NEAR Lake Framework
NEAR Lake Framework is a syntactical framework for accessing the NEAR Lake Indexer Data. It is a wrapper around the AWS API.
Has @near-lake/primitives
as a dependency, which contains the types for the data with associated helper functions.
Simple Example
import { startStream, types } from '@near-lake/framework';
const lakeConfig: types.LakeConfig = {
s3BucketName: 'near-lake-data-mainnet',
s3RegionName: 'eu-central-1',
startBlockHeight: 66264389,
};
async function handleBlock(
block: types.Block,
context: types.LakeContext
): Promise<void> {
// custom logic for handling the block
let events = block.eventsByAccountId("x.paras.near")
console.log(events)
}
(async () => {
await startStream(lakeConfig, handleStreamerMessage);
})();
The main function in this example is handleBlock(block, context)
, which contains custom logic for how to handle a given block. block
is of type Block
from @near-lake/primitives
which gives access to helper methods to make it easier to extract data. You may find a list of helper functions here.
