The readable.readableEncodin property in a readable Stream is utilized to get the property encoding of a stated readable stream. Moreover, you can set this property using readable.setEncoding() method.
Syntax:
readable.readableEncoding
Return Value: It returns the encoding used in the program.
Below examples illustrate the use of readable.readableEncoding property in Node.js:
Example 1:
// Node.js program to demonstrate the // readable.readableEncoding Property // Include fs module const fs = require( "fs" );
// Constructing readable stream const readable = fs.createReadStream( "input.text" );
// Setting the encoding readable.setEncoding( "base64" );
// Instructions for reading data readable.on( 'readable' , () => {
let chunk;
// Using while loop and calling
// read method with parameter
while ( null !== (chunk = readable.read())) {
// Displaying the chunk
console.log(`read: ${chunk}`);
}
}); // Calling readableEncoding property readable.readableEncoding; |
Output:
read: aGVs read: bG8=
Example 2:
// Node.js program to demonstrate the // readable.readableEncoding Property // Include fs module const fs = require( "fs" );
// Constructing readable stream const readable = fs.createReadStream( "input.text" );
// Setting the encoding readable.setEncoding( "hex" );
// Instructions for reading data readable.on( 'readable' , () => {
let chunk;
// Using while loop and calling
// read method with parameter
while ( null !== (chunk = readable.read())) {
// Displaying the chunk
console.log(`read: ${chunk}`);
}
}); // Calling readableEncoding property readable.readableEncoding; |
Output:
read: 68656c6c6f
