babel-loader presets

[kbetts]

I ran into an issue with the webpack build failing. It can be fixed by setting the "presets" option for babel-loader to react in the webpack.config.js file.

The issue is probably a nuance to my environment, although there is some background here and here. The preferred solution is to probably use a .babelrc config file as described here.

Original webpack.config.js file,

Adding a "preset" option for babel-loader in the module.rules array solves the issue (although see the link above regarding the .babelrc config file solution),

The code actually does have a .babelrc config file, as discussed in the book under Chapter 2: Preparing the Development Environment -> Checking your development setup -> Configuring Babel, Webpack, and Nodemon.

But I just saw that the .babelrc file is missing in the PacktPublishing/Full-Stack-React-Projects code repository. Thank you for pointing this out.

Thank you for following up so quickly. I had cloned the Packt repository. Build works perfectly after reverting the webpack.config.js file and added the .babelrc found here.
