library1.9.0jsnpmunverified

Run-time compiler for Electrum-enabled React components, based on babel-standalone. Version 1.9.0 is the latest stable release; the package has had a low release cadence with infrequent updates. It provides a Compiler class capable of transforming JavaScript to ES5 and building React components from source code at runtime. Key differentiators include integration with the Electrum framework, support for registering external symbols, and a built-in eval for ES6/JSX. Note that it compiles synchronously in the browser and depends on Electrum v4.3.0 as a peer dependency.

Verified usage

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

Compiler
✓ import { Compiler } from 'electrum-compiler'
✗ import Compiler from 'electrum-compiler'
Compiler is a named export, not default.
Compiler
✓ const { Compiler } = require('electrum-compiler')
✗ const Compiler = require('electrum-compiler')
CommonJS destructuring required for named export.
Compiler
✓ import { Compiler } from 'electrum-compiler'
✗ import { compile } from 'electrum-compiler'
No function named compile; use Compiler class.

Demonstrates transforming ES6 to ES5, building an Electrum-enabled React component with registered symbols, and evaluating expressions.

import { Compiler } from 'electrum-compiler'; const compiler = new Compiler(); // Transform ES6 to ES5 const es5Source = compiler.transform('const greet = x => `Hello ${x}.`;'); console.log(es5Source); // Build a React component with Electrum support const componentSource = ` class extends React.Component { render() { return <Button>{text}</Button>; } }`; compiler.register('Button', Button); // Assume Button is a React component compiler.register('text', 'Hello'); const output = compiler.build('MyComponent', componentSource); if (output.error) { console.error(output.error); } else { console.log('Component:', output.component); } // Evaluate an expression const result = compiler.eval('2 + 3'); console.log(result); // 5

Known issues
gotchaError positions in build() are offset by one line due to prepended code.
fix
When interpreting error line numbers, subtract 1 from the reported line.
affects: >=1.0.0
gotchaThe compiler relies on a bundled babel-standalone; large bundle size may impact browser performance.
fix
Consider lazy-loading the compiler or using a server-side compilation approach for production.
affects: >=1.0.0
gotchaThe register() method stores items in a global-like catalog; multiple components may conflict if keys overlap.
fix
Use unique keys when registering symbols, or create separate Compiler instances for isolation.
affects: >=1.0.0
Errors
