Frappe JS Client

Zero-dependency TypeScript/JavaScript client for Frappe Framework REST APIs. Uses globalThis.fetch.

Supports Frappe v14, v15, and v16. Default apiVersion is 2 (/api/v2, Frappe 15+). Pass { apiVersion: 1 } for classic /api/method + /api/resource — that is the v14-safe path, and it also works on v15 and v16.

Realtime is optional: frappe-js-client/realtime with peer socket.io-client. Core stays zero-dependency.

Installation

pnpm add frappe-js-client
# or
npm install frappe-js-client

No runtime dependencies.

Quick start

import { createFrappeClient, tokenAuth, consoleLogger } from 'frappe-js-client'

const frappe = createFrappeClient({
    url: 'https://frappe.example.com',
    auth: tokenAuth({ apiKey: '...', apiSecret: '...' }),
    logger: consoleLogger(), // optional; pathname only, no query/headers/bodies
})

const user = await frappe.db.getDoc('User', 'Administrator')

Session login (classic /api/method/login):

await frappe.auth.login({
    username: 'admin',
    password: 'password',
})

Extended modules (permission, workflow, report, desk, site):

import { withExtended } from 'frappe-js-client/extended'

const app = withExtended(frappe)
await app.workflow.apply(doc, 'Approve')

Realtime (optional peer socket.io-client):

import { createRealtime } from 'frappe-js-client/realtime'

const realtime = createRealtime(app)
realtime.subscribeDoc('ToDo', 'TD-1', (event) => console.log(event))

Development

Requires pnpm 11 and Node.js 20+ (CI uses Node 22).

This package lives in a pnpm workspace. Clone the repo root, not packages/client alone:

git clone https://github.com/dhiashalabi/frappe-js-client.git
cd frappe-js-client
pnpm install
pnpm test
pnpm lint
pnpm build
pnpm docs:start

Unit tests: pnpm test. Integration and browser tests require a separately managed Frappe site:

FRAPPE_TEST_URL=http://frappe14.localhost:8000 pnpm test:integration
FRAPPE_TEST_URL=http://frappe14.localhost:8000 pnpm test:browser

Live tests need a running site. Do not commit credentials (.env / .env.live are gitignored):

FRAPPE_LIVE_URL=http://127.0.0.1:8001 pnpm test:live

If the URL host is not the Frappe site name (for example 127.0.0.1 vs frappe16.localhost), pass siteName into createFrappeClient so requests send Host / X-Frappe-Site-Name.
