babel@7 and jest configuration

Question

Maybe you may help me? I try to configure jest to use babel@7 So I have:

\"jest\": \"^23.4.1\",
\"@babel/core\": \"^7.0.0-beta.54\",
\"babel-7-jest\": \"^21.3.3\         


        

Answer 1

You can find a working example and tutorial over here.

These are all my Babel packages:

"@babel/core": "^7.1.2",
"@babel/node": "^7.0.0",
"@babel/preset-env": "^7.1.0",
"@babel/preset-react": "^7.0.0",
"@babel/register": "^7.0.0",
"babel-core": "^7.0.0-bridge.0",
"babel-jest": "^23.6.0",
"babel-loader": "^8.0.4"

And I had to install babel-core@^7.0.0-bridge.0 like it is mentioned on the Jest website.

My .babelrc:

{
  "presets": [
    "@babel/preset-env",
    "@babel/preset-react"
  ]
}

And my npm script: jest --config ./test/jest.config.json It didn't change for the Babel 7 upgrade.
