# BonsaiDb Client
Networked client for `bonsaidb-server`.
This crate supports two methods for accessing a BonsaiDb server: QUIC and
WebSockets.
QUIC is a new protocol built atop UDP. It is designed to operate more
reliably than TCP, and features TLS built-in at the protocol level.
WebSockets are an established protocol built atop TCP and HTTP.
[`Client`](https://docs.rs/bonsaidb-client/*/bonsaidb_client/struct.Client.html) provides access to BonsaiDb by implementing the
[`StorageConnection`](https://docs.rs/bonsaidb-core/*/bonsaidb_core/connection/trait.StorageConnection.html) trait.
## Minimum Supported Rust Version (MSRV)
While this project is alpha, we are actively adopting the current version of
Rust. The current minimum version is `1.58`, and we plan on updating the MSRV to
implement [namespaced
Features](https://github.com/khonsulabs/bonsaidb/issues/178) as soon as the
feature is released.
## WASM Support
This crate supports compiling to WebAssembly. When using WebAssembly, the
only protocol available is WebSockets.
### Testing Websockets in a Browser
We have a fully deployed [example
application](https://github.com/khonsulabs/minority-game) available that can be
downloaded and run locally. This example is confirmed to work using Firefox on a
local machine, or any modern browser when accessing
[https://minority-game.gooey.rs/](https://minority-game.gooey.rs/).
- Ensure that the browser is able to talk to the IP/port that you're bound to.
Browsers try to prevent malicious scripts. You may need to bind `0.0.0.0`
instead of `localhost`, for example, to circumvent these protections.
- All Chrome-based browsers [require secure
websockets](https://stackoverflow.com/a/50861413/457) over localhost. This
makes Chrome not a great candidate for testing WASM applications locally, as
installing a valid certificate in a test/dev environment can be tricky and/or
annoying.
## Feature Flags
By default, the `full` feature is enabled. These features are prefixed by
`client-` when being enabled from the omnibus `bonsaidb` crate.
- `full`: Enables `trusted-dns` and `websockets`
- `trusted-dns`: Enables using trust-dns for DNS resolution. If not
enabled, all DNS resolution is done with the OS's default name resolver.
- `websockets`: Enables `WebSocket` support for `bonsaidb-client`.
- `password-hashing`: Enables the ability to use password authentication
using Argon2.
- `tracing`: Enables `tracing` annotations on some functions and dependencies.
