idxs

TypeScript Interface for Index Supply.

Install

``bash
npm i idxs
`

Usage

$3

Instantiate and use the IndexSupply client to fetch data from the Index Supply API.

`ts
import { IndexSupply } from 'idxs'

const is = IndexSupply.create()

// Fetch transactions
const txs = await is.fetch({
query: 'select hash, "from", "to", value from txs where chain = 1 limit 10',
})
console.log(txs.rows)

// Fetch Transfer events with ABI signature
const transfers = await is.fetch({
query: 'select "from", "to", value from transfer where chain = 1 limit 10',
signatures: ['event Transfer(address indexed from, address indexed to, uint256 value)'],
})
console.log(transfers.rows)

// Pagination with cursor
const next = await is.fetch({
query: 'select hash, "from", "to", value from txs where chain = 1 limit 10',
cursor: txs.cursor,
})

// Live streaming
for await (const result of is.live({
query: 'select hash, "from", "to" from txs where chain = 1 limit 10',
}))
console.log(result.rows)

`

$3

idxs exports a Kysely-based type-safe query builder.

`ts
import { IndexSupply, QueryBuilder } from 'idxs'

const is = IndexSupply.create()
const qb = QueryBuilder.from(is)

// Query standard tables
const txs = await qb
.selectFrom('txs')
.select(['hash', 'from', 'to', 'value'])
.where('chain', '=', 1)
.limit(10)
.execute()

// Query with event signatures
const transfers = await qb
.withSignatures(['event Transfer(address indexed from, address indexed to, uint256 value)'])
.selectFrom('transfer')
.select(['from', 'to', 'value'])
.where('chain', '=', 1)
.limit(100)
.execute()

// Pagination with cursor
const next = await qb
.atCursor(txs.cursor)
.selectFrom('txs')
.select(['hash'])
.limit(10)
.execute()

// Live streaming
for await (const txs of qb
.selectFrom('txs')
.select(['hash', 'from', 'to', 'value'])
.where('chain', '=', 1)
.stream()
)
console.log(txs)
