bincr

Super simple incremental build helper. (inspired by bazel)

$ npx bincr init
# edit `.bincr.json`'s watch and cmd
# echo ".bincr-hash" >> .gitignore 
$ npx bincr # Run command with update .bincr-hash

# second run
$ npx bincr # Skip because of same hash

# after watch targets ...
$ npx bincr # Run command by target changes

# watch!
$ npx bincr -w

How it works

• Generate merkle hash for watched targets
• Compare .bincr-hash and current hash
• Run cmd if hash changed
• Update .bincr-hash

How to use: Exec

$ npx bincr # run default
$ npx bincr "npm run build" # run default
$ npx bincr -f # run force

How to use: Status Code

$ npx bincr changed && echo 1
# with hash update
$ npx bincr changed -u && echo 1

Config: .bincr.json

{
  "watch": ["src/**"], # hash targets
  "cmd": "npm run build"
}
