Usage:

yarn add jest-serializer-simple

Then add it to your Jest config:

module.exports = {
  testEnvironment: "node",
  snapshotSerializers: [`jest-serializer-simple`],
  //...
};

To tell Jest that you want the object to be printed simply, you must wrap it in an object with just the __ key: { __: YOUR_VALUE_HERE }, for example:

expect({ __: data }).toMatchInlineSnapshot(`
  {
    forums: [
      {
        name: 'Cats',
      },
      {
        name: 'Dogs',
      },
      {
        name: 'Postgres',
      },
    ],
  }
`);
