7777e06a added a dependancy on playwright which wouldn't run in
nix-shell without extra configuration.
the simpliest configuration (used in this commit) required a more
recent version of nixpkgs unstable. unfortunately these more recent
versions introduce a 'system limit for file watchers reached' bug in
storybook's server when run on linux. This can be mitigated by
manually increasing the watcher limit.
attempts to fix the playwright nixpkgs dependancies to different
versions still introduced the bug
hopefully the bug will disapear in newer releases of nixpkgs unstable
add image and dom snapshot comparison for storybook components
image snapshot comparison can been flaky and produce many
false-positives. a higher threshold has been used to mitigate this
although it may not identify all regressions. DOM snapshots
supplement images to increase the likelihood of capturing
regressions.
consideration was given to using a shared library built in rust
for this and the cli utility but this was discounted for these
reasons:
1. different data storage and caching requirements
2. ndk is more mature and has extra features for building web
apps
3. use of shared svelte components in ndk
4. prospect of contributing git specific components to ndk to
encourage adoption among other clientus
start with a nix boilerplate for svelte that supports reproducible
builds
