Version 2.0.0-next.1

Major changes

chore: fix changeset type (#1220) (opens in a new tab) (@latticexyz/store-indexer, @latticexyz/store-sync)

Adds store indexer service package with utils to query the indexer service.

You can run the indexer locally by checking out the MUD monorepo, installing/building everything, and running pnpm start:local from packages/store-indexer.

To query the indexer in the client, you can create a tRPC client with a URL pointing to the indexer service and call the available tRPC methods:

import { createIndexerClient } from "@latticexyz/store-sync/trpc-indexer";
 
const indexer = createIndexerClient({ url: indexerUrl });
const result = await indexer.findAll.query({
  chainId: publicClient.chain.id,
  address,
});

If you're using syncToRecs, you can just pass in the indexerUrl option as a shortcut to the above:

import { syncToRecs } from "@latticexyz/store-sync/recs";
 
syncToRecs({
  ...
  indexerUrl: "https://your.indexer.service",
});

feat(common): replace TableId with tableIdToHex/hexToTableId (#1258) (opens in a new tab) (@latticexyz/cli, @latticexyz/common, @latticexyz/dev-tools, @latticexyz/network, @latticexyz/std-client, @latticexyz/store-sync)

Add tableIdToHex and hexToTableId pure functions and move/deprecate TableId.

feat(common): add createContract, createNonceManager utils (#1261) (opens in a new tab) (@latticexyz/common)

Add utils for using viem with MUD

  • createContract is a wrapper around viem's getContract (opens in a new tab) but with better nonce handling for faster executing of transactions. It has the same arguments and return type as getContract.
  • createNonceManager helps track local nonces, used by createContract.

Also renames mudTransportObserver to transportObserver.

Minor changes

feat(common): add viem utils (#1245) (opens in a new tab) (@latticexyz/common)

Add utils for using viem with MUD

  • mudFoundry chain with a transaction request formatter that temporarily removes max fees to work better with anvil --base-fee 0
  • createBurnerAccount that also temporarily removes max fees during transaction signing to work better with anvil --base-fee 0
  • mudTransportObserver that will soon let MUD Dev Tools observe transactions

You can use them like:

import { createBurnerAccount, mudTransportObserver } from "@latticexyz/common";
import { mudFoundry } from "@latticexyz/common/chains";
 
createWalletClient({
  account: createBurnerAccount(privateKey),
  chain: mudFoundry,
  transport: mudTransportObserver(http()),
  pollingInterval: 1000,
});

feat(store-indexer,store-sync): make chain optional, configure indexer with RPC (#1234) (opens in a new tab) (@latticexyz/store-indexer, @latticexyz/store-sync)

  • Accept a plain viem PublicClient (instead of requiring a Chain to be set) in store-sync and store-indexer functions. These functions now fetch chain ID using publicClient.getChainId() when no publicClient.chain.id is present.
  • Allow configuring store-indexer with a set of RPC URLs (RPC_HTTP_URL and RPC_WS_URL) instead of CHAIN_ID.

feat(store-sync): export singletonEntity as const, allow startBlock in syncToRecs (#1235) (opens in a new tab) (@latticexyz/store-sync)

Export singletonEntity as const rather than within the syncToRecs result.

- const { singletonEntity, ... } = syncToRecs({ ... });
+ import { singletonEntity, syncToRecs } from "@latticexyz/store-sync/recs";
+ const { ... } = syncToRecs({ ... });

feat(schema-type): add type narrowing isStaticAbiType (#1196) (opens in a new tab) (@latticexyz/schema-type)

add type narrowing isStaticAbiType

feat(common): move zero gas fee override to createContract (#1266) (opens in a new tab) (@latticexyz/common)

Patch changes

fix(cli): add support for legacy transactions in deploy script (#1178) (opens in a new tab) (@latticexyz/cli)

Add support for legacy transactions in deploy script by falling back to gasPrice if lastBaseFeePerGas is not available

feat: protocol-parser in go (#1116) (opens in a new tab) (@latticexyz/services)

protocol-parser in Go

refactor(store): optimize Storage library (#1194) (opens in a new tab) (@latticexyz/store)

Optimize storage library

feat(store-sync): add block numbers to SyncProgress (#1228) (opens in a new tab) (@latticexyz/store-sync)

Adds latestBlockNumber and lastBlockNumberProcessed to internal SyncProgress component

feat(store-sync): sync to RECS (#1197) (opens in a new tab) (@latticexyz/store-sync)

Add RECS sync strategy and corresponding utils

import { createPublicClient, http } from 'viem';
import { syncToRecs } from '@latticexyz/store-sync';
import storeConfig from 'contracts/mud.config';
import { defineContractComponents } from './defineContractComponents';
 
const publicClient = createPublicClient({
  chain,
  transport: http(),
  pollingInterval: 1000,
});
 
const { components, singletonEntity, latestBlock$, blockStorageOperations$, waitForTransaction } = await syncToRecs({
  world,
  config: storeConfig,
  address: '0x...',
  publicClient,
  components: defineContractComponents(...),
});

fix(store): align Store event names between IStoreWrite and StoreCore (#1237) (opens in a new tab) (@latticexyz/store)

