JSON support is in all browsers we could conceivably care about; it's
ES5 and has perfect support in IE 8. No need to ship a library as
a core package, and no need to specify dependencies on it.
We could conceivably publish a new version of the `json` package that
is empty, so that apps using packages that still say `use("json")`
also get the code size reduction, but we'll wait until someone requests
that.
ejson
EJSON is an extension of JSON to support more types. It supports all JSON-safe types, as well as:
- Date - JavaScript
Date - Binary - JavaScript
Uint8Arrayor the result ofEJSON.newBinary - User-defined types - see
EJSON.addType
All EJSON serializations are also valid JSON. For example an object with a date and a binary buffer would be serialized in EJSON as:
{
"d": {"$date": 1358205756553},
"b": {"$binary": "c3VyZS4="}
}
For more details, see the EJSON section of the Meteor docs.
