Cardano Ogmios TypeScript Client Packages - REPL

A Node.js REPL which exposes the client behaviour in a terminal. Loaded into the context are the client builder functions, isolated query functions, and an instance of ChainSyncClient as chainSync with handlers to log the returned data. On exit the chainSync instance is shutdown. Optionally pass --host and --port arguments to specify the Ogmios server connection.

Changelog

[6.2.0] - 2024-03-22

Added

• Transaction evaluation now automatically UTxO available from processing the mempool. This allows for chaining smart-contract transactions without the need to track the UTxO state on from the client's side. Ogmios now internally maintains a view of the node's mempool and ensure a consistent access to it when evaluating transaction. See also #375.

• More log traces around transaction evaluation and submission.

Changed

• Retry HasTx on false with id wrapped in different eras, to cope with the hard-fork combinator inability to compare transaction id across eras. See also #376.

Removed

• N/A
