💾 SaveAuthConfig

Writes the given authentication configuration to the auth.json file in the Composer home directory in JSON format.

When to use

Use this when you directly construct or modify an AuthConfig struct (rather than going through the Add*Token family of convenience methods) and need to persist the change to disk. It can also be used for batch import/migration of authentication configuration.

Signature

func (c *Composer) SaveAuthConfig(config *AuthConfig) error

Parameters

Parameter	Type	Description
config	*AuthConfig	Pointer to the authentication configuration struct to save

Return value

error: returns the corresponding error message when getting the directory, creating the directory, or writing the file fails; 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)
	}

	// Directly construct and save an authentication configuration
	config := &composer.AuthConfig{
		GitHub: map[string]string{
			"github.com": "ghp_xxxxxxxxxxxxxxxxxxxx",
		},
		HTTPBasic: map[string]string{
			"repo.intranet.com": "ci-user:s3cret",
		},
	}

	if err := comp.SaveAuthConfig(config); err != nil {
		log.Fatalf("save auth config failed: %v", err)
	}

	fmt.Println("auth.json written")
}

Advanced

• The file is serialized with json.MarshalIndent (4-space indentation), with permission 0600, readable and writable only by the current user.
• Before writing, os.MkdirAll ensures the Composer home directory exists.
• You usually do not need to call this manually; the Add*Token family of methods already call it internally. See GetAuthConfig.
