plugins

array of FeDevServerPlugin - serving logic depends on the plugins you create

plugin has some common config:

• enable: true / false, Default: true - activation of the plugin
• cfg: object, Default: undefined - config of the plugin
• match: string / RegExp / function, Default: '/' - activation of the plugin according to the request
• macth: string - using pathname prefix to devide the activation of the plugin, for examples, '/api/v1/login' is active while '/api/v2/login' is inactive when match is '/api/v1'
• match: RegExp - using pathname to check with the regexp, for exampels, '/api/v1/login' is active while '/api/v2/login' is inactive when match is /v1/
• match: function - pathname / method / search / headers passed to function, write your custom logic to decide the activation
• throwNotFoundWhenUnreplied: boolean, Default: false - throw not found when this plugin's handler executed without response
• uuid: string, Default: random uuID string - a unique string for distinguish plugin
• operation: object - config of operation in plugin
• operation.enable: boolean - weather to enable operation methods in plugin
• operation.urlPrefix: string - the url prefix for accessing the API
