connection-string

ADO.net and JDBC connection string parsing in Rust and JavaScript

Installation for Rust

$ cargo add connection-string

Usage for JavaScript

The crate is available in npm as @pimeys/connection-string. Usage patters try to follow the Rust version as close as possible. Please see the Rust docs for more information.

JDBC:

const j = new JdbcString("jdbc:sqlserver://localhost\\INSTANCE:1433;database=master;user=SA;password={my_password;123}");

console.log(j.server_name()); // "localhost"
console.log(j.port()); // 1433
console.log(j.instance_name()); // "INSTANCE"
console.log(j.get("database")); // "master"
console.log(j.get("password")); // "my_password;123" (see escaping)
console.log(j.keys()); // ["database", "user", "password"]
console.log(j.set("password", "a;;new;;password")); // "my_password;123" (returns the old value, if available)

// "jdbc:sqlserver://localhost\INSTANCE:1433;user=SA;database=master;password=a{;;}new{;;}password"
console.log(j.to_string())

ADO.net:

const a = new AdoNetString("server=tcp:localhost,1433;user=SA;password=a{;;}new{;;}password");

console.log(a.get("password")); // a;;new;;password
console.log(a.set("user", "john")); // "SA" (returns the old value, if available)

// "server=tcp:localhost,1433;user=john;password=a{;;}new{;;}password"
console.log(j.to_string())

Safety

This crate uses #![deny(unsafe_code)] to ensure everything is implemented in 100% Safe Rust.

Contributing

Want to join us? Check out our "Contributing" guide and take a look at some of these issues:

Building

The build procedure and dependencies are defined in the provided flake.nix file. Please install the unstable Nix with flakes support (Linux, macOS).

The WASM module can be built with:

nix build

This creates a link result to the current directory, containing a NodeJS package with the Rust code compiled as WASM bytecode.

Testing

Run the tests with the nix subcommand:

nix run .#test

Publishing

The updatePackageVersion command changes the package version to the Rust Cargo.toml and JavaScript package.json at the same time:

nix run .#updatePackageVersion 0.1.14

Don't forget to add the tag before publishing the library:

git tag v0.1.14

The publishing can be done separately or together with the publish command:

nix run .#publishRust
nix run .#publishJavascript

or

nix run .#publish

Please be sure you have the corresponding publishing rights in crates and npmjs.
