Kantan CMS Library

Official TypeScript library for the Kantan CMS API. Supports both browser and Node.js environments.

Installation

npm install kantan-cms

Import Options

This library provides separate entry points for different environments:

Browser/Client-Side

The client export provides browser-safe form utilities without Node.js dependencies:

import { getFormToken, submitForm } from "kantan-cms/client";

// Get form token
const { token } = await getFormToken("collection-id");

// Submit form data
await submitForm("collection-id", {
  token,
  data: {
    name: "John Doe",
    email: "[email protected]"
  }
});

Note: For full API access (collections, records, schemas, etc.) in the browser, use your server as a proxy or use the server version in a Node.js environment.

Server-Side (Node.js with Caching)

Use the full-featured client with file system caching support:

import { KantanCms } from "kantan-cms/server";

const kantan = new KantanCms({
  apiKey: "your-api-key",
  projectId: "your-project-id",
  baseUrl: "https://api.kantan-cms.com", // optional
  useCache: true, // Enable caching (Node.js only)
  cachePath: "/tmp/my-cache", // Optional cache directory
  clearCacheAtInit: true // Optional: clear cache on initialization
});

Default Import (Node.js with Caching)

The default import uses the server version:

import { KantanCms } from "kantan-cms";

const kantan = new KantanCms({
  apiKey: "your-api-key",
  projectId: "your-project-id"
});

// List all collections
const { collections } = await kantan.getCollections({
  pageSize: 10,
  pageNum: 1
});

console.log(collections);

Authentication

You need two credentials to use the Kantan CMS API:

1. API Key - Your authentication key
2. Project ID - Your project identifier

Both are passed via HTTP headers (X-API-Key and X-Project-Id) and are automatically added by the library.

API Reference

Collections

List Collections

Get a paginated list of collections in your project.

const response = await kantan.listCollections({
  pageSize: 10,    // optional, default: 10
  pageNum: 1,      // optional, default: 1
  resp: "minimal"  // optional
});

// Or use the alias
const response = await kantan.getCollections({ pageSize: 20 });

Count Collections

Get the total number of collections.

const { count } = await kantan.countCollections();
console.log(`Total collections: ${count}`);

Get Collection

Get a specific collection by ID.

const { collection } = await kantan.getCollection("collection-uuid");
console.log(collection.name, collection.type);

Records

List Records

Get all records in a collection with pagination.

const { records } = await kantan.listRecords("collection-uuid", {
  pageSize: 20,
  pageNum: 1
});

records.forEach(record => {
  console.log(record.id, record);
});

Get Record

Get a specific record by ID.

const { records } = await kantan.getRecord(
  "collection-uuid",
  "record-uuid"
);

console.log(records[0]);

Count Records

Get the total number of records in a collection.

const { count } = await kantan.countRecords("collection-uuid");
console.log(`Total records: ${count}`);

Schemas

Get Schema Type

Get the schema type structure for a collection. Returns a mapping of custom field keys to their respective types.

const { schema_item } = await kantan.getSchemaType("collection-uuid");

// Example output: { "title": "string", "price": "number", "published": "boolean" }
console.log(schema_item);

Forms

Get Form Token

Get a form submission token for a specific collection.

const { token } = await kantan.getFormToken("collection-uuid");
console.log(`Form token: ${token}`);

Submit Form

Submit data to a form-type collection.

const result = await kantan.submitForm("collection-uuid", {
  data: {
    name: "John Doe",
    email: "[email protected]",
    message: "Hello from the API!"
  },
  token: "your-form-token" // obtained from getFormToken()
});

API Key Validation

Validate API Key

Check if your API key is valid.

const { status } = await kantan.validateApiKey();

if (status === 200) {
  console.log("API key is valid!");
}

Hosting

Generate Presigned URL

Generate a presigned URL for uploading a zip file for hosting.

const { presigned_zip } = await kantan.generatePresignedUrl();
console.log(`Upload URL: ${presigned_zip.url}`);

Update Hosting Status

Update the hosting status for your project.

await kantan.updateHostingStatus({
  hosting: {
    status: "host_complete",
    status_message: "Deployment successful"
  }
});

Available hosting statuses:

• host_error
• preview_error
• host_complete
• preview_complete
• waiting
• running
• error

TypeScript Support

This library is written in TypeScript and includes full type definitions. All API responses are fully typed.

import {
  KantanCms,
  Collection,
  Record,
  CollectionType,
  HostingStatus
} from "kantan-cms";

const kantan = new KantanCms({
  apiKey: process.env.KANTAN_API_KEY!,
  projectId: process.env.KANTAN_PROJECT_ID!
});

// Full type inference
const { collections } = await kantan.getCollections();
collections.forEach((collection: Collection) => {
  console.log(collection.name);
});

Error Handling

The library throws KantanCmsError for API errors.

