Readme
A simple steganography library for adding hidden JSON data to strings.
This package exports a few methods for encoding and decoding data. All of these methods have TypeScript type definitions and JSDoc comments explaining their parameters and return values.
vercelStegaCombine(string, json, skip = 'auto')
This method combines a string
with some JSON data and returns the result. The json
can be any value that can be JSON stringified.
When the skip
property is true
, the original string will be returned without combining the json
. It supports boolean
values and 'auto'
. The default is 'auto'
, which will only skip encoding when the string
is an ISO date string or a URL.
vercelStegaCombine('Hello world', { foo: 'bar' });
// -> 'Hello world' (the JSON data is hidden in the new string)
vercelStegaEncode(json)
This method encodes JSON data as a hidden string and returns the result. The json
can be any value that can be JSON stringified.
vercelStegaEncode({ foo: 'bar' });
// -> '' (the JSON data is hidden)
vercelStegaSplit(string)
This method splits out the original string (cleaned) and the encoded portion of the string.
// In 'Hello world' (the extra data is hidden)
vercelStegaSplit('Hello world');
/*
* -> {
* cleaned: 'Hello world', // This doesn't contain the encoded data
* encoded: '', // This is not an empty string, it contains the encoded data
* }
*/
vercelStegaClean(json)
This method strips all encoded stega data from the value and returns the cleaned value. It accepts any JSON value.
// In 'Hello world' (the extra data is hidden)
vercelStegaClean('Hello world');
/*
* -> 'Hello world' // This doesn't contain the encoded data
*/
// In 'Hello world' (the extra data is hidden)
vercelStegaClean({
nested: {
value: 'Hello world',
},
});
/*
* -> { nested: { value: 'Hello world' } } // This doesn't contain the encoded data
*/
vercelStegaDecode(string)
This method attempts to extract encoded JSON data from a string
.
// In 'Hello world' (the extra data is hidden)
vercelStegaDecode('Hello world');
// -> { foo: 'bar' }
