Work with raw binary data

Data represents raw binary data and provides conversion methods.

Use Data to:

Examples ​

javascript
let data = Data.fromString("Hello World");
console.log(data.toRawString());
javascript
let data = Data.fromString("Hello");
let base64 = data.toBase64String();
let decoded = Data.fromBase64String(base64);
javascript
let imageData = Data.fromPNG(image);
let bytes = imageData.getBytes();

Methods ​

toRawString ​

Convert data to UTF-8 string

typescript
toRawString(): string | null

toBase64String(): string

Returns: Base64 encoded string

Example:

javascript
data.toBase64String()

getBytes ​