Align Store events parameter naming between IStoreWrite and StoreCore

fix(cli): explicit import of world as type (#1206) (opens in a new tab) (@latticexyz/cli, @latticexyz/std-client)

Generated contractComponents now properly import World as type

feat(store-sync): export singletonEntity as const, allow startBlock in syncToRecs (#1235) (opens in a new tab) (@latticexyz/store-sync)

Add startBlock option to syncToRecs.

import { syncToRecs } from "@latticexyz/store-sync/recs";
import worlds from "contracts/worlds.json";
 
syncToRecs({
  startBlock: worlds['31337'].blockNumber,
  ...
});

feat(store-sync): sync to sqlite (#1185) (opens in a new tab) (@latticexyz/network)

Remove devEmit function when sending network events from SyncWorker because they can't be serialized across the web worker boundary.

feat(cli,recs,std-client): update RECS components with v2 key/value schemas (#1195) (opens in a new tab) (@latticexyz/cli, @latticexyz/recs, @latticexyz/std-client)

Update RECS components with v2 key/value schemas. This helps with encoding/decoding composite keys and strong types for keys/values.

This may break if you were previously dependent on component.id, component.metadata.componentId, or component.metadata.tableId:

  • component.id is now the on-chain bytes32 hex representation of the table ID
  • component.metadata.componentName is the table name (e.g. Position)
  • component.metadata.tableName is the namespaced table name (e.g. myworld:Position)
  • component.metadata.keySchema is an object with key names and their corresponding ABI types
  • component.metadata.valueSchema is an object with field names and their corresponding ABI types

refactor(store): update tightcoder codegen, optimize TightCoder library (#1210) (opens in a new tab) (@latticexyz/common, @latticexyz/store, @latticexyz/world)

  • Refactor tightcoder to use typescript functions instead of ejs
  • Optimize TightCoder library
  • Add isLeftAligned and getLeftPaddingBits common codegen helpers

Version 2.0.0-next.0

Minor changes

feat(store-sync): add store sync package (#1075) (opens in a new tab) (@latticexyz/block-logs-stream, @latticexyz/protocol-parser, @latticexyz/store-sync, @latticexyz/store)

Add store sync package

feat(protocol-parser): add abiTypesToSchema (#1100) (opens in a new tab) (@latticexyz/protocol-parser)

chore(protocol-parser): add changeset for #1099 (#1111) (opens in a new tab) (@latticexyz/protocol-parser)

feat: add encodeKeyTuple, a util to encode key tuples in Typescript (equivalent to key tuple encoding in Solidity and inverse of decodeKeyTuple). Example:

encodeKeyTuple({ staticFields: ["uint256", "int32", "bytes16", "address", "bool", "int8"], dynamicFields: [] }, [
  42n,
  -42,
  "0x12340000000000000000000000000000",
  "0xFFfFfFffFFfffFFfFFfFFFFFffFFFffffFfFFFfF",
  true,
  3,
]);
// [
//  "0x000000000000000000000000000000000000000000000000000000000000002a",
//  "0xffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffd6",
//  "0x1234000000000000000000000000000000000000000000000000000000000000",
//  "0x000000000000000000000000ffffffffffffffffffffffffffffffffffffffff",
//  "0x0000000000000000000000000000000000000000000000000000000000000001",
//  "0x0000000000000000000000000000000000000000000000000000000000000003",
// ]

feat(store-sync): rework blockLogsToStorage (#1176) (opens in a new tab) (@latticexyz/block-logs-stream, @latticexyz/store-sync)

  • Replace blockEventsToStorage with blockLogsToStorage that exposes a storeOperations callback to perform database writes from store operations. This helps encapsulates database adapters into a single wrapper/instance of blockLogsToStorage and allows for wrapping a block of store operations in a database transaction.
  • Add toBlock option to groupLogsByBlockNumber and remove blockHash from results. This helps track the last block number for a given set of logs when used in the context of RxJS streams.

feat(block-logs-stream): add block logs stream package (#1070) (opens in a new tab) (@latticexyz/block-logs-stream)

