10.0.0

Changed

• BREAKING: Rename the package from eth-json-rpc-middleware to @metamask/eth-json-rpc-middleware (#180)
• Change all middleware request and response types to unknown (#183)
  • This more accurately reflects the expectations of the middleware, and the way they had been used. This was required to more easily compose this middleware with others that had non-matching types.
• The block cache and the inflight cache middleware types have been updated to include the skipCache request property (#178)
  • This property was always supported, but it was missing from the type.

9.0.1

Changed

• Update @metamask/eth-sig-util from v3 to v5 (#133, #150)
• Remove unused dependencies (#133)

Fixed

• Fix block-ref middleware, and prevent it from making a duplicate request (#151)
• Fix retryOnEmpty middleware and prevent it from making duplicate requests (#147)

9.0.0

Added

• Add logging (#140)
  • 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-json-rpc-middleware:* or metamask:*.

Changed

• BREAKING: Require Node >= 14 (#137)

8.1.0

Added

• Expose SafeEventEmitterProvider type (#127)

Fixed

• Move eth-block-tracker from devDependencies to dependencies (#125)
  • We depend upon this package only for types.

8.0.2

Added

• Added suppressUnauthorized param to getAccounts (#116)

Security

• Bump node-fetch to resolve vulnerability (#115)

8.0.1

Fixed

• Restore support for query strings in fetch middleware (#109)
  • As of v7.0.0, query strings were silently dropped from RPC URLs passed in. Now they are preserved, as was the case in v6.0.0.

8.0.0

Added

• BREAKING: Add eth_signTransaction support (#96)
  • We consider this breaking because a wallet application may not support this method, and would have to explicitly block it until its implications can be adequately represented to the user.
• Add send method to provider and ethersProviderAsMiddleware (#97)

7.0.1

Fixed

• blockTrackerInspectorMiddleware (#88)
  • Due to an error introduced in #68, this middleware would sometimes hang indefinitely.

7.0.0

Added

• TypeScript types (#68)

Changed

• (BREAKING) Move middleware files to /src folder (#60)
• (BREAKING) Convert all exports to named (#81)
• Migrate to TypeScript (#68)
• Replace url dependency with native URL global (#67)
• Ask bundlers to ignore Node-specific depedencies in browser environments (#78, #84)
• Removed various unused production dependencies (#10, #80)

Fixed

• retryOnEmpty middleware error messages (#58)
  • They were referencing a different middleware.
• Default unrecognized methods to never be cached (#66)
• Only publish necessary files (#70)
• Robustify providerFromEngine callback parameter validation (#76)
  • Previously, it only errored if the parameter was falsy. Now, it will error if it is not a function.
  • Passing the previous implementation a truthy, non-function value would cause fatal downstream errors.
• Prevent caching unrecognized requests (#75)
  • Previously, nonsense values were sometimes cached, resulting in an ugly state and possibly a minor performance penalty.

Removed

• (BREAKING) Parity middleware (#63)
  • Previously imported as eth-json-rpc-middleware/wallet-parity.js
• (BREAKING) Scaffold middleware (#60)
  • This was just a re-export from json-rpc-engine.

v6.0.0

• Breaking: Delete VM middleware (#56)
  • Previously available for import via eth-json-rpc-middleware/vm.js
