eth-block-tracker - npm Package Versions

[8.1.0]

Changed

• Typescript: Add checkForLatestBlock function to BlockTracker interface (#184)

[8.0.0]

Changed

• Bump @metamask/utils from ^5.0.2 to ^8.1.0 (#178)
• BREAKING: Bump @metamask/eth-json-rpc-provider from ^1.0.0 to ^2.1.0 (#174)
• BREAKING: Increase minimum Node.js version to 16 (#173)

[7.1.0]

Added

• Add usePastBlocks to constructor (#151)
  • Optional flag. When set to true, it allows blocks less than the current block number to be cached and returned.

[7.0.1]

Changed

• Dependency updates:
  • Bump @metamask/utils from 5.0.1 to 5.0.2
    • #141
    • #144
  • Bump @metamask/safe-event-emitter from 2.0.0 to 3.0.0 (#143)

[7.0.0]

Changed

• BREAKING: The type of the provider option for PollingBlockTracker and SubscribeBlockTracker has changed (#130)
  • The provider option must be compatible with the SafeEventEmitterProvider type from @metamask/eth-json-rpc-middleware.
  • The new provider type should be mostly equivalent, except that it's now expected to have a send method. We don't use that send method in this package though.

Removed

• BREAKING: Remove the Provider exported type (#130)
  • We now use @metamask/eth-json-rpc-provider for this instead, so there was no need to re-export it.

[6.1.0]

Added

• Add back Provider type that was accidentally removed in 6.0.0 (#117)

Fixed

• Align Provider type with eth-json-rpc-middleware to prevent typecasting (#117)

[6.0.0]

Added

• Add logging (#112)
  • You will not be able to see log messages by default, but you can turn them on for this library by setting the DEBUG environment variable to metamask:eth-block-tracker:* or metamask:*.
• Add destroy method to block tracker classes (#106)
• Update PollingBlockTracker to support new blockResetDuration option (#103)
• Expose types that represent options to PollingBlockTracker and SubscribeBlockTracker constructors (#103)

Changed

• BREAKING: Require Node >= 14 (#113)
• BREAKING: Make BaseBlockTracker abstract (#103)
  • If you are using this class directly, you must only use PollingBlockTracker or SubscribeBlockTracker.
• BREAKING: Make options for BaseBlockTracker required (#103)
  • Subclasses must pass a set of options to super in their constructors.
• Make argument to removeAllListeners in BaseBlockTracker optional (#103)
• BREAKING: Update signatures for _start and _end in BaseBlockTracker (#103)
  • Subclasses must provide an implementation for both of these methods; they are no longer no-ops.
  • Both methods must return a promise.
• Update SubscribeBlockTracker to not pass empty newHeads parameter to eth_subscribe call (#108)
  • This change was made because OpenEthereum does not support this parameter. While we've done our best to confirm that this will not be a breaking change for other Ethereum implementations, you will want to confirm no breakages for yours.

Security

[4.4.3] - 2019-08-30

Added

Changed
