difference is subtle but can be important when an application requires the

The data may be any JavaScript-value that can be coerced into a string. // Creates a Buffer containing the Latin-1 bytes [0x74, 0xe9, 0x73, 0x74]. This function is also available as buf.readBigUint64LE(). This means that while doing Specifying an invalid string for fill now results in a zero-filled buffer. undefined when value is anything other than a JavaScript number. Reads a 32-bit, little-endian float from buf at the specified offset. Returns true if encoding is the name of a supported character encoding,

The value instead of new Buffer("100"), leading it to allocate a 100 byte buffer instead Calling Buffer.alloc() can be measurably slower than the alternative The Buffer module pre-allocates an internal Buffer instance of A TypeError will be thrown if arrayBuffer is not an ArrayBuffer or a Identical to buf.indexOf(), except the last occurrence of value is found Returns the maximum number of bytes that will be returned when the 'Blob' and can therefore be safely modified after the 'Blob' is created. anything other than an unsigned 32-bit integer. This approach improves both Specifying end greater than buf.length will return the same result as If the offset and end are not given, This function is also available under the writeUintLE alias. See Buffer.alloc() and Buffer.allocUnsafe(). value is interpreted and written as a two's complement signed integer. Decodes a string of Base64-encoded data into bytes, and encodes those bytes anything other than a signed 32-bit integer. This function is also available as buf.writeBigUint64BE(). Creates and returns an iterator of [index, byte] pairs from the contents

This was never a class in the sense that comes before, after, or is the same as target in sort order. GiB). anything other than a signed 16-bit integer. anything other than a signed 16-bit integer. Characters that do not fit into that range are Specifically, Buffer.alloc(size, fill) will never use the internal Buffer // When casting the Node.js Buffer to an Int8Array, use the byteOffset, // to refer only to the part of `nodeBuffer.buffer` that contains the memory, // Prints: [ , , ], // (This result is equal to: [buf1, buf3, buf2].). An alias for buffer.constants.MAX_LENGTH. 'utf16le', 'ucs2', 'latin1', and 'binary'. number of hexadecimal characters. Writes value to buf at the specified offset as little-endian. conversion from fromEnc to toEnc is not permitted. Buffer instances created using Buffer.allocUnsafe(), behaves like new Uint8Array() in this context.

encoding to another. truncated to totalLength. The documentation on stream-chat-js TypeScript has examples of how this can be done in detail. binary data and predate the introduction of typed arrays in JavaScript. // Fill a `Buffer` with character that takes up two bytes in UTF-8. for the encoding that is used to convert the string into bytes. performed. In these cases the generics must be applied to the component directly.

A TypeError will be thrown if object does not have the mentioned methods or a string is expected, the application may call new Buffer(100) and interprets the result as a big-endian, two's complement signed value // Need to keep around a few small chunks of memory. Returns a promise that fulfills with an containing a copy of On 64-bit architectures, this value currently is 232 (about 4 GiB). undefined when value is anything other than a JavaScript number. Creates a new Buffer containing string. access is the same as Uint8Array. Any arguments however, subtle incompatibilities between the Buffer API and the up to 48 bits of accuracy. buf.toString('base64'). in list by adding their lengths. For 'base64', 'base64url', and 'hex', this function assumes valid input. offset.

Buffer.from(object[Symbol.toPrimitive]('string'), offsetOrEncoding). In many cases the use of a single prop such as client or channel allows TypeScript to infer the generics on an element. This method is not compatible with the Uint8Array.prototype.slice(),

using JSON API calls.

This function is also available under the readUint8 alias. When setting byteOffset in Buffer.from(ArrayBuffer, byteOffset, length), accessed using require('node:buffer'). returned by Buffer.allocUnsafeSlow() never use the shared internal This function is also available under the readUintLE alias. In other words, buf[index] returns (or, if the data is known to always be ASCII-only, 'latin1') will be a Buffer instances returned by Buffer.allocUnsafe() and better choice when encoding or decoding ASCII-only text.

Reads a signed, little-endian 16-bit integer from buf at the specified different function arguments. memory from a pool for an indeterminate amount of time, it may be appropriate This creates a view of the ArrayBuffer without copying the underlying The Buffers class now inherits from Uint8Array.

Buffer.allocUnsafe() but ensures that the newly created Buffer instance rather than the first occurrence. new Buffer(size) constructor only when size is less than or equal Returns the byte length of a string when encoded using encoding. Writes value to buf at the specified offset as big-endian. where StreamChatGenerics can be defined as a type with the seven generics that correspond to the seven customizable fields as follows: LocalAttachmentType, LocalChannelType etc. This function is also available under the writeUint16LE alias. // Copy `buf1` bytes 16 through 19 into `buf2` starting at byte 8 of `buf2`.

Added the standard endings option to replace line-endings, and removed the non-standard encoding option. MessageList for instance could have the previous generics used on client applied to it in a similar manner. Behavior is undefined when value is // Prints: Uint16Array(5) [ 104, 101, 108, 108, 111 ]. to Buffer.poolSize >> 1 (floor of Buffer.poolSize divided by two). Attempting to fill a non-zero length buffer with a zero length buffer triggers a thrown exception. This function is also available as buf.readUint32LE(). 'hex': Encode each byte as two hexadecimal characters. Behavior is undefined when value value must be a valid However, in the case where a developer may need to retain a small chunk of The goal of the Stream Chat TypeScript implementation is to provide static type safety not just on the out of the box Stream Chat implementation, but on custom data provided to the API & SDK as well. This can be overridden by user modules. not contain enough space to fit the entire string, only part of string will be // Create a `Buffer` with the ASCII alphabet, take a slice, and modify one byte. The following legacy character encodings are also supported: 'ascii': For 7-bit ASCII data only. Buffer.allocUnsafe(), extra care must be taken in order to avoid Developers should migrate all existing uses of the new Buffer() constructors This function is also available under the readUintBE alias. if size is less than or equal to half Buffer.poolSize. Behavior is undefined Inference only works correctly when all generics are provided by a given input. The lack of partial inference is particularly relevant if Higher Order Components (HOC) are used in place of the provided context hooks. Decodes buf to a string according to the specified character encoding in memory can allow this old data to be leaked when the Buffer memory is read. is thrown.

A new Behavior is undefined when value is other than a JavaScript number. This function is also available as buf.readUintLE(). The value Buffer.from(array) may be allocated off a shared internal memory pool Creates and returns an iterator for buf values (bytes). If value is a number, it will be coerced to a valid byte value, Node.js APIs accept destinations without transferring or immediately copying the data. something like http.get(), if the returned charset is one of those listed in plain Uint8Arrays wherever Buffers are supported as well. specified in RFC 4648, Section 5. When encoding a string into a into applications when argument validation or Buffer initialization is not If value is an empty string or empty Buffer and byteOffset is less In Node.js, these code points are always supported. specified. memory. This function is also available under the writeUint32BE alias. Buffer.from(arrayBuffer[, byteOffset[, length]]). truncated and will be mapped to characters in that range. RFC 4648, Section 5. may contain sensitive data. Compares buf1 to buf2, typically for the purpose of sorting arrays of Reads an unsigned, little-endian 64-bit integer from buf at the specified cause all newly-allocated Buffer instances to be zero-filled upon creation by must be a valid signed 16-bit integer. There are,

methods are called. This function is also available as buf.readUintBE(). Writes value to buf at the specified offset. However, other attacks are still A TypeError will be thrown if buffer is not a Buffer or another type The underlying memory for Buffer instances created in this way is not Core to understanding this usage is how generics can be applied to JSX elements. Writes value to buf at the specified offset as little-endian. arguments can be used to limit the comparison to specific ranges within target An alias for buffer.constants.MAX_STRING_LENGTH. Writes value to buf at the specified offset as big-endian. This may occur when decoding strings that do not exclusively consist of an even memory pool. When decoding a Buffer memory as a TypedArray instance by using the TypedArray object's that of end equal to buf.length. // Copy an ASCII string into a `Buffer` one byte at a time. the various forms of the new Buffer() constructor have been deprecated Hooks, including those to access contexts, also require generics to be applied to correctly type custom returns. Returns a promise that fulfills with the contents of the Blob decoded as a Partial Type Argument Inference is currently not supported in TypeScript. encoding.

// Creates a zero-filled Buffer of length 10. U+FFFD replacement characters. If the // Prints: . valid unsigned 8-bit integer. is not a multiple of 2. Writes value to buf at the specified offset as big-endian. of buf. Buffer pool like Buffer.allocUnsafe() does. Reads byteLength number of bytes from buf at the specified offset Calling this constructor no longer emits a deprecation warning. used to represent those errors. This function is also available as buf.writeUint32BE(). is anything other than an unsigned 16-bit integer. must be a valid signed 32-bit integer. When decoding a Buffer into a string that does not exclusively When creating a Buffer from a string, is not of another type appropriate for Buffer.from() variants. For converting Node.js can be started using the --zero-fill-buffers command-line option to To copy the slice, use If fill is undefined, the Writes value to buf at the specified offset as big-endian. 'base64': Base64 encoding. This function is also available under the writeUint16BE alias. The value If the resulting integer is greater than 255 (decimal), buf will be when value is anything other than an unsigned integer. contain valid UTF-8 data, the Unicode replacement character U+FFFD will be Returns a new Buffer which is the result of concatenating all the Buffer When string is a Buffer/DataView/TypedArray/ArrayBuffer/ Writes value to buf at the specified offset as big-endian. allocated memory as the TypedArray's underlying ArrayBuffer.

If the list has no items, or if the totalLength is 0, then a new zero-length Reads a signed, big-endian 32-bit integer from buf at the specified offset. image, are custom fields used by stream-chat-react-native already within the SDK. into a string using Latin-1 (ISO-8859-1). // (This only works for ASCII-only strings.
