@babel/plugin-codemod-object-assign-to-object-spread

Transforms old code that uses Object.assign with an Object Literal as the first param to use Object Spread syntax.

Examples

const obj = Object.assign({
  test1: 1,
}, other, {
  test2: 2,
}, other2);

Is transformed to:

const obj = {
  test1: 1,
  ...other,
  test2: 2,
  ...other2,
};
