Here's a professional and well-structured README.md for your Payload SDK:

Payload SDK

A fully type-safe SDK for interacting with the Payload CMS REST API. This package simplifies working with Payload by offering a seamless, strongly typed developer experience—closely mirroring the Local API interface.

✨ Features

• 🔒 Full Type Safety – powered by your generated Payload types.
• 🔁 Support for all core operations – including collections, globals, auth, versions, and file uploads.
• 🔍 Query filters & population – type-safe where, select, and populate support.
• 📁 File uploads – simplified with native Blob, File, or URL input.
• 🧩 Custom endpoints – easy access to non-standard REST routes.
• ⚙️ Custom fetch and request config – extend or replace fetch logic and share common options.

🚀 Installation

npm install @payloadcms/sdk
# or
pnpm add @payloadcms/sdk

🛠️ Usage

import { PayloadSDK } from "@payloadcms/sdk";
import type { Config } from "./payload-types";

const sdk = new PayloadSDK<Config>({
    baseURL: "https://example.com/api",
});

✅ Core Operations

Find Documents

const posts = await sdk.find({
    collection: "posts",
    draft: true,
    limit: 10,
    locale: "en",
    page: 1,
    where: { _status: { equals: "published" } },
});

Find by ID

const post = await sdk.findByID({
    collection: "posts",
    id,
    draft: true,
    locale: "en",
});

Count Documents

const result = await sdk.count({
    collection: "posts",
    where: { id: { equals: post.id } },
});

Create Document

const result = await sdk.create({
    collection: "posts",
    data: { text: "hello" },
});

Create with File Upload

const result = await sdk.create({
    collection: "media",
    file, // File | Blob | string (URL)
    data: {},
});

Update Document by ID

const result = await sdk.update({
    collection: "posts",
    id: post.id,
    data: { text: "updated" },
});

Bulk Update

const result = await sdk.update({
    collection: "posts",
    where: { id: { equals: post.id } },
    data: { text: "bulk-updated" },
});

Delete by ID

const result = await sdk.delete({
    collection: "posts",
    id: post.id,
});

Bulk Delete

const result = await sdk.delete({
    collection: "posts",
    where: { id: { equals: post.id } },
});

🌐 Global Operations

await sdk.findGlobal({ slug: "global" });
await sdk.updateGlobal({ slug: "global", data: { text: "updated" } });

🔐 Auth Operations

// Login
await sdk.login({
    collection: "users",
    data: { email: "[email protected]", password: "123456" },
});

// Me
await sdk.me(
    { collection: "users" },
    {
        headers: { Authorization: `JWT ${token}` },
    }
);

// Refresh Token
await sdk.refreshToken(
    { collection: "users" },
    {
        headers: { Authorization: `JWT ${token}` },
    }
);

// Forgot Password
await sdk.forgotPassword({
    collection: "users",
    data: { email: "[email protected]" },
});

// Reset Password
await sdk.resetPassword({
    collection: "users",
    data: { token, password: "new-password" },
});

🕓 Versions

await sdk.findVersions({
    collection: "posts",
    where: { parent: { equals: post.id } },
});

await sdk.findVersionByID({
    collection: "posts",
    id: version.id,
});

await sdk.restoreVersion({
    collection: "posts",
    id,
});

// Global Versions
await sdk.findGlobalVersions({ slug: "global" });
await sdk.findGlobalVersionByID({ slug: "global", id: version.id });
await sdk.restoreGlobalVersion({ slug: "global", id });

🧩 Custom Requests

await sdk.request({
    method: "POST",
    path: "/send-data",
    json: { id: 1 },
});

⚙️ Custom Fetch + Shared Init

const sdk = new PayloadSDK<Config>({
    baseURL: "https://example.com/api",
    baseInit: {
        credentials: "include",
    },
    fetch: async (url, init) => {
        console.log("Request started");
        const response = await fetch(url, init);
        console.log("Request completed");
        return response;
    },
});

📘 Notes

• All operations support a third optional parameter to customize fetch options (headers, etc.).
• Fully compatible with RequestInit, enabling cookies, custom headers, CORS config, and more.