Add block logs stream package

import { filter, map, mergeMap } from "rxjs";
import { createPublicClient, parseAbi } from "viem";
import {
  createBlockStream,
  isNonPendingBlock,
  groupLogsByBlockNumber,
  blockRangeToLogs,
} from "@latticexyz/block-logs-stream";
 
const publicClient = createPublicClient({
  // your viem public client config here
});
 
const latestBlock$ = await createBlockStream({ publicClient, blockTag: "latest" });
 
const latestBlockNumber$ = latestBlock$.pipe(
  filter(isNonPendingBlock),
  map((block) => block.number)
);
 
latestBlockNumber$
  .pipe(
    map((latestBlockNumber) => ({ startBlock: 0n, endBlock: latestBlockNumber })),
    blockRangeToLogs({
      publicClient,
      address,
      events: parseAbi([
        "event StoreDeleteRecord(bytes32 table, bytes32[] key)",
        "event StoreSetField(bytes32 table, bytes32[] key, uint8 schemaIndex, bytes data)",
        "event StoreSetRecord(bytes32 table, bytes32[] key, bytes data)",
        "event StoreEphemeralRecord(bytes32 table, bytes32[] key, bytes data)",
      ]),
    }),
    mergeMap(({ logs }) => from(groupLogsByBlockNumber(logs)))
  )
  .subscribe((block) => {
    console.log("got events for block", block);
  });

feat(gas-report): create package, move relevant files to it (#1147) (opens in a new tab) (@latticexyz/cli, @latticexyz/gas-report, @latticexyz/store)

Create gas-report package, move gas-report cli command and GasReporter contract to it

refactor(store,world): replace isStore with storeAddress (#1061) (opens in a new tab) (@latticexyz/std-contracts, @latticexyz/store, @latticexyz/world)

Rename MudV2Test to MudTest and move from @latticexyz/std-contracts to @latticexyz/store.

// old import
import { MudV2Test } from "@latticexyz/std-contracts/src/test/MudV2Test.t.sol";
// new import
import { MudTest } from "@latticexyz/store/src/MudTest.sol";

Refactor StoreSwitch to use a storage slot instead of function isStore() to determine which contract is Store:

  • Previously StoreSwitch called isStore() on msg.sender to determine if msg.sender is a Store contract. If the call succeeded, the Store methods were called on msg.sender, otherwise the data was written to the own storage.
  • With this change StoreSwitch instead checks for an address in a known storage slot. If the address equals the own address, data is written to the own storage. If it is an external address, Store methods are called on this address. If it is unset (address(0)), store methods are called on msg.sender.
  • In practice this has the same effect as before: By default the World contracts sets its own address in StoreSwitch, while System contracts keep the Store address undefined, so Systems write to their caller (World) if they are executed via call or directly to the World storage if they are executed via delegatecall.
  • Besides gas savings, this change has two additional benefits:
    1. it is now possible for Systems to explicitly set a Store address to make them exclusive to that Store and
    2. table libraries can now be used in tests without having to provide an explicit Store argument, because the MudTest base contract redirects reads and writes to the internal World contract.

feat(store-sync): sync to sqlite (#1185) (opens in a new tab) (@latticexyz/store-sync)

blockLogsToStorage(sqliteStorage(...)) converts block logs to SQLite operations. You can use it like:

import { drizzle } from "drizzle-orm/better-sqlite3";
import Database from "better-sqlite3";
import { BaseSQLiteDatabase } from "drizzle-orm/sqlite-core";
import { createPublicClient } from "viem";
import { blockLogsToStorage } from "@latticexyz/store-sync";
import { sqliteStorage } from "@latticexyz/store-sync/sqlite";
 
const database = drizzle(new Database('store.db')) as any as BaseSQLiteDatabase<"sync", void>;
const publicClient = createPublicClient({ ... });
 
blockLogs$
  .pipe(
    concatMap(blockLogsToStorage(sqliteStorage({ database, publicClient }))),
    tap(({ blockNumber, operations }) => {
      console.log("stored", operations.length, "operations for block", blockNumber);
    })
  )
  .subscribe();

feat(common): new utils, truncate table ID parts (#1173) (opens in a new tab) (@latticexyz/common)

TableId.toHex() now truncates name/namespace to 16 bytes each, to properly fit into a bytes32 hex string.

Also adds a few utils we'll need in the indexer:

  • bigIntMin is similar to Math.min but for bigints
  • bigIntMax is similar to Math.max but for bigints
  • bigIntSort for sorting an array of bigints
  • chunk to split an array into chunks
  • wait returns a Promise that resolves after specified number of milliseconds

feat(cli): update set-version to match new release structure, add --tag, --commit (#1157) (opens in a new tab) (@latticexyz/cli)

  • update the set-version cli command to work with the new release process by adding two new options:
    • --tag: install the latest version of the given tag. For snapshot releases tags correspond to the branch name, commits to main result in an automatic snapshot release, so --tag main is equivalent to what used to be -v canary
    • --commit: install a version based on a given commit hash. Since commits from main result in an automatic snapshot release it works for all commits on main, and it works for manual snapshot releases from branches other than main
  • set-version now updates all package.json nested below the current working directory (expect node_modules), so no need for running it each workspace of a monorepo separately.

Example:

pnpm mud set-version --tag main && pnpm install
pnpm mud set-version --commit db19ea39 && pnpm install
