow and checklist for setting up PHPStan with the new woocommerce/php-stubs package. This enables developers to statically analyze their integration code for compatibility with specific Woo extensions and versions, without installing each extension. The kit includes sample configuration files and usage instructions. First version: A downloadable PDF and markdown checklist with setup steps, sample composer and PHPStan configuration snippets, and troubleshooting tips. Distributed via a GitHub repository managed by a small team of WooCommerce community contributors. Pilot with up to 10 developers integrating with at least 3 different Woo extensions over 4 weeks. Alternatives to investigate: Manual stub creation for each extension; using only WooCommerce's own stubs; relying on runtime testing without static analysis; or using other static analysis tools that may not support stubs. Difference to test: Whether the kit enables faster and more reliable detection of integration errors compared to manual stub management or runtime-only testing. Measure reduction in class.notFound errors and time spent on setup. Source evidence of a capability or need: We’re introducing woocommerce/php-stubs , a new package that auto-generates PHP stubs for Woo extensions, both from the WooCommerce Marketplace and WordPress.org, so PHPStan can Possible uses and limits: The availability of the stubs package suggests a need for better integration testing among WooCommerce developers. The kit addresses the practical challenge of static analysis for extension integration, but actual adoption and effectiveness require further investigation. Potential users and optional payers: Unverified analysis, not established facts; confirm before acting. No established paying customers. This is a non-commercial community tool for developer support. No monetization required for this project. Competitors and alternatives to check: Unverified analysis, not established facts; confirm before acting. Manual stub management, WooCommerce's own stubs, and alternative static analysis tools. Effectiveness and coverage of these alternatives should be compared during the pilot. Optional legal business model: Proposed hypothesis; revenue may never occur. Monetization is not required for this project. No commercial hypothesis is established. The kit is intended as a free resource for the community. Skills and time to test: Skills: PHP development, static analysis, documentation. Time: 1-2 days for checklist creation, 4 weeks for pilot. Not verified; actual time may vary by participant experience. Geographic availability and limits: Unverified analysis, not established facts; confirm before acting. The source names WooCommerce Marketplace and WordPress.org as extension sources; global developer coverage is unknown and must be checked locally. Legal and platform constraints to verify: Unverified analysis, not established facts; confirm before acting. Local privacy, licensing, and intellectual-property terms for using and distributing PHP stubs and documentation must be verified. No legal advice is given. Current prices and platform terms: Unverified analysis, not established facts; confirm before acting. Prices and terms for woocommerce/php-stubs and PHPStan are unknown/not checked. All tools are reported as public or open source, but local verification is required. Age, payments and eligibility checks: MLAIEL requires age 16 or older; external eligibility and payments are unverified. Minimum user age is 16 per MLAIEL. Any external service's higher age limit, KYC, country coverage, payout, payment, and tax eligibility are unverified until checked. Smallest low-cost validation test: A single developer follows the checklist to set up PHPStan with woocommerce/php-stubs for one integration. Measure time to first successful static analysis and number of errors detected. No cost beyond developer time. Human responsibilities: Community contributors draft and update the checklist, test the workflow with real integration scenarios, and collect feedback from pilot users. Developers follow the checklist and report issues. AI contribution and limits: Optional: Use AI to scan integration code for missing stubs or suggest configuration improvements. AI is not required for the core workflow but could assist in documentation or troubleshooting. Data and access needed: Access to the woocommerce/php-stubs package, sample WooCommerce extensions, and representative integration code. No private data required. User feedback and error logs (with consent) for validation. Source-supported setting and capacity: We’re introducing woocommerce/php-stubs , a new package that auto-generates PHP stubs for Woo extensions, both from the WooCommerce Marketplace and WordPress.org, so PHPStan can check calls into other extensions instead of skipping them. Ordered steps and owners: 1. Contributor drafts and reviews the checklist. 2. Developers follow setup steps using woocommerce/php-stubs. 3. Developers run PHPStan and record errors and setup time. 4. Collect feedback and update the checklist as needed. Minimum resources and dependencies: Existing woocommerce/php-stubs package, PHPStan, Composer, sample integration code, GitHub for distribution, and basic documentation tools. Confirm access to all required software versions. Costs and affordability unknowns: Actual costs are unknown and require local quotes. All tools used are open source or free for development. No paid infrastructure required for the pilot. How a newcomer can help: Community contributors (1-2) draft and maintain documentation. Developers (up to 10) participate in the pilot by following the workflow and reporting results. Beginners can follow the checklist under supervision. Pilot and success criteria: Proposed pilot target: 10 developers, 3 extensions each, 4 weeks. Baseline: number of class.notFound errors and setup time before using the kit. Success: 80% reduction in errors and 30% faster setup, measured by user logs and surveys. Risks and safeguards: Stubs may not cover all extension features or edge cases. Developers may misconfigure PHPStan or the stubs. Documentation may become outdated if the stub package changes. Legal or licensing issues may arise if local rules restrict stub use. When to stop or change direction: If pilot users report no measurable reduction in errors or setup time, or if stubs are found to be incomplete/incompatible, pause and revise the workflow.
