The New web3.js - Release Candidate `rc.4`

v2.0.0-rc.4 (2024-11-05)

This version fixes a bug with program error decoding that we introduced in Release Candidate 2. We now expect this, Release Candidate 4, to be the final version before tagging version 2.0 of @solana/web3.js. Please submit any final bug reports before Thursday, November 7th by filing a GitHub Issue.

To install the Release Candidate:

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

• Try the runnable examples in the examples/ directory to get a feel for the API.
• Use the example dApp at https://solana-labs.github.io/solana-web3.js/example/ – source available here – for an example of how to build transactions with the new web3.js for use with wallets.
• Install TypeScript clients for on-chain programs like System and Token, then build a useful application or backend service.

Changelog since Release Candidate rc.3

• #3519 2798061 Thanks @lorisleiva! - Accept bigints in RPC error factories, fixing functions such as isProgramError

Changelog since Release Candidate rc.2

• #3507 45df702 Thanks @mcintyre94! - Fixed a bug where the subcription server's response would not be detected, because of a mismatch in the format of the id. Now all RPC message ids are strings, for avoidance of doubt.

Changelog since Release Candidate rc.1

• #3213 3fc388f Thanks @mcintyre94! - Clean up SolanaRpcApi: no longer extend RpcApiMethods + remove export

• #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.

• #3251 Thanks @ryoid! - isAddress() no longer throws despite that the input might be unparseable as a base-58 string. Now, it correctly, simply, returns false.

• #3361 441fa3a Thanks @steveluscher! - Fixed a bug where calls to isEd25519CurveSupported() might have resulted in uncaught rejections bubbling up through the app, in cases where Ed25519 is not supported

• #3134 38faba0 Thanks @buffalojoec! - Change unix timestamp type to bigint with an unsafe label

• #3128 0158b31 Thanks @lorisleiva! - Fix missing export in @solana/keys package. This means, the getPublicKeyFromPrivateKey function is now properly exported.

• #3407 10b08ac Thanks @lorisleiva! - Use RpcRequest, RpcResponse and their transformers in RPC Subscriptions packages

  This change makes the RPC and RPC Subscriptions architecture more consistent by using the same RpcRequest and RpcResponse types and transformers as the basis for handling user requests (RPC calls or subscriptions) and returning responses to them.

• #3201 02cefa7 Thanks @lorisleiva! - Update the response type of the getClusterNodes RPC method

• #3098 2f541b6 Thanks @buffalojoec! - Update program accounts filters for programAccounts query

• #3221 6b43588 Thanks @lorisleiva! - Add new isJsonRpcPayload helper method

• c8e6e71 Thanks @steveluscher! - We refactored the lower levels of the subscriptions API entirely.

  Previously, all layers of the subscriptions implementation, from the WebSocket transport to the API that developers use, dealt in AsyncIterables. These are notoriously difficult to code in such a way that expresses all of the ways in which a subscription might be cancelled or error out. Very slight omissions of care could open memory leaks that would bring down the simplest of apps. The new subscriptions infra in Release Candidate 2 deals with event-based subscriptions all the way up to the highest level API, at which point the subscription is vended to the application as an AsyncIterable.

  This has eliminated several classes of memory leak and has made it easier to implement higher-level transports (like the autopinger and the subscription coalescer). Additionally, this update introduces a new channel pool implementation that opens new WebSocket connections when existing ones become ‘full.’ Lastly, performance in the new implementation has been improved through a new demultiplexing utility that can separate message events into several channels based on arbitrary criteria, meaning you can apply transforms to the message right at the source, and vend subscriptions to downstream consumers that care only about one particular kind of message...

The New web3.js - Release Candidate `rc.1`

v2.0.0-rc.1 (2024-08-09)

Since we published the first Release Candidate of @solana/web3.js@2.0.0 your feedback has helped us to catch bugs that we missed during development. A special thank you today to @WilfredAlmeida the reports that led to the fixes in this, updated Release Candidate rc.1.

Also new in this release are handy tools that help you load key pairs and to derive public CryptoKey instances from private CryptoKey instances.

To install the Release Candidate:

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

• Try the runnable examples in the examples/ directory to get a feel for the API.
• Use the example dApp at https://solana-labs.github.io/solana-web3.js/example/ – source available here – for an example of how to build transactions with the new web3.js for use with wallets.
• Install TypeScript clients for on-chain programs like System and Token, then build a useful application or backend service.

Before the general release of web3.js, shortly before Breakpoint 2024 in September, we want to collect as much feedback as possible from you. If you find a bug, are missing a feature, or would like an API modified, file a GitHub Issue.

• #2928 bac3747 Thanks @steveluscher! - Added a useSignIn hook that, given a UiWallet or UiWalletAccount, returns a function that you can call to trigger a wallet's ‘Sign In With Solana’ feature.
• #2950 29821df Thanks @mcintyre94! - Refactor rpc-spec to remove requirement for transports to implement parts of JSON RPC spec
