function parse | Bun module | Bun

Parse a JSONL (JSON Lines) string into an array of JavaScript values.

If a parse error occurs and no values were successfully parsed, throws a SyntaxError. If values were parsed before the error, returns the successfully parsed values without throwing.

Incomplete trailing values (e.g. from a partial chunk) are silently ignored and not included in the result.

When a TypedArray is passed, the bytes are parsed directly without copying if the content is ASCII.

The JSONL string or typed array to parse

An array of parsed values

const items = Bun.JSONL.parse('{"a":1}\n{"b":2}\n');
// [{ a: 1 }, { b: 2 }]

// From a Uint8Array (zero-copy for ASCII):
const buf = new TextEncoder().encode('{"a":1}\n{"b":2}\n');
const items = Bun.JSONL.parse(buf);
// [{ a: 1 }, { b: 2 }]

// Partial results on error after valid values:
const partial = Bun.JSONL.parse('{"a":1}\n{bad}\n');
// [{ a: 1 }]

// Throws when no valid values precede the error:
Bun.JSONL.parse('{bad}\n'); // throws SyntaxError

Represents a raw buffer of binary data, which is used to store data for the different typed arrays. ArrayBuffers cannot be read from or written to directly, but can be passed to a typed array or DataView Object to interpret the raw buffer as needed.

Read-only. The length of the ArrayBuffer (in bytes).

Resizes the ArrayBuffer to the specified size (in bytes).

MDN

Resize an ArrayBuffer in-place.

Returns a section of an ArrayBuffer.

Creates a new ArrayBuffer with the same byte content as this buffer, then detaches this buffer.

MDN

Creates a new non-resizable ArrayBuffer with the same byte content as this buffer, then detaches this buffer.
