For example, to send129big objects as json to server. Pako detects input data type. You can130force output to be string with option `{ to: 'string' }`.131 132```javascript133var pako = require('pako');134 135var test = { my: 'super', puper: [456, 567], awesome: 'pako' };136 137var binaryString = pako.deflate(JSON.stringify(test), { to: 'string' });138 139//140// Here you can do base64 encode, make xhr requests and so on.141//142 143var restored = JSON.parse(pako.inflate(binaryString, { to: 'string' }));144```145 146 147Notes148-----149 150Pako does not contain some specific zlib functions:151 152- __deflate__ -  methods `deflateCopy`, `deflateBound`, `deflateParams`,153  `deflatePending`, `deflatePrime`, `deflateTune`.154- __inflate__ - methods `inflateCopy`, `inflateMark`,155  `inflatePrime`, `inflateGetDictionary`, `inflateSync`, `inflateSyncPoint`, `inflateUndermine`.156- High level inflate/deflate wrappers (classes) may not support some flush157  modes. Those should work: Z_NO_FLUSH, Z_FINISH, Z_SYNC_FLUSH.158 159 160pako for enterprise161-------------------162 163Available as part of the Tidelift Subscription164 165The maintainers of pako and thousands of other packages are working with Tidelift to deliver commercial support and maintenance for the open source dependencies you use to build your applications.
