📦 Install

Installs all project dependencies according to composer.json, with the option to skip development dependencies or optimize the autoloader.

When to use

Use this after pulling project code, before deployment, or when composer.lock exists and dependencies need to be restored at the locked versions. Equivalent to running composer install [--no-dev] [--optimize-autoloader].

Signature

func (c *Composer) Install(noDev bool, optimize bool) error

Parameters

Parameter	Type	Description
noDev	bool	When true, does not install the development dependencies in require-dev
optimize	bool	When true, optimizes the autoloader by generating a class map, improving production performance

Return value

error: Returns the corresponding error message when an error occurs during installation; nil on success.

Example

package main

import (
	"fmt"
	"log"

	"github.com/scagogogo/composer-skills/pkg/composer"
)

func main() {
	comp, err := composer.New(composer.DefaultOptions())
	if err != nil {
		log.Fatalf("Initialization failed: %v", err)
	}

	// Development environment: install all dependencies (including dev dependencies)
	if err := comp.Install(false, false); err != nil {
		log.Fatalf("Install dependencies failed: %v", err)
	}

	// Production environment: install only production dependencies and optimize the autoloader
	if err := comp.Install(true, true); err != nil {
		log.Fatalf("Production install failed: %v", err)
	}

	fmt.Println("Dependencies installed")
}

Advanced

• To pass more options (such as --prefer-dist, --no-scripts), use InstallWithOptions.
• To only simulate an install without actually modifying files, use InstallDryRun.
• To force installing from source or distribution packages, see InstallWithPreferSource and InstallWithPreferDist.
• To skip script execution, see InstallNoScripts.
