Software project initialization requires repetitive configuration of build tools, linters, test frameworks, and dependency management systems. This process consumes developer time and introduces inconsistencies across projects. We present easy-setup, a command-line tool that automates project scaffolding through declarative configuration templates. The system reduces initial setup time by approximately 85% compared to manual configuration while maintaining reproducibility across development environments.
Modern software development involves substantial overhead before writing application code. Developers must configure package managers, establish directory structures, initialize version control, and integrate development tooling. Studies indicate that engineers spend 2-4 hours on initial project setup for typical applications [1]. This repetitive work creates opportunities for configuration drift and human error.
Existing solutions like Yeoman and create-react-app address specific ecosystems but lack flexibility for custom workflows. Package managers provide init commands that generate minimal boilerplate without addressing the full configuration surface. Organizations often maintain internal scripts, but these become maintenance burdens as tooling evolves. The need persists for a generalized approach to project initialization that balances automation with customization.
The easy-setup system operates in three phases: template resolution, dependency analysis, and file generation. Templates are defined in JSON or YAML format, specifying files, dependencies, and post-installation scripts. The tool maintains a registry of common project types including TypeScript libraries, Node.js services, and full-stack applications.
During execution, the system constructs a dependency graph to determine installation order. It evaluates conditional logic based on user responses to interactive prompts. File generation uses a template engine with variable substitution, allowing customization without forking template definitions. The tool integrates with npm, yarn, and pnpm package managers through a unified interface.
Templates specify hooks for custom scripts at initialization and post-installation stages. This extensibility permits integration with organizational requirements such as license generation, Git repository configuration, and CI/CD pipeline setup. The architecture separates template definitions from execution logic, enabling community-contributed templates through a plugin system.
npm install -g easy-setup
import { EasySetup } from 'easy-setup';
// Programmatic API usage
const setup = new EasySetup({
template: 'typescript-library',
projectName: 'my-project',
options: {
testFramework: 'jest',
linter: 'eslint',
formatter: 'prettier'
}
});
await setup.initialize();
// CLI equivalent:
// $ easy-setup init --template typescript-library --name my-project
// ? Test framework: jest
// ? Linter: eslint
// ? Formatter: prettierEvaluation across 50 project initializations demonstrates consistent time savings. Manual setup of a TypeScript project with testing and linting averaged 127 minutes. The easy-setup tool completed equivalent configuration in 18 minutes including user input time, representing an 86% reduction. Template execution shows deterministic behavior with identical output given equivalent input parameters.
User studies with 12 developers indicate reduced cognitive load during project initialization. Participants reported confidence in configuration completeness compared to manual setup where steps are frequently omitted. Template-based approaches improved consistency across team projects, with configuration variance dropping from 34% to 3% as measured by tooling configuration file diffs.
The system has generated 2,847 projects across 15 organizations as of this writing. Community contributions have expanded the template library to 23 official templates covering common use cases. Template execution time scales linearly with file count, maintaining sub-minute performance for projects under 100 files.
