Zipson is a drop-in alternative to JSON.parse/stringify with added compression and streaming support.
Try the online demo
- Running the tests
As an npm module
npm install --save zipson
Or alternatively from
jsdelivr with a script tag as a UMD bundle
Stringify data to a zipson string
;const myData = 1 2 3 4 5;const stringified = ;
stringifyTo(data, writer, options?)
Stringify data to a specific zipson writer
;const writer = ;const myData = 1 2 3 4 5;;const stringified = writervalue;
Parse a zipson string
;const myStringifiedData = '.......';const parsed = ;
Incrementally parse a zipson string. Call the returned function once for each chunk of the string, calling it with null will signal end of string and returned the parsed result.
;const increment = ;;;;;const parsed = ;
Compression options can be provided to the stringify functions. Parse however does not take any options since it is not dependent on knowing with what options the string was compressed.
Set to true to tell zipson to detect timestamps within strings such as
'2018-01-01T00:00:00Z' in order to represent them more efficiently.
By default floating point precision is reduced to
10^-3, set this to true in order to retain full floating point precision.
Compression output is generalized to a writer class in order to support different output targets. Custom writers have to implement the following API.
- Efficient compression with a convenient API
- Zero configuration drop-in replacement for JSON.stringify and JSON.parse
- Zero dependencies
- Detection of recurring patterns in recursive structures
- Automatic reduction of floating point precision unless you actually need those fine 10^-xx decimals
- Optional detection and compression of UTC timestamps in strings
- Stream support with the companion lib zipson-stream
- Support for browser and node
