如果 package.json 文件中的版本未更改/升级，如何限制构建反应项目

Question

I want to enable production-level restriction in building to react application. I want that if I do not change the version of react application it should give me an error during the build process with the error message "Change the react version in Package.json file". How do I accomplish this strategy

Answer 1

Call the global process object's exit method

Node.js will normally exit with a 0 status code when no more async operations are pending. The following status codes are used in other cases:

1 Uncaught Fatal Exception: There was an uncaught exception, and it was not handled by a domain or an 'uncaughtException' event handler.

For more information about exit codes you can take a look at process_exit_codes

Note: I did not tried to stop a build but you can try the following:

 const REACT_VERSION = React.version; console.log(REACT_VERSION) if(REACT_VERSION <= "16.6.3"){ console.log("Change the react version in Package.json file, the current version is smaller than the lastes available.") process;exit(1); }