import { KantanCms, KantanCmsError } from "kantan-cms";

try {
  const { collection } = await kantan.getCollection("invalid-uuid");
} catch (error) {
  if (error instanceof KantanCmsError) {
    console.error(`API Error (${error.statusCode}): ${error.message}`);
    console.error("Response:", error.response);
  } else {
    console.error("Unexpected error:", error);
  }
}

Advanced Usage

Custom Base URL

If you're using a custom deployment or proxy:

const kantan = new KantanCms({
  apiKey: "your-api-key",
  projectId: "your-project-id",
  baseUrl: "https://custom-api.example.com"
});

Environment Support

Browser Usage

The /client export provides form utilities that work in browsers without Node.js dependencies:

// ✅ Browser-safe form functions
import { getFormToken, submitForm } from "kantan-cms/client";

The client version:

• ✅ No Node.js dependencies (no fs, path, etc.)
• ✅ Smaller bundle size
• ✅ Works in all modern browsers
• ✅ Perfect for form submissions
• ❌ No full API access (use server as proxy for collections, records, etc.)

Node.js Usage

For full API access, use the server version:

// ✅ Full API with caching
import { KantanCms } from "kantan-cms/server";

// ✅ Or the default import (same as server)
import { KantanCms } from "kantan-cms";

The server version includes:

• ✅ Full API access (collections, records, schemas, hosting, etc.)
• ✅ File system caching support
• ✅ Cache management methods
• ✅ Form functions

Framework-Specific Examples

Next.js

Server-side API Route:

// app/api/collections/route.ts
import { KantanCms } from "kantan-cms/server";

export async function GET() {
  const kantan = new KantanCms({
    apiKey: process.env.KANTAN_API_KEY!,
    projectId: process.env.KANTAN_PROJECT_ID!,
    useCache: true
  });

  const { collections } = await kantan.getCollections();
  return Response.json({ collections });
}

Client-side Form:

// app/contact/page.tsx
"use client"
import { getFormToken, submitForm } from "kantan-cms/client";
import { useState } from "react";

export default function ContactPage() {
  const [submitted, setSubmitted] = useState(false);

  async function handleSubmit(e: React.FormEvent<HTMLFormElement>) {
    e.preventDefault();
    const formData = new FormData(e.currentTarget);

    const { token } = await getFormToken("form-collection-id");

    await submitForm("form-collection-id", {
      token,
      data: {
        name: formData.get("name"),
        email: formData.get("email"),
        message: formData.get("message")
      }
    });

    setSubmitted(true);
  }

  return (
    <form onSubmit={handleSubmit}>
      {/* form fields */}
    </form>
  );
}

React (Vite/CRA)

// src/components/ContactForm.tsx
import { getFormToken, submitForm } from "kantan-cms/client";

export function ContactForm() {
  async function handleSubmit(e: React.FormEvent) {
    e.preventDefault();

    const { token } = await getFormToken("form-collection-id");

    await submitForm("form-collection-id", {
      token,
      data: { /* form data */ }
    });
  }

  return <form onSubmit={handleSubmit}>{/* ... */}</form>;
}

Pagination Helper

Example of paginating through all records:

async function getAllRecords(collectionId: string) {
  const allRecords = [];
  let pageNum = 1;
  const pageSize = 100;

  while (true) {
    const { records } = await kantan.listRecords(collectionId, {
      pageSize,
      pageNum
    });

    if (records.length === 0) break;

    allRecords.push(...records);
    pageNum++;

    if (records.length < pageSize) break; // Last page
  }

  return allRecords;
}

Collection Types

Collections in Kantan CMS can be one of the following types:

• custom - Custom content collections
• blog - Blog post collections
• media - Media asset collections
• form - Form submission collections
• dict - Dictionary/key-value collections

Requirements

• Node.js >= 18.0.0
• Modern browsers with fetch API support

CommonJS vs ESM

This library supports both CommonJS and ES Modules:

// ESM
import { KantanCms } from "kantan-cms";

// CommonJS
const { KantanCms } = require("kantan-cms");

Examples

Blog Integration

// Get all blog posts
const { records: posts } = await kantan.listRecords("blog-collection-id", {
  pageSize: 50
});

posts.forEach(post => {
  console.log(`${post.title} - ${post.created_at}`);
});

Form Submission Flow

// 1. Get form token
const { token } = await kantan.getFormToken("form-collection-id");

// 2. Submit form data
await kantan.submitForm("form-collection-id", {
  token,
  data: {
    fullName: "Jane Smith",
    email: "[email protected]",
    inquiry: "Product question"
  }
});

Media Gallery

// Get media collection
const { records: mediaItems } = await kantan.listRecords("media-collection-id");

mediaItems.forEach(item => {
  console.log(`${item.filename}: ${item.url}`);
});
