Installation

npm install esbuild-plugin-scriptable --save-dev

pnpm add esbuild-plugin-scriptable --save-dev

yarn add esbuild-plugin-scriptable --dev

Basic Usage

import {build} from 'esbuild';
import {scriptableBanner, scriptableDeploy} from 'esbuild-plugin-scriptable';

await build({
  entryPoints: ['src/widget.ts'],
  outfile: 'dist/widget.js',
  bundle: true,
  plugins: [
    scriptableBanner({
      warnOnMissingManifest: true,
      patterns: '**/*.widget.ts',
    }),
    scriptableDeploy({
      logLevel: 'verbose',
      patterns: '**/*.widget.ts',
    }),
  ],
});

Configuration

Banner Plugin Options

• manifestExtensions: Custom manifest file extensions (default: '.manifest.json', '.manifest', '.json')
• warnOnMissingManifest: Show warning when manifest file is missing (default: true)
• warnOnInvalidManifest: Show warning when manifest file is invalid (default: true)
• warnOnMissingEntry: Show warning when no matching entry point is found (default: true)
• getManifestPath: Custom manifest file path mapping function
• patterns: Source file patterns to match entry points (default: '*/.{ts,tsx,js,jsx}')
  • Can be a string or array of strings
  • Supports glob patterns with negation (! prefix)
  • Examples:
    • '**/*.widget.ts' - only process widget source files
    • ['**/*.ts', '!**/*.test.ts'] - exclude test files
• logLevel: Control logging detail (default: 'auto')
  • 'auto': Use esbuild's logLevel
  • 'silent': No logs
  • 'error': Only errors
  • 'warn': Errors and warnings
  • 'info': Normal output
  • 'verbose': Detailed output

Deploy Plugin Options

• logLevel: Control deployment logging detail (default: 'normal')
  • 'silent': No logs
  • 'normal': Basic deployment info
  • 'verbose': Detailed deployment info
  • 'debug': All deployment details
• continueOnError: Continue building when deployment fails (default: true)
• scriptableDir: Custom Scriptable directory path (default: auto-detect in iCloud Drive)
• patterns: Source file patterns to match entry points (default: '*/.{ts,tsx,js,jsx}')
  • Can be a string or array of strings
  • Supports glob patterns with negation (! prefix)
  • Examples:
    • '**/*.widget.ts' - only deploy widget source files
    • ['**/*.ts', '!**/*.test.ts'] - exclude test files
• addBanner: Whether to add Scriptable banner from manifest (default: true)
• manifestExtensions: Custom manifest file extensions (default: '.manifest.json', '.manifest', '.json')

Manifest Configuration

The manifest file can be used to configure both the script metadata and the output filename:

{
  "name": "weather-widget",
  "alwaysRunInApp": true,
  "shareSheetInputs": ["file-url", "url"],
  "iconColor": "blue",
  "iconGlyph": "cloud",
  "version": "1.0.0",
  "description": "A weather widget for Scriptable"
}

When a manifest includes a name property:

• The deploy plugin will use this name for the output file (e.g., weather-widget.js)
• If no name is specified, the original filename will be used
• The banner plugin will still use all manifest properties to generate the script metadata

Advanced Usage

import {build} from 'esbuild';
import {scriptableBanner, scriptableDeploy} from 'esbuild-plugin-scriptable';

await build({
  entryPoints: ['src/widget.ts'],
  outfile: 'dist/widget.js',
  bundle: true,
  plugins: [
    scriptableBanner({
      warnOnMissingManifest: true,
      patterns: ['**/*.ts', '!**/*.test.ts'],
      getManifestPath: entryPath => {
        return entryPath.replace(/\.ts$/, '.manifest.json');
      },
    }),
    scriptableDeploy({
      logLevel: 'verbose',
      addBanner: true,
      patterns: ['**/*.ts', '!**/*.test.ts'],
      scriptableDir: '/custom/path/to/Scriptable',
    }),
  ],
});

Banner Behavior

The banner can be added in two stages:

1. Build stage (via scriptableBanner plugin):

   • Adds banner to the build output files
   • Banner is part of the compiled result

2. Deploy stage (via scriptableDeploy plugin's addBanner option):

   • Does not affect build output files
   • Only adds banner to the deployed files in Scriptable directory
   • Will update/override any existing banner in the target file

When using both plugins:

• scriptableBanner will add banner to build output
• scriptableDeploy with addBanner: true will update/override the banner in deployed files
• scriptableDeploy with addBanner: false will keep the existing banner (if any)

// Example 1: Banner in both build output and deployed files
plugins: [
  scriptableBanner({...}),  // Adds banner to build output
  scriptableDeploy({
    addBanner: true   // Updates banner in deployed files
  })
]

// Example 2: Banner only in deployed files
plugins: [
  scriptableDeploy({
    addBanner: true   // Adds banner only to deployed files
  })
]

// Example 3: Banner only in build output
plugins: [
  scriptableBanner({...}),  // Adds banner to build output
  scriptableDeploy({
    addBanner: false  // Keeps existing banner in deployed files
  })
]

The addBanner option in scriptableDeploy:

• Only affects the files in Scriptable directory
• Does not modify the build output files
• When true, will ensure the latest banner from manifest is used in deployed files
• When false, will preserve any existing banner in the files
