Type-safe HTTP client that mirrors moost-db controller endpoints. Works in browsers, Node.js, and any runtime with fetch. Each method maps 1:1 to a controller endpoint — filters, sorting, pagination, relation loading, text search, and aggregation are all supported through typed query controls.

In SSR environments, Moost's fetch automatically routes local requests to handlers in-process, so the same Client instance works on both server and browser.

Installation

pnpm add @atscript/db-client

Quick Start

import { Client } from "@atscript/db-client";
import type { User } from "./models/user.as";

const users = new Client<typeof User>("/api/users", {
  baseUrl: "https://api.example.com",
});

// Query                            → GET /query
const active = await users.query({ filter: { status: "active" } });

// Get one                          → GET /one/:id
const user = await users.one("abc-123");

// Insert                           → POST /
const { insertedId } = await users.insert({ name: "Alice" });

// Update                           → PATCH /
await users.update({ id: insertedId, role: "admin" });

// Remove                           → DELETE /:id
await users.remove(insertedId);

// Count                            → GET /query ($count)
const total = await users.count();

// Paginate                         → GET /pages
const page = await users.pages({ filter: { active: true } }, 1, 20);

// Metadata                         → GET /meta
const meta = await users.meta();

• Aggregation — typed $groupBy dimensions and measures with inferred result types
• Search — full-text and vector search via query controls
• Client-side validation — validates writes against the Atscript schema before sending
• Error handling — ClientError with structured validation errors
• Configurable — custom fetch, static or async headers, base URL
