From 776928c19928f865ab1c74c4754092e8e25a8746 Mon Sep 17 00:00:00 2001 From: kiryl Date: Wed, 6 May 2026 14:13:41 -0400 Subject: [PATCH] =?UTF-8?q?Docs=20redesign=20=E2=80=94=20week=204=20IA=20c?= =?UTF-8?q?utover?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Restructures the EN "Documentation" anchor into the 8 top-level groups from PRD §WS-1, consolidates the streaming taxonomy (LaserStream merges Yellowstone gRPC; WebSockets merges Standard + Enhanced), and ships 21 redirects to keep inbound links alive. Top-level groups (was 11, now 8 + Resources) - Get Started — adds /quickstart back into nav (was orphan) - Read chain state — RPC, indexed reads, DAS, Enhanced Tx, Wallet API - Stream chain data — LaserStream, WebSockets, Webhooks - Send transactions — Sender, Bundles, sendTransaction, Priority Fee - Run dedicated infrastructure — Dedicated Nodes, Shred Delivery - Specialized — Compression, Staking, Orb - Billing — autoscaling, pay-with-crypto - Resources — glossary, sdks, changelog Streaming consolidation - New websockets/ namespace: overview merges enhanced-websockets.mdx + rpc/websocket.mdx into one product page with two tiers (Enhanced + Standard) on a unified endpoint. Sub-pages moved here via git mv. - LaserStream absorbs Yellowstone gRPC: 5 monitoring guides moved under laserstream/guides/. New laserstream/migration-from-yellowstone page documents the wire-compatible drop-in (one URL change). Files moved (git mv, history preserved): 10 - data-streaming/quickstart → streaming/quickstart - grpc/{account,transaction,slot-and-block,entry,stream-pump-amm-data} → laserstream/guides/* - enhanced-websockets/{account-subscribe,transaction-subscribe, stream-pump-amm-data,llms.txt} → websockets/* - rpc/websocket/quickstart → websockets/quickstart Files deleted: 11 - data-streaming.mdx, getting-data.mdx (rewritten in week 2) - enhanced-websockets.mdx, rpc/websocket.mdx (merged into websockets/overview.mdx) - grpc.mdx, grpc/quickstart.mdx (merged into laserstream/migration-from-yellowstone.mdx) - rpc/websocket/stream-pump-amm-data.mdx (canonical is the enhanced-websockets version) - event-listening.mdx, event-listening/quickstart.mdx (orphan, redundant with streaming/) - laserstream/websocket.mdx (orphan, content covered by websockets/overview.mdx) - rpc/http/get-accounts.mdx, rpc/http/get-transactions.mdx (orphan duplicates of rpc/guides/*) Redirects added: 19 new entries on top of the 2 pre-existing, 21 total. - /grpc and /grpc/quickstart land on /laserstream/grpc (the gRPC product page) rather than the migration guide; the migration guide is a sibling page reachable from there. - All sub-paths (/grpc/account-monitoring, /enhanced-websockets/*, /rpc/websocket/*) redirect to their direct equivalents. - errors.404.redirect stays false so unmatched paths still 404 visibly. Internal-link rewrites: 70 occurrences across 33 files updated from old → new paths. Bulk-rewrite bug + fix: the rewriter's regex used a lookahead but no lookbehind, so /grpc matched as a substring of /laserstream/grpc and produced doubled paths like /laserstream/laserstream/migration-from- yellowstone. Caught by pre-commit review. 9 occurrences across 8 files re-pointed to /laserstream/grpc. Lessons captured in SPIKE-NOTES.md for future bulk rewrites. Audit: 361 EN pages (was 368). 333 in nav, 28 orphans (was 34). audit.csv prefilled for the 12 new/moved pages with their Diátaxis type and Keep action. Validation - docs.json is valid JSON. - mint validate parses all new files cleanly. The 2 pre-existing parse errors (api-reference/das/searchassets, api-reference/enhanced- transactions/gettransactions) are unrelated to this PR — they were also failing on main before this branch. - mint broken-links found no new broken links. Out of scope (deferred) - ZH side of docs.json nav — auto-regenerated by the i18n CI workflow on merge to main via npm run i18n:nav-apply. - Persona quickstarts (PRD §WS-4, week 3 in the plan). - API Reference anchor restructure — kept current shape per PRD. - Diátaxis page badges (PRD §WS-5, week 5). scripts/_ia-cutover.js stays in tree as a record of how the nav restructure happened. Not registered in package.json.

