spoon

library0.1.10jsnpmunverified

Spoon is a JavaScript transpiler that converts synchronous code into continuation-passing style (CPS) by identifying specified function calls and rewriting the surrounding code to use callbacks. It parses JavaScript using Esprima, constructs a High-Level Intermediate Representation (HIR) in the form of a Control Flow Graph (CFG), and then renders the transformed code back to JavaScript. Current stable version is 0.1.10, with no recent releases. It is primarily a proof-of-concept for transpilation techniques and is not actively maintained. Differentiators include low-level CFG manipulation and selective transpilation via declaration comments.

Install & Compatibility

Where this runs

No compatibility data collected yet for this library.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

spoon

✓ const spoon = require('spoon')

✗ import spoon from 'spoon'

Package does not support ESM. Only CommonJS require works.

spoon.construct

✓ const { construct } = require('spoon')

Use as named import from require. This method expects an Esprima AST.

spoon.render

✓ const { render } = require('spoon')

Renders a CFG object back to JavaScript code string.

Transpile code to use callbacks for specified function calls, with minimal configuration.

const spoon = require('spoon'); const code = `var x = 1; var y = hardMath(x) * 2; console.log(y);`; const transformed = spoon(code, ['hardMath']); console.log(transformed); // Output uses callbacks for hardMath calls.

Debug

Known issues

breakingspoon() expects an array of function names as second argument, but many users pass a string or options object first.

fix

Always pass an array: spoon(code, ['funcName'], options)

affects: >=0.0.0

deprecatedThe package is unmaintained since 2012. No security patches or updates.

fix

Consider using modern alternatives like Babel plugins or Sweet.js for code transformation.

affects: >=0.0.0

gotchaSpoon uses UglifyJS for code generation, which may produce different formatting. The 'uglify' option is passed directly to UglifyJS; incorrect options may cause errors.

fix

Limit uglify options to known UglifyJS options from version 1.x.

affects: >=0.0.0

Errors

Common errors & fixes

Cannot find module 'spoon'

Package not installed or not resolved in node_modules.

fix

Install with: npm install spoon

spoon is not a function

Incorrect import style (e.g., import default from ESM).

fix

Use: const spoon = require('spoon');

Cannot read property 'construct' of undefined

Using CommonJS but not requiring the module correctly.

fix

Ensure you are using: const spoon = require('spoon');
