\n \n debug | \n Show more verbose logging? | \n false | \n
\n \n dest | \n Destination directory to output the compiled .css files. | \n Same directory as less source files. | \n
\n \n force | \n Always re-compile less files on each request. | \n false | \n
\n \n once | \n Only recompile once after each server restart. Useful for reducing disk i/o on production. | \n false | \n
\n \n pathRoot | \n Common root of the source and destination. It is prepended to both the source and destination before being used. | \n null | \n
\n \n postprocess | \n Object containing functions relevant to postprocessing data. | \n | \n
\n \n postprocess.css | \n Function that modifies the compiled css output before being stored. | \n function(css, req){...} | \n
\n \n preprocess | \n Object containing functions relevant to preprocessing data. | \n | \n
\n \n preprocess.less | \n Function that modifies the raw less output before being parsed and compiled. | \n function(src, req){...} | \n
\n \n preprocess.path | \n Function that modifies the less pathname before being loaded from the filesystem. | \n function(pathname, req){...} | \n
\n \n preprocess.importPaths | \n Function that modifies the import paths used by the less parser per request. | \n function(paths, req){...} | \n
\n \n render | \n Options for the less render. See the \"render Options\" section below. | \n … | \n
\n \n storeCss | \n Function that is in charge of storing the css in the filesystem. | \n function(pathname, css, req, next){...} | \n
\n \n cacheFile | \n Path to a JSON file that will be used to cache less data across server restarts. This can greatly speed up initial load time after a server restart - if the less files haven't changed and the css files still exist, specifying this option will mean that the less files don't need to be recompiled after a server restart. | \n | \n
