How are you using Babel?

Programmatic API (babel.transform, babel.parse)

Input code

const {ast} = require('@babel/eslint-parser').parseForESLint('export { "a" } from "a";', {requireConfigFile: false})

ast.body[0].specifiers[0]
Node {
  type: 'ExportSpecifier',
  start: 9,
  end: 12,
  loc: SourceLocation {
    start: Position { line: 1, column: 9 },
    end: Position { line: 1, column: 12 },
    filename: undefined,
    identifierName: undefined
  },
  range: [ 9, 12 ],
  local: Node {
    type: 'Literal',
    start: 9,
    end: 12,
    loc: SourceLocation {
      start: [Position],
      end: [Position],
      filename: undefined,
      identifierName: undefined
    },
    range: [ 9, 12 ],
    value: 'a',
    raw: '"a"'
  },
  exported: Node {
    type: 'StringLiteral',    // <------------ Here
    start: 9,
    end: 12,
    loc: SourceLocation {
      start: [Position],
      end: [Position],
      filename: undefined,
      identifierName: undefined
    },
    range: [ 9, 12 ],
    extra: undefined,
    value: 'a'
  }
}

Additional context

Similar to #13329, but only happens when specifier is shorthand.

This is a regression introduced in #13611.

The cloneStringLiteral method always set type to StringLiteral:

babel/packages/babel-parser/src/parser/node.js

Line 82 in 94af0e5

cloned.type = "StringLiteral";

we can override cloneStringLiteral in estree plugin.
