Defined in: src/clients/decorators/arkivPublic.ts:18

Type Declaration

buildQuery()

buildQuery: () => QueryBuilder

Returns a QueryBuilder instance for building and executing queries. The QueryBuilder object follows the Builder pattern, allowing you to chain methods to build a query and then execute it.

Docs: https://docs.arkiv.network/ts-sdk/actions/public/query

Returns

QueryBuilder

A QueryBuilder instance for building and executing queries. QueryBuilder

Example

import { createPublicClient, http } from 'arkiv'
import { braga } from 'arkiv/chains'

const client = createPublicClient({
  chain: braga,
  transport: http(),
})
const query = client.buildQuery()
const entities = await query.where("key", "=", "value").ownedBy("0x123").fetch()

getBlockTiming()

getBlockTiming: () => Promise<{ blockDuration: number; currentBlock: bigint; currentBlockTime: number; }>

Returns the current block timing.

Returns

Promise<{ blockDuration: number; currentBlock: bigint; currentBlockTime: number; }>

The current block timing. GetBlockTimingReturnType

Example

import { createPublicClient, http } from 'arkiv'
import { braga } from 'arkiv/chains'

const client = createPublicClient({
  chain: braga,
  transport: http(),
})
const blockTiming = await client.getBlockTiming()
// {
//   currentBlock: 10n, // block number
//   currentBlockTime: 1234567890, // block timestamp
//   blockDuration: 2, // in seconds
// }

getEntity()

getEntity: (key) => Promise<Entity>

Returns the entity with the given key.

Docs: https://docs.arkiv.network/ts-sdk/actions/public/getEntity

Parameters

key

Hex

The entity key (hex string)

Returns

Promise<Entity>

The entity with the given key. Entity

Example

import { createPublicClient, http } from 'arkiv'
import { braga } from 'arkiv/chains'

const client = createPublicClient({
  chain: braga,
  transport: http(),
})
const entity = await client.getEntity("0x123")
// {
//   key: "0x123",
//   value: "0x123",
// }

getEntityCount()

getEntityCount: () => Promise<number>

Returns the number of entities in the DBChain.

Returns

Promise<number>

The number of entities in the DBChain

Example

import { createPublicClient, http } from 'arkiv'
import { braga } from 'arkiv/chains'

const client = createPublicClient({
  chain: braga,
  transport: http(),
})
const entityCount = await client.getEntityCount()
// entityCount = 0

query()

query: (query, queryOptions?) => Promise<QueryReturnType>

Returns a QueryResult instance for fetching the results of a raw query. If no query options are provided, all payload is included, but no metadata (like owner, expiredAt, etc.) and attributes.

Parameters

query

string

The raw query string

queryOptions?

QueryOptions

The optional query options - QueryOptions

Returns

Promise<QueryReturnType>

A QueryReturnType instance - QueryReturnType

Example

import { createPublicClient, http } from 'arkiv'
import { braga } from 'arkiv/chains'

const client = createPublicClient({
  chain: braga,
  transport: http(),
})
const queryResult = client.query('key = value && $owner = 0x123')
// queryResult = { entities: [{ key: "0x123", value: "0x123" }], cursor: undefined, blockNumber: undefined }
const queryResultWithOptions = client.query('key = value && $owner = 0x123', {
  includeData: {
    attributes: false,
    payload: true,
    metadata: true,
  },
  resultsPerPage: 10,
  cursor: undefined,
  atBlock: undefined,
})
// queryResultWithOptions = { entities: [{ key: "0x123", value: "0x123" }], cursor: "...", blockNumber: 32223n }

select()

select: {(selection?): SelectQueryBuilder<FullEntity>; <S>(selection): SelectQueryBuilder<ProjectedEntity<S>>; (selection): SelectQueryBuilder<FullEntity>; }

Returns a SelectQueryBuilder for building and executing queries — the recommended way to read entities. You declare up front which parts of an entity you want returned, so results always contain exactly the data you asked for.

Docs: https://docs.arkiv.network/ts-sdk/actions/public/query

Call Signature

(selection?): SelectQueryBuilder<FullEntity>

Select every field. Pass nothing or "*"; the returned entities contain all fields.

Parameters

selection?

"*"

Returns

SelectQueryBuilder<FullEntity>

Call Signature

<S>(selection): SelectQueryBuilder<ProjectedEntity<S>>

Pick the entity fields to return. Set the ones you want to true (at least one is required); the result is typed to exactly those fields, so reading anything else is a compile error.

Available fields: key, owner, creator, contentType, payload, attributes, expiresAtBlock, createdAtBlock, lastModifiedAtBlock, transactionIndexInBlock, operationIndexInTransaction.

Pass the selection inline so its fields stay literal true. A selection stored in a let/ const variable widens to boolean and the result type can no longer be narrowed — annotate it as const (e.g. const sel = { owner: true } as const) in that case.

Type Parameters

S

S extends EntitySelection

Parameters

selection

S

Returns

SelectQueryBuilder<ProjectedEntity<S>>

Example

client.select({ owner: true, attributes: true }) // entities typed { owner, attributes }
client.select({ key: true, payload: true })       // includes payload → toText()/toJson() too

Call Signature

(selection): SelectQueryBuilder<FullEntity>

Dynamic selection: accepts a value typed SelectArg (e.g. built at runtime). The result cannot be narrowed in this case, so the entities are typed as the full entity.

Parameters

selection

SelectArg

Returns

SelectQueryBuilder<FullEntity>

Param

What to include in the results. Omit it (or pass "*") to select everything, or pass an object to select specific parts (at least one field is required). Every part is opt-in, including the key. The selection is flat — each field maps to an entity field. SelectArg

Returns

A SelectQueryBuilder instance for building and executing queries. SelectQueryBuilder

Example

import { createPublicClient, http } from 'arkiv'
import { braga } from 'arkiv/chains'
import { eq } from 'arkiv/query'

const client = createPublicClient({
  chain: braga,
  transport: http(),
})
// select everything
await client.select().where(eq("category", "docs")).fetch()
await client.select("*").where(eq("category", "docs")).fetch()
// only the key
await client.select({ key: true }).where(eq("category", "docs")).fetch()
// select specific fields — result typed { owner: Hex; attributes: Attribute[] }
await client.select({ owner: true, attributes: true }).fetch()
// a single field — result typed { owner: Hex }
await client.select({ owner: true }).fetch()

subscribeEntityEvents()

subscribeEntityEvents: ({ onError, onEntityCreated, onEntityUpdated, onEntityDeleted, onEntityExpiresInExtended, }, pollingInterval?, fromBlock?) => Promise<() => void>

Subscribes to entity events. Takes an object with event handlers: {onError, onEntityCreated, onEntityUpdated, onEntityDeleted, onEntityExpiresInExtended}

Parameters

  onError,
  onEntityCreated,
  onEntityUpdated,
  onEntityDeleted,
  onEntityExpiresInExtended,

Returns

Promise<() => void>

A function to unsubscribe from the events

const client = createPublicClient({
  chain: braga,
  transport: http(),
})
const unsubscribe = await client.subscribeEntityEvents({
  onError: (error) => console.error("subscribeEntityEvents error", error),
})
unsubscribe() // unsubscribe from the events

Type Parameters
