  • createRoot is the whole React 18 opt-in

    Note2 min read

    Upgrading the package changes almost nothing; replacing render with createRoot is what switches the application into concurrent mode. Leaving the old call in place is a supported and…

  • A moved block renames without destroying

    Note2 min read

    Renaming a resource or moving it into a module makes Terraform plan a destroy and a create, and 1.1 lets the rename be declared instead. The value over…

  • Concurrent rendering is not a feature you turn on

    Deep dive14 min read

    18 in March, after two years of alpha, and createRoot is the whole opt-in. Then a fortnight of consequences.

  • Full-text search that did not need a search engine

    Deep dive9 min read

    A dispute, and a log that recorded that something changed. “Order updated” with no before, no after and no actor.

  • A foreign key is an index you did not have to name

    Note1 min read

    InnoDB requires an index on the referencing column and creates one silently if none exists, which is convenient and produces indexes nobody chose. The auto-created index is a…

  • Types are gone, four years after the deprecation

    Note1 min read

    Mapping types were deprecated in 6.0, made single-only in 7.0 and removed entirely in 8.0, which is an unusually long and well-signposted removal. The four-year runway means most…
