This includes a WebAssembly binary, so you probably want to import it asynchronously, like so: + +```js +import('blake3/browser').then(blake3 => { + blake3.hash('foo'); // => Uint8Array +}); +``` + +The API is very similar in Node.js and browsers, but Node supports and returns Buffers and a wider range of input and output encoding. + +More complete example: + +```js +const { hash, createHash } = require('blake3'); + +hash('some string'); // => hash a string to a uint8array + +// Update incrementally (Node and Browsers): +const hash = createHash(); +stream.on('data', d => hash.update(d)); +stream.on('error', err => { + // hashes use unmanaged memory in WebAssembly, always free them if you don't digest()! + hash.dispose(); + throw err; +}); +stream.on('end', () => finishedHash(hash.digest())); + +// Or, in Node, it's also a transform stream: +createReadStream('file.txt') + .pipe(createHash()) + .on('data', hash => console.log(hash.toString('hex'))); +``` + +## API + +### Node.js + +The Node API can be imported via `require('blake3')`. + +#### `hash(data: BinaryLike, options?: { length: number }): Buffer` + +Returns a hash for the given data. The data can be a string, buffer, typedarray, array buffer, or array. By default, it generates the first 32 bytes of the hash for the data, but this is configurable. It returns a Buffer. + +#### `keyedHash(key: Buffer, data: BinaryLike, options?: { length: number }): Buffer` + +Returns keyed a hash for the given data. The key must be exactly 32 bytes. The data can be a string, buffer, typedarray, array buffer, or array. By default, it generates the first 32 bytes of the hash for the data, but this is configurable. It returns a Buffer. + +For more information, see [the blake3 docs](https://docs.rs/blake3/0.1.3/blake3/fn.keyed_hash.html). + +#### `deriveKey(context: string, material: BinaryLike, options?: { length: number }): Buffer` + +The key derivation function. The data can be a string, buffer, typedarray, array buffer, or array. By default, it generates the first 32 bytes of the hash for the data, but this is configurable. It returns a Buffer. + +For more information, see [the blake3 docs](https://docs.rs/blake3/0.1.3/blake3/fn.derive_key.html). + +#### Hasher + +The hasher is a type that lets you incrementally build a hash. It's compatible with Node's crypto hash instance. For instance, it implements a transform stream, so you could do something like: + +```js +createReadStream('file.txt') + .pipe(createHash()) + .on('data', hash => console.log(hash.toString('hex'))); +``` + +##### `createHash(): Hasher` + +Creates a new hasher instance using the standard hash function. + +##### `createKeyed(key: Buffer): Hasher` + +Creates a new hasher instance for a keyed hash.

The data can be a string, buffer, typedarray, array buffer, or array. This will throw if called after `digest()` or `dispose()`. + +##### `hasher.digest(encoding?: string, options?: { length: number, dispose: boolean })): Buffer | string` + +Returns the hash of the data. If an `encoding` is given, a string will be returned. Otherwise, a Buffer is returned. Optionally, you can specify the requested byte length of the hash. + +If `dispose: false` is given in the options, the hash will not automatically be disposed of, allowing you to continue updating it after obtaining the current reader. + +##### `hasher.reader(options?: { dispose: boolean }): HashReader` + +Returns a [HashReader](#HashReader) for the current hash. + +If `dispose: false` is given in the options, the hash will not automatically be disposed of, allowing you to continue updating it after obtaining the current reader. + +##### `hasher.dispose()` + +Disposes of unmanaged resources. You should _always_ call this if you don't call `digest()` to free umanaged (WebAssembly-based) memory. + +#### HashReader + +The hash reader can be returned from hashing functions. Up to 264-1 bytes of data can be read from BLAKE3 hashes; this structure lets you read those. Note that, like `hash`, this is an object which needs to be manually disposed of. + +##### `reader.position: bigint` + +A property which gets or sets the position of the reader in the output stream. A `RangeError` is thrown if setting this to a value less than 0 or greater than 264-1. Note that this is a bigint, not a standard number. + +```js +reader.position += 32n; // advance the reader 32 bytes +``` + +##### `reader.readInto(target: Buffer): void` + +Reads bytes into the target array, filling it up and advancing the reader's position. A `RangeError` is thrown if reading this data puts the reader past 264-1 bytes. + +##### `reader.read(bytes: number): Buffer` + +Reads and returns the given number of bytes from the reader, and advances the position. A `RangeError` is thrown if reading this data puts the reader past 264-1 bytes. + +##### `reader.toString([encoding]): string` + +Converts first 32 bytes of the hash to a string with the given encoding. Defaults to hex encoding. + +##### `reader.toBuffer(): Buffer` + +Converts first 32 bytes of the hash to a Buffer. + +##### `reader.dispose()` + +Disposes of unmanaged resources. You should _always_ call this to free umanaged (WebAssembly-based) memory, or you application will leak memory. + +#### `using(disposable: IDisposable, fn: disposable => T): T` + +A helper method that takes a disposable, and automatically calls the dispose method when the function returns, or the promise returned from the function is settled. + +```js +// read and auto-dispose the first 64 bytes +const first64Bytes = using(hash.reader(), reader => reader.toBuffer(64)); + +// you can also return promises/use async methods: +using(hash.reader(), async reader => { + do { + await send(reader.read(64)); + } while (needsMoreData()); +}); +``` + +### Browser + +The browser API can be imported via `import('blake3/browser')`, which works well with Webpack. + +If you aren't using a bundler or using a more "pure" bundler like Parcel, you can import `blake3/browser-async` which exports a function to asynchronously load the WebAssembly code and resolves to the package contents. + +```js +import load from 'blake3/browser-async'; + +load().then(blake3 => { + console.log(blake3.hash('hello world')); +}); +``` + +#### `hash(data: BinaryLike, options?: { length: number }): Hash` + +Returns a hash for the given data. The data can be a string, typedarray, array buffer, or array. By default, it generates the first 32 bytes of the hash for the data, but this is configurable. It returns a [Hash](#Hash) instance. + +#### `keyedHash(key: Buffer, data: BinaryLike, options?: { length: number }): Hash` + +Returns keyed a hash for the given data.

Get all your code ready to go in master, pushed up to Github. +2. Run `make prepare-binaries`. This will update the branch `generate-binary`, which kicks off a build via Github actions to create `.node` binaries for every relevant Node.js version. +3. When the build completes, it'll generate a zip file of artifacts. Download those. +4. Back on master, run `npm version ` to update the version in git. `git push --tags`. +5. On Github, upload the contents of the artifacts folder to the release for the newly tagged version. +6.
