How it works

1. Look for package.json for bic config (example config - "bic": ["src"]).

2. Crawl the folders that are defined in config and generates a combined SHA-1 hash of all the files in defined folders. The hashes are stored in ./node_modules/bic-build-if-changed/cache.

3. If the stored hash of the project folders is outdated, then bic will execute npm run build in the relevant project folder.

Usage

1. Install the package:

npm i bic-build-if-changed -D
# or
yarn add bic-build-if-changed -D

2. Edit your package.json module to customize the behavior:

// Only the "src" & "public" directories:
"bic": ["src", "public"],
// Disable bic for a package:
"bic": false,
// Use default directories ("src"):
"bic": true,

3. Use the package: (using with npm)

npm run build-if-changed
# or
npm run bic
# you can use -force (or) -F flag to Force Re-Build
npm run bic -F

3. Use the package: (using with yarn)

yarn build-if-changed
# or
yarn bic
# you can use -force (or) -F flag to Force Re-Build
yarn bic -F

Notes

• Only bic config directories are watched, by default ./src directory is only watched.
