Patch Changes

  • #2434 31916ae Thanks @lorisleiva! - Renamed mapCodec to transformCodec

  • #2397 a548de2 Thanks @lorisleiva! - Added a new addCodecSizePrefix primitive

    const codec = addCodecSizePrefix(getBase58Codec(), getU32Codec());

codec.encode('hello world');
// 0x0b00000068656c6c6f20776f726c64
//   |       └-- Our encoded base-58 string.
//   └-- Our encoded u32 size prefix.

  • #2419 89f399d Thanks @lorisleiva! - Added new addCodecSentinel primitive

    The addCodecSentinel function provides a new way of delimiting the size of a codec. It allows us to add a sentinel to the end of the encoded data and to read until that sentinel is found when decoding. It accepts any codec and a Uint8Array sentinel responsible for delimiting the encoded data.

    const codec = addCodecSentinel(getUtf8Codec(), new Uint8Array([255, 255]));
codec.encode('hello');
// 0x68656c6c6fffff
//   |        └-- Our sentinel.
//   └-- Our encoded string.

  • #2400 ebb03cd Thanks @lorisleiva! - Added new containsBytes and getConstantCodec helpers

    The containsBytes helper checks if a Uint8Array contains another Uint8Array at a given offset.

    containsBytes(new Uint8Array([1, 2, 3, 4]), new Uint8Array([2, 3]), 1); // true
containsBytes(new Uint8Array([1, 2, 3, 4]), new Uint8Array([2, 3]), 2); // false

    The getConstantCodec function accepts any Uint8Array and returns a Codec<void>. When encoding, it will set the provided Uint8Array as-is. When decoding, it will assert that the next bytes contain the provided Uint8Array and move the offset forward.

    const codec = getConstantCodec(new Uint8Array([1, 2, 3]));

codec.encode(undefined); // 0x010203
codec.decode(new Uint8Array([1, 2, 3])); // undefined
codec.decode(new Uint8Array([1, 2, 4])); // Throws an error.

  • #2383 ce1be3f Thanks @lorisleiva! - getScalarEnumCodec is now called getEnumCodec

  • #3541 135dc5a Thanks @steveluscher! - Drop the Release Candidate label and publish @solana/web3.js at version 2.0.0

  • #2382 7e86583 Thanks @lorisleiva! - getDataEnumCodec is now called getDiscriminatedUnionCodec

  • #2411 2e5af9f Thanks @lorisleiva! - Renamed fixCodec to fixCodecSize

  • #2606 367b8ad Thanks @lorisleiva! - Use commonjs package type

  • #3137 fd72c2e Thanks @mcintyre94! - The build is now compatible with the Vercel Edge runtime and Cloudflare Workers through the addition of edge-light and workerd to the package exports.

  • Updated dependencies [9370133, 89f399d, ebb03cd, ce1be3f, 82cf07f, 2d54650, 135dc5a, bef9604, 7e86583, 4f19842, 677a9c4, 38faba0, 2798061, be36bab, 288029a, 4ae78f5, 478443f, 367b8ad, fd72c2e]:

2.0.0-preview.2

Patch Changes

  • The first Technology Preview of @solana/web3.js 2.0 was released at the Breakpoint conference in November 2023. Based on your feedback, we want to get a second version of it into your hands now with some changes, bug fixes, and new features.

    To install the second Technology Preview:

    npm install --save @solana/web3.js@tp2

    Most notably, this release integrates with the new JavaScript client generator for on-chain programs. Instruction creators and account decoders can now be autogenerated for any program, including your own! Read more here, and check out the growing list of autogenerated core programs here.
