The keys are the names\npassed to addFile or addUrl etc, and the value is an object with some\ninfo about the data source.\n\n## chain.addFile(filename, type, [name=filename])\n\nFilename is the name of the file. Name is an arbitrary string to be\nused later if you desire. Type is either 'ini' or 'json', and will\ntry to guess intelligently if omitted.\n\nLoaded files can be saved later.\n\n## chain.addUrl(url, type, [name=url])\n\nSame as the filename thing, but with a url.\n\nCan't be saved later.\n\n## chain.addEnv(prefix, env, [name='env'])\n\nAdd all the keys from the env object that start with the prefix.\n\n## chain.addString(data, file, type, [name])\n\nParse the string and add it to the set. (Mainly used internally.)\n\n## chain.add(object, [name])\n\nAdd the object to the set.\n\n## chain.root {Object}\n\nThe root from which all the other config objects in the set descend\nprototypically.\n\nPut your defaults here.\n\n## chain.set(key, value, name)\n\nSet the key to the value on the named config object. If name is\nunset, then set it on the first config object in the set. (That is,\nthe one with the highest priority, which was added first.)\n\n## chain.get(key, [name])\n\nGet the key from the named config object explicitly, or from the\nresolved configs if not specified.\n\n## chain.save(name, type)\n\nWrite the named config object back to its origin.\n\nCurrently only supported for env and file config types.\n\nFor files, encode the data according to the type.\n\n## chain.on('save', function () {})\n\nWhen one or more files are saved, emits `save` event when they're all\nsaved.\n\n## chain.on('load', function (chain) {})\n\nWhen the config chain has loaded all the specified files and urls and\nsuch, the 'load' event fires.\n", "readmeFilename": "readme.markdown", "bugs": { "url": "https://github.com/dominictarr/config-chain/issues" }, "_id": "config-chain@1.1.8", "dist": { "shasum": "0943d0b7227213a20d4eaff4434f4a1c0a052cad", "tarball": "http://registry.npmjs.org/config-chain/-/config-chain-1.1.8.tgz" }, "_from": "config-chain@>=1.1.8 <1.2.0", "_npmVersion": "1.3.6", "_npmUser": { "name": "dominictarr", "email": "dominic.tarr@gmail.com" }, "maintainers": [ { "name": "dominictarr", "email": "dominic.tarr@gmail.com" }, { "name": "isaacs", "email": "i@izs.me" } ], "directories": {}, "_shasum": "0943d0b7227213a20d4eaff4434f4a1c0a052cad", "_resolved": "https://registry.npmjs.org/config-chain/-/config-chain-1.1.8.tgz" }
