Full Changelog: v0.6.0...v0.7.0

v0.6.0

Substreams now supports authenticating by passing X-Api-Key in the Header of the gRPC request, no need for creating JWT anymore (saves one less step in the auth process).

Additionally, Substreams endpoint support native ConnectWeb directly in the browser using the @substreams/node library by using createWebTransport.

What's New?

• Replace Basic Auth => header X-Api-Key (not JWT token)
• Rename header for User-Agent => X-User-Agent
  • add defaultHeadersInterceptor which uses {"X-User-Agent": "@substreams/node"}
• fix createHeadersInterceptor to include headers as interceptor (previously wasn't adding any headers)
• Update examples to use SUBSTREAMS_API_KEY instead of SUBSTREAMS_API_TOKEN

What's Breaking?

• Add custom exports to node & web Transports
  • Allows to import @substreams/node directly in browser application without importing NodeJS specific dependencies

import { BlockEmitter } from "@substreams/node";
import { createNodeTransport } from "@substreams/node/createNodeTransport";
// or
import { createWebTransport } from "@substreams/node/createWebTransport";

What's Changed

• Update auth api key & export to web/node by @DenisCarriere in #11

v0.5.3

• update to latest dependencies

v0.5.2

v0.5.0

Changes

• Replace createPromiseClient with createCallbackClient
• Replace emitter.stop() function with CancelFn from Callback Client

Example

const cancel = emitter.start();

// Cancel after 3 seconds
setTimeout(cancel, 3000);

New event emitters

• close
• fatalError

type LocalEventTypes = {
  close: [error?: ConnectError];
  fatalError: [error: FatalError];
};

Examples

// End of Stream
emitter.on("close", (error) => {
  if (error) {
    console.error(error);
  }
});

// Fatal error
emitter.on("fatalError", (error) => {
  console.error(error);
});

What's Changed

• Implement CallbackClient by @DenisCarriere in #9

Transport exports

import { createNodeTransport } from "@substreams/node";

Full Changelog: v0.4.3...v0.4.4

v0.4.3

• Switch back to using connect-node HTTP 2.0
  • connect-web isn't stable either

Bun 1.0.13 now includes HTTP 2.0 support https://bun.sh/blog/bun-v1.0.13

v0.4.2

• FIX: Do not include auth headers if no token is provided

v0.4.1

What's Changed

• drop the connect-node in favour of connect-web

Reason: Bun can't compile using HTTP2 at the moment, where it does work with connect-web

Whenever bun can compile into HTTP2, we can add back support for connect-node

v0.4.0

What's Changed

• Replaced @bufbuild/connect deprecated dependency with @connectrpc by @chamorin in #7
