Field notes
Nine working-developer guides covering Shopware 6 migration, plugin development, headless architecture, the MCP server for AI agents, Elasticsearch/OpenSearch search, the HTTP QUERY method, and the Redis Streams setup that keeps your message queue out of the database. Written from real client projects.
Every guide here started as a real client problem I solved. If a guide is short, that's because the answer is short. If it's long, it's because the topic genuinely needs the depth.
Topics covered: migration (Shopware 5 to 6), performance (Redis Streams for the message queue, Elasticsearch/OpenSearch search, product import work), plugin development (your first plugin, the CLI workflow, the MCP server for AI agents), API development (the HTTP QUERY method and RFC 10008), architecture (headless vs. Twig), and troubleshooting (cache, indexing, plugin conflicts).
Who these are for: Shopware merchants making architecture decisions, and the developers implementing them. If you're stuck and Stack Overflow let you down, start here.
What Symfony 7.4 already supports, a working Store API route with real 6.7.12.2 core code, and the HTTP cache gap nobody mentions.
