TextEncoder - Web APIs | MDN (original) (raw)
Baseline
Widely available
Note: This feature is available in Web Workers.
The TextEncoder interface takes a stream of code points as input and emits a stream of UTF-8 bytes.
Constructor
Returns a newly constructed TextEncoder that will generate a byte stream with UTF-8 encoding.
Instance properties
The TextEncoder interface doesn't inherit any properties.
TextEncoder.encoding Read only
Always returns utf-8.
Instance methods
The TextEncoder interface doesn't inherit any methods.
Takes a string as input, and returns a Uint8Array containing UTF-8 encoded text.
Takes a string to encode and a destination Uint8Array to put resulting UTF-8 encoded text into, and returns an object indicating the progress of the encoding. This is potentially more performant than the older encode() method.
Examples
const encoder = new TextEncoder();
const view = encoder.encode("€");
console.log(view); // Uint8Array(3) [226, 130, 172]
