CouchDB library for Rust

Crates.io docs.rs Build License dependency status Downloads


Here: http://docs.rs/couch_rs


Include this dependency in the Cargo.toml file:

couch_rs = "0.9"


This crate is an interface to CouchDB HTTP REST API. Works with stable Rust.

This library is a spin-off based on the excellent work done by Mathieu Amiot and others at Yellow Innovation on the Sofa library. The original project can be found at https://github.com/YellowInnovation/sofa

The Sofa library lacked support for async I/O, and missed a few essential operations we needed in our projects. That's why I've decided to create a new project based on the original Sofa code.

The rust-rs library has been updated to the Rust 2018 edition standards, uses async I/O, and compiles against the latest serde and reqwest libraries.

NOT 1.0 YET, so expect changes

Supports CouchDB 2.3.0 and up. Used in production with various CouchDB versions, including 3.2.2.

Be sure to check CouchDB's Documentation in detail to see what's possible.


A typical find operation looks like this:

use couch_rs::types::find::FindQuery;
use std::error::Error;
use serde_json::Value;
use couch_rs::document::DocumentCollection;

const DB_HOST: &str = "http://localhost:5984";
const TEST_DB: &str = "test_db";

async fn main() -> Result<(), Box<dyn Error>> {
  let client = couch_rs::Client::new(DB_HOST, "admin", "password")?;
  let db = client.db(TEST_DB).await?;
  let find_all = FindQuery::find_all();
  let docs = db.find_raw(&find_all).await?;


You can launch the included example with:

cargo run --example basic_operations

Running tests

Make sure that you have an instance of CouchDB 2.0+ running, either via the supplied docker-compose.yml file or by yourself. It must be listening on the default port. Since Couch 3.0 the "Admin Party" mode is no longer supported. This means you need to provide a username and password during launch. The tests and examples assume an "admin" CouchDB user with a "password" CouchDB password. Docker run command:

docker run --rm -p 5984:5984 -e COUCHDB_USER=admin -e COUCHDB_PASSWORD=password couchdb:3

And then cargo test --features=integration-tests -- --test-threads=1

Single-threading the tests is very important because we need to make sure that the basic features are working before actually testing features on dbs/documents.

If bash is available on your environment, you can also use the test.sh script which basically does the same thing described above.
