craft-js aids in creating JavaScript source code programmatically.
Install
yarn add @brigand/craft-js
# or
npm install --save @brigand/craft-js
fromValue
Currently the only API available, fromValue allows you to convert a primitive
JS value to either a babel AST node, or JS source code.
const { fromValue } = require('@brigand/craft-js');
const jsCode = fromValue({ x: 1, y: [2, 3] }).toJs();
console.log(jsCode);This program produces the following output:
{
x: 1,
y: [2, 3]
}
To get at the inner value (a babel AST node in this case) you can call
.unwrap().
const node = fromValue({ x: 1, y: [2, 3] }).unwrap();
node; /* =>
