# nice-grpc-common [![npm version][npm-image]][npm-url]

Common data structures and types for
[`nice-grpc`](https://github.com/deeplay-io/nice-grpc) and `nice-grpc-web`.

If you are making a middleware library, consider depending on
`nice-grpc-common`, as it is considered more stable in terms of semver. Also,
this allows you to build an isomorphic client middleware (working on both
Node.js and the Browser).

For application code, use `nice-grpc` or `nice-grpc-web` directly. Both
re-export names from `nice-grpc-common`.

npm install nice-grpc-common
