Dependencies

Recipe Dependencies

Run other recipes first using brackets:

task build:
    echo "Building..."

task test: [build]
    echo "Testing..."

task deploy: [build, test]
    echo "Deploying..."

Running jake deploy executes: build → test → deploy

File Dependencies

For file recipes, list source files/patterns after the colon:

file dist/bundle.js: src/index.ts src/utils.ts
    esbuild src/index.ts --bundle --outfile=dist/bundle.js

Glob Patterns

Use glob patterns for file dependencies:

file dist/app.js: src/**/*.ts
    esbuild src/index.ts --bundle --outfile=dist/app.js

Supported patterns:

• * - Match any characters except /
• ** - Match any characters including / (recursive)
• ? - Match single character
• [abc] - Match character class
• [a-z] - Match character range

Dependency Chains

File recipes automatically run recipes that produce their dependencies:

file dist/compiled.js: src/**/*.ts
    tsc --outFile dist/compiled.js

file dist/bundle.js: dist/compiled.js
    terser dist/compiled.js -o dist/bundle.js

task build: [dist/bundle.js]
    echo "Build complete!"

Running jake build automatically runs compilation first.

Mixed Dependencies

Combine recipe and file dependencies:

task setup:
    npm install

file dist/app.js: src/**/*.ts
    tsc --outDir dist

task build: [setup, dist/app.js]
    echo "Build complete!"

Avoiding Cycles

Jake detects cyclic dependencies:

# This will error!
task a: [b]
    echo "A"

task b: [a]
    echo "B"

error: Cyclic dependency detected in 'a'
