@polkadot/api 2.5.1

v2.5.1

on Node.js NPM

Upgrade priority: Low. Recommended for api-contract developers.

• Breaking change Substrate changed the ContractExecResult from api.rpc.contracts.call. The API does have pass-through support for both old and new variants via the Contract interface, however it means the structure has changed to accommodate the new Substrate structure. Refer to the docs for the latest interface (including isSuccess/isError -> isOk/isErr, and the availability of the gasConsumed)

Contributed:

• Dedup similar types on generation (Thanks to https://github.com/monitz87)

Changes:

• Contract execution will now return contract events decoded in the result
• Add .dryRun on extrinsics (alongside .paymentInfo usage)
• Add system_syncState and syncstate_genSyncSpec RPCs
• Enhance error reporting, Call indicates explicit call as found
• Adjust internal metadata decoration and use as exposed from @types/metadata
• Expand Rococo known types to cater for v1 (specVersion 10)
• registry.hash now returns an H256 object (as opposed to raw Uint8Array)
• Use utility logger in all relevant error messages (consistency in logging)
• Add derive.council.proposal(<hash>) for retrieval of a single (expanded) proposal
• Correctly and transparently format type generation types (allowing for nested variants)
