What is @umijs/utils?

@umijs/utils is a utility library that provides a collection of helper functions and utilities for common tasks in JavaScript and TypeScript projects. It is particularly useful for developers working with UmiJS, a popular React framework, but can be used independently as well.

What are @umijs/utils's main functionalities?

File System Utilities

Provides utilities for reading and writing files, making it easier to handle file operations.

const { readFileSync, writeFileSync } = require('@umijs/utils');
const data = readFileSync('example.txt', 'utf-8');
writeFileSync('example_copy.txt', data);

Path Utilities

Includes functions for handling and manipulating file paths, which is useful for resolving paths in a cross-platform manner.

const { join, resolve } = require('@umijs/utils');
const fullPath = join(__dirname, 'src', 'index.js');
const absolutePath = resolve('src', 'index.js');

Environment Utilities

Provides utilities to check the current environment, which is useful for conditional logic based on the environment.

const { isDev, isProd } = require('@umijs/utils');
if (isDev()) {
  console.log('Running in development mode');
} else if (isProd()) {
  console.log('Running in production mode');
}

Logging Utilities

Includes logging utilities with color support via chalk, making it easier to format and display log messages.

const { chalk, logger } = require('@umijs/utils');
logger.info(chalk.green('This is an info message'));
logger.error(chalk.red('This is an error message'));
