  • 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
1# yarn config set <key> <value> [-g|--global]
2
3yarn config set init-license 'CC-BY-SA-4.0' -g
4yarn 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
