each environment is configured with a separate configuration file. Different environments execute different packaging commands, and different configuration files are introduced.

if (process.env.NODE_ENV = 'test') {
require (' test.config.js')
} else if (process.env.NODE_ENV = 'pro') {
require (' pro.config.js')
}

code split types the configuration into a separate js file, inevitably with some compiled code, but this is already the best solution to build on webpack .

or skip webpack, and just use script to introduce it. The only disadvantage is that the configuration is exposed to a global variable, and cannot use webpack closures
