yarn config set

This command will set a configuration setting, by default in the project configuration file unless the -H,--home flag is set, in which case it will be set in the home configuration file.

When used without the --json flag, the new value will be hydrated depending on the type of the field being set: primitives such as strings will be hydrated directly, while complex types such as arrays and objects will be hydrated through JSON.

When used with the --json flag, the new value will always be parsed as JSON before being written to the configuration file.

Options
