Parameters: This method accepts three parameters as mentioned above and described below:
- buffer: It can be of type Buffer, TypedArray, DataView, ArrayBuffer, and string.
- options: It is an optional parameter that holds the zlib options.
- callback: It holds the callback function.
Return Value: It returns the chunk of data after decompression.
Below examples illustrate the use of
zlib.brotliDecompress() method in Node.js:
Example 1:
Output:
