How to use the createEnv function from yeoman-environment

yeoman-environment.createEnv is a function that creates a new Yeoman environment, which can be used to run Yeoman generators programmatically.

How does yeoman-environment.createEnv work?

yeoman-environment.createEnv is a function in the Yeoman environment module that creates a new Yeoman environment instance. This environment instance can be used to run Yeoman generators programmatically. When you call yeoman-environment.createEnv, it returns a new instance of the Environment class. The Environment class is responsible for discovering and running Yeoman generators. The Environment instance has several methods that can be used to interact with Yeoman generators. For example, you can use the register method to register a generator with the environment, or you can use the create method to create a new instance of a registered generator. The Environment instance also has a run method, which can be used to run a registered generator. The run method takes the name of the generator and an options object as arguments. The options object can include parameters for the generator, such as the destination directory or the name of the generated file. Overall, yeoman-environment.createEnv is a useful function for creating a Yeoman environment instance, which can be used to run Yeoman generators programmatically. This is particularly useful for build systems and automated tools that need to generate code based on user input or configuration files.

const env = require("yeoman-environment").createEnv();

env.registerStub(generatorName, "./generators/stub");

env.run(generatorName, { option1: "value1", option2: "value2" }, (err) => {
  if (err) {
    console.log("Error:", err.message);
  } else {
    console.log("Generator completed successfully");
  }
});

In this example, we use yeoman-environment.createEnv to create a new instance of the Environment class. We then register a Yeoman generator with the environment using the registerStub method, which takes the name of the generator and the path to the generator's stub file. We then run the generator using the run method, passing in the name of the generator and an options object. The options object includes parameters for the generator, such as option1 and option2. We also include a callback function to handle any errors that may occur during the generator run. Overall, this example demonstrates how developers can use yeoman-environment.createEnv to create a Yeoman environment instance and run a generator programmatically.
