keystroke

a timer-boxed writing app. pick how long you have, write in markdown, and when the clock hits zero your post ships through a hook you provide. no extensions, no drafts rotting in a folder. the deadline is the editor.

how it works

1. you point keystroke at an executable (the hook)
2. you pick a duration: 10, 15, 30, 45, or 60 minutes
3. you write, with an optional live markdown preview
4. at zero, keystroke writes your post to a markdown file and runs your hook with it

the hook is required. keystroke will not let you write without one, because a post with nowhere to go is just a draft.

examples

install

requires node >= 20.

git clone https://github.com/iteratedcomputing/keystroke.git
cd keystroke
npm install

run

just trying it out? start with the bundled word-count hook, which counts your words and publishes nothing:

make demo

for real use, create a hook (any executable works). start from the word-count example and overwrite it with your own publishing logic:

cp hooks/wordcount.sh hook
chmod +x hook

then start the app and open http://localhost:7777:

make dev

your hook stays yours: ./hook and hooks/local/ are gitignored, so personal hooks never end up in the repo. set KEYSTROKE_HOOK to use hooks anywhere else, and PORT to change the port.

the hook

your hook receives the finished post as a markdown file path in $1, plus KEYSTROKE_TITLE, KEYSTROKE_SLUG, and KEYSTROKE_DURATION_MINUTES in the environment. exit 0 means published; anything else surfaces the failure in the ui with your draft path so nothing is lost.

chain hooks by separating paths with colons. they run in order, and each must exit 0 before the next starts:

export KEYSTROKE_HOOK=./hooks/front-matter.sh:./hooks/publish.sh

see docs/hooks.md for the full contract and a publish-to-blog example.

development

make format   # prettier
make test     # node --test
make build    # no-op, nothing to compile
make dev      # run the server
make demo     # run the server with the bundled word-count hook
