Overview

pgz - postgres driver/connector written in Zig (status pre-alpha development)

Package manager ready

Add following lines to your build.zig.zon dependencies:

.pgz = .{
    .url = "git+https://github.com/star-tek-mb/pgz#master",
}

Run zig build then obtain hash of the package and insert it to build.zig.zon.

Then you can use it as a library. Add following lines to build.zig:

const pgz_dep = b.dependency("pgz", .{ .target = target, .optimize = optimize });

exe.addModule("pgz", pgz_dep.module("pgz"));

Example

const std = @import("std");
const Connection = @import("pgz").Connection;

pub fn main() !void {
    var dsn = try std.Uri.parse("postgres://testing:testing@localhost:5432/testing");
    var connection = try Connection.init(std.heap.page_allocator, dsn);
    defer connection.deinit();
    var result = try connection.query("SELECT 1 as number;", struct { number: ?[]const u8 });
    defer result.deinit();

    try connection.exec("CREATE TABLE users(name text not null);");
    defer connection.exec("DROP TABLE users;") catch {};
    var stmt = try connection.prepare("INSERT INTO users(name) VALUES($1);");
    defer stmt.deinit();
    try stmt.exec(.{"hello"});
    try stmt.exec(.{"world"});

    try std.io.getStdOut().writer().print("number = {s}\n", .{result.data[0].number.?});
}

TODOs

• Optimize allocations (use stack fallback allocator for messages)
• Fix all todos in code
• Connection pools (do we need them?)
• Complete and test in production?

Testing

Create user testing with password testing.

Create database testing.

Run zig build test
