Snippets
Small, tested pieces of Apex and LWC I have needed more than once.
Every snippet here has run in a real org. Copy them, but read them first — a governor limit is context-dependent, and so is a bulkification strategy.
A debounced search input in LWC
Three hundred milliseconds of patience, and one fewer race condition.
Walking an account hierarchy in a fixed number of queries
Five levels, five queries, and a guard against the cycle somebody will eventually create.
A callout with a timeout you chose
Named Credentials, an explicit timeout, and an error you can act on.
