Web Programming and Streaming Data in Haskell - Part 1 of 2
summary
Part one stays concrete: it covers the Conduit library and shows runnable examples (use Stack and the slides URL). Demonstrations include a pure sum, a file copy that uses ResourceT to guarantee cleanup, streaming CSV/HTTP body generation, UTF‑8 decode that throws via Conduit when invalid, an average that fails until rewritten with zipSink to run two consumers in lockstep, and printed interleaving that proves yield/await execution. Also mentions Yesod and Conduit as the two domains and provides exercises.
