The 'root' event passes the root object & the count of matched objects.\n\nif `path` is empty or null, no 'data' events are emitted.\n\n### example\n\nquery a couchdb view:\n\n``` bash\ncurl -sS localhost:5984/tests/_all_docs&include_docs=true\n```\nyou will get something like this:\n\n``` js\n{\"total_rows\":129,\"offset\":0,\"rows\":[\n { \"id\":\"change1_0.6995461115147918\"\n , \"key\":\"change1_0.6995461115147918\"\n , \"value\":{\"rev\":\"1-e240bae28c7bb3667f02760f6398d508\"}\n , \"doc\":{\n \"_id\": \"change1_0.6995461115147918\"\n , \"_rev\": \"1-e240bae28c7bb3667f02760f6398d508\",\"hello\":1}\n },\n { \"id\":\"change2_0.6995461115147918\"\n , \"key\":\"change2_0.6995461115147918\"\n , \"value\":{\"rev\":\"1-13677d36b98c0c075145bb8975105153\"}\n , \"doc\":{\n \"_id\":\"change2_0.6995461115147918\"\n , \"_rev\":\"1-13677d36b98c0c075145bb8975105153\"\n , \"hello\":2\n }\n },\n]}\n\n```\n\nwe are probably most interested in the `rows.*.docs`\n\ncreate a `Stream` that parses the documents from the feed like this:\n\n``` js\nvar stream = JSONStream.parse(['rows', true, 'doc']) //rows, ANYTHING, doc\n\nstream.on('data', function(data) {\n console.log('received:', data);\n});\n\nstream.on('root', function(root, count) {\n if (!count) {\n console.log('no matches found:', root);\n }\n});\n```\nawesome!\n\n## JSONStream.stringify(open, sep, close)\n\nCreate a writable stream.\n\nyou may pass in custom `open`, `close`, and `seperator` strings.\nBut, by default, `JSONStream.stringify()` will create an array,\n(with default options `open='[\\n', sep='\\n,\\n', close='\\n]\\n'`)\n\nIf you call `JSONStream.stringify(false)`\nthe elements will only be seperated by a newline.\n\nIf you only write one item this will be valid JSON.\n\nIf you write many items,\nyou can use a `RegExp` to split it into valid chunks.\n\n## JSONStream.stringifyObject(open, sep, close)\n\nVery much like `JSONStream.stringify`,\nbut creates a writable stream for objects instead of arrays.\n\nAccordingly, `open='{\\n', sep='\\n,\\n', close='\\n}\\n'`.\n\nWhen you `.write()` to the stream you must supply an array with `[ key, data ]`\nas the first argument.\n\n## numbers\n\nThere are occasional problems parsing and unparsing very precise numbers.\n\nI have opened an issue here:\n\nhttps://github.com/creationix/jsonparse/issues/2\n\n+1\n\n## Acknowlegements\n\nthis module depends on https://github.com/creationix/jsonparse\nby Tim Caswell\nand also thanks to Florent Jaby for teaching me about parsing with:\nhttps://github.com/Floby/node-json-streams\n\n## license\n\nMIT / APACHE2\n", "readmeFilename": "readme.markdown", "bugs": { "url": "https://github.com/dominictarr/JSONStream/issues" }, "_id": "JSONStream@0.4.4", "_from": "JSONStream@~0.4.3" }
