⚡ Update

Updates the project's dependencies to the latest versions allowed by the composer.json constraints. You can specify particular packages or update all dependencies.

When to use

Use this when you want to obtain new dependency versions, fix bugs, or upgrade packages. Note that update rewrites composer.lock, unlike install which restores from the lock. Equivalent to running composer update [--no-dev] [packages...].

Signature

func (c *Composer) Update(packages []string, noDev bool) error

Parameters

Parameter	Type	Description
packages	[]string	List of package names to update; pass an empty slice []string{} to update all packages
noDev	bool	When true, development dependencies are not updated

Return value

error: returns the corresponding error message when an error occurs during the update; 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("init failed: %v", err)
	}

	// Update all dependencies (including development dependencies)
	if err := comp.Update([]string{}, false); err != nil {
		log.Fatalf("update dependencies failed: %v", err)
	}

	// Update only the specified packages
	if err := comp.Update([]string{"symfony/console", "symfony/process"}, false); err != nil {
		log.Fatalf("update specified packages failed: %v", err)
	}

	fmt.Println("dependencies update complete")
}

Advanced

• When you need to pass options such as --prefer-dist or --with-dependencies, use UpdateWithOptions.
• When you only want to simulate the update and preview the changes, use UpdateDryRun.
• To update dependency packages as well, see UpdateWithDependencies.
• To only refresh the lock hash without upgrading package versions, see UpdateWithLock.
