Setting Yarn config defaults globally

February 26, 2021

Check existing config with yarn config list
If you run the command to list config with a --verbose flag, it tells you which files it looked into for config and which ones it loaded from yarn config list --verbose
The global config is save in ~/.yarnrc.yml (Yarn 2.0 onwards. previously it was called .yarnrc)
if you set a config flag in a dir where there is no .yarnrc.yml, it'll add the config to the global config file at ~/.yarnrc.yml

code

# yarn config set <key> <value> [-g|--global]

yarn config set init-license 'CC-BY-SA-4.0' -g
yarn config set init-version '0.0.1' -g

unlike setting npm defaults, the -g flag must come at the end of the command.
init-author-name, init-author-email, and init-author-url are not available

code

# yarn config list

yarn config v1.22.10
info yarn config
{
  'version-tag-prefix': 'v',
  'version-git-tag': true,
  'version-commit-hooks': true,
  'version-git-sign': false,
  'version-git-message': 'v%s',
  'init-version': '0.0.1',
  'init-license': 'CC-BY-SA-4.0',
  'save-prefix': '^',
  'bin-links': true,
  'ignore-scripts': false,
  'ignore-optional': false,
  registry: 'https://registry.yarnpkg.com',
  'strict-ssl': true,
  'user-agent': 'yarn/1.22.10 npm/? node/v14.16.0 darwin arm64',
}
info npm config
{}

Alternatively, you can set the config in ~/.yarnrc.yml

code

# ~/.yarnrc.yml (Yarn 2.0 berry)

initLicense: 'CC-BY-SA-4.0'
initVersion: '0.0.1'