Within arrays, values operate as logical OR. - - - - - - Include/exclude vote transactions - - - - Include/exclude failed transactions - - - - Monitor specific transaction signature - - - - Include transactions involving any of these accounts (logical OR) - - - - Exclude transactions involving any of these accounts - - - - Include transactions involving all of these accounts (logical AND) - - - - - - Filter transactions and accounts within blocks - - - - Include all transactions within the block - - - - Include all account updates within the block - - - - Include all entries within the block - - - - - - When `true`, only receive slot updates for the specified commitment level. When `false`, receive updates for all commitment levels. - - - ---- - -## Example: Basic Transaction Monitoring - -Here's a complete example to get you started: - -```typescript -import Client, { CommitmentLevel, SubscribeRequest } from "@triton-one/yellowstone-grpc"; - -const client = new Client("your-grpc-endpoint", "your-api-token", { - "grpc.max_receive_message_length": 64 * 1024 * 1024 -}); - -const stream = await client.subscribe(); - -// Handle incoming data -stream.on("data", (data) => { - if (data.transaction) { - console.log(`Transaction: ${data.transaction.signature}`); - console.log(`Success: ${!data.transaction.meta?.err}`); - } -}); - -// Subscribe to transactions with complete request structure -const subscribeRequest: SubscribeRequest = { - transactions: { - client: { - accountInclude: [ - "TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA", // Token Program - "11111111111111111111111111111111" // System Program - ], - accountExclude: [], - accountRequired: [], - vote: false, - failed: false - } - }, - commitment: CommitmentLevel.CONFIRMED, - ping: { id: 1 } -}; - -stream.write(subscribeRequest); -``` - - -This is a basic example.

Current methods: - -* `transactionSubscribe` -* `accountSubscribe` - - -WebSockets have a 10-minute inactivity timer. Use health checks or send pings every minute to keep the connection alive. - - - -**Looking for Atlas WebSockets?**\ -If you need information on Atlas Enhanced WebSockets, please see our [Disclaimer](#disclaimer-transition-from-atlas-enhanced-websockets). - - -*** - -### Quickstart - -#### 1. Create a Basic WebSocket Client - -```bash -mkdir laserstream-enhanced-ws-demo -cd laserstream-enhanced-ws-demo -npm init -y -npm install ws -``` - -_(You only need the `ws` library for a Node.js WebSocket client. No additional libraries are strictly required.)_ - -#### 2. Obtain Your API Key - -Generate a key from the [Helius Dashboard](https://dashboard.helius.dev/). - -#### 3. Minimal Code Example - -Create an **`index.js`** file: - -```js -// index.js - -const WebSocket = require('ws'); - -// 1. Use the LaserStream Enhanced WebSockets endpoint (Mainnet example): -const WS_URL = `laserstream-ws-url`; - -const ws = new WebSocket(WS_URL); - -// 2.

To use it, provide a `TransactionSubscribeFilter` and optionally include `TransactionSubscribeOptions` for further customization. - -#### **TransactionSubscribeFilter** - -`vote`: A boolean flag to include/exclude vote-related transactions. - -`failed`: A boolean flag to include/exclude transactions that failed. - -`signature`: Filters updates to a specific transaction based on its signature. - -`accountInclude`: A list of accounts for which you want to receive transaction updates. This means that only one of the accounts must be included in the transaction updates (e.g., Account 1 OR Account 2). - -`accountExclude`: A list of accounts you want to exclude from transaction updates. - -`accountRequired`: Transactions must involve these specified accounts to be included in updates. This means that all of the accounts must be included in the transaction updates (e.g., Account 1 AND Account 2). - - -You can include up to 50,000 addresses in the `accountInclude`, `accountExclude` and `accountRequired` arrays. - - -#### **TransactionSubscribeOptions (Optional)** - -`commitment`: Specifies the commitment level for fetching data, dictating at what stage of the transaction lifecycle updates are sent. The possible values are **processed**, **confirmed** and **finalized** - -`encoding`: Sets the encoding format of the returned transaction data. The possible values are **base58**, **base64** and **jsonParsed** - -`transactionDetails` : Determines the level of detail for the returned transaction data. The possible values are **full, signatures, accounts** and **none** - -`showRewards`: A boolean flag indicating if reward data should be included in the transaction updates. - -`maxSupportedTransactionVersion`: Specifies the highest version of transactions you want to receive updates. To get Versioned Transactions, set the value to 1. - -`fromSlot`: Begin the subscription from a specific Solana slot, replaying any relevant transactions from that slot forward until you catch up to real-time data. - - -`maxSupportedTransactionVersion` is required to return the accounts and full-level details of a given transaction (i.e., `transactionDetails: "accounts" | "full"`). - - -#### Transaction Subscribe Example - -
