说明： 一款非常优秀的js 调用frappe的js sdk。

Frappe Framework TypeScript/JavaScript库.

功能

支持的功能点:

• 🔐 授权： 用户名密码登录 (基于cookie) 以及 基于 token
• 🗄 数据库交互- Get document, get list of documents, get count, create, update and delete documents
• 📄 文件上传
• 🤙🏻 API调用

We plan to add the following features in the future:

• Support for common functions like exists in the database.

The library uses Axios under the hood to make API calls to your Frappe backend.

Installation

npm install frappe-js-sdk

or

yarn add frappe-js-sdk

Initialising the library

To get started, initialise the library:

import { FrappeApp } from 'frappe-js-sdk';
//Add your Frappe backend's URL
const frappe = new FrappeApp('https://test.frappe.cloud');

In case you want to use the library with token based authentication (OAuth bearer tokens or API key/secret pairs), you can initialise the library like this:

import { FrappeApp } from "frappe-js-sdk";

const frappe = new FrappeApp("https://test.frappe.cloud", {
    useToken: true,
    // Pass a custom function that returns the token as a string - this could be fetched from LocalStorage or auth providers like Firebase, Auth0 etc.
    token: getTokenFromLocalStorage(),
    // This can be "Bearer" or "token"
    type: "Bearer"
})

Authentication

Initialise the auth library

const auth = frappe.auth()

Login a user:

This makes an API call to the /api/method/login endpoint.

auth
  .loginWithUsernamePassword({ username: 'admin', password: 'my-password' })
  .then((response) => console.log('Logged in'))
  .catch((error) => console.error(error));

Get currently logged in user:

This makes an API call to the /api/method/frappe.auth.get_logged_user endpoint.

auth
  .getLoggedInUser()
  .then((user) => console.log(`User ${user} is logged in.`))
  .catch((error) => console.error(error));

Logout:

This makes an API call to the /api/method/logout endpoint.

auth
  .logout()
  .then(() => console.log('Logged out.'))
  .catch((error) => console.error(error));

Forget Password

This makes an API sends a password reset link to the specified email address.

auth
  .forgetPassword('[email protected]')
  .then(() => console.log('Password Reset Email Sent!'))
  .catch(() => console.error("We couldn't find your account."));

Database

Initialise the database library

const db = frappe.db();

Fetch document using document name

db.getDoc('DocType', 'My DocType Name')
  .then((doc) => console.log(doc))
  .catch((error) => console.error(error));

Fetch list of documents

db.getDocList('DocType')
  .then((docs) => console.log(docs))
  .catch((error) => console.error(error));

Optionally, a second argument can be provided to filter, sort, limit and paginate results.

db.getDocList('DocType', {
  /** Fields to be fetched */
  fields: ['name', 'creation'],
  /** Filters to be applied - SQL AND operation */
  filters: [['creation', '>', '2021-10-09']],
  /** Filters to be applied - SQL OR operation */
  orFilters: [],
  /** Fetch from nth document in filtered and sorted list. Used for pagination  */
  limit_start: 5,
  /** Number of documents to be fetched. Default is 20  */
  limit: 10,
  /** Sort results by field and order  */
  orderBy: {
    field: 'creation',
    order: 'desc',
  },
  /** Group the results by particular field */
  groupBy: 'name',
  /** Fetch documents as a dictionary */
  asDict: false,
})
  .then((docs) => console.log(docs))
  .catch((error) => console.error(error));

Type declarations are available for the second argument in the source code.

Fetch number of documents with filters

const filters = [['creation', '>', '2021-10-09']];
const useCache = true; /** Default is false - Optional **/
const debug = false; /** Default is false - Optional **/

db.getCount('DocType', filters, cache, debug)
  .then((count) => console.log(count))
  .catch((error) => console.error(error));

Create a document

To create a new document, pass the name of the DocType and the fields to createDoc.

db.createDoc('My Custom DocType', {
  name: 'Test',
  test_field: 'This is a test field',
})
  .then((doc) => console.log(doc))
  .catch((error) => console.error(error));

Update a document

To update an existing document, pass the name of the DocType, name of the document and the fields to be updated to updateDoc.

db.updateDoc('My Custom DocType', 'Test', {
  test_field: 'This is an updated test field.',
})
  .then((doc) => console.log(doc))
  .catch((error) => console.error(error));

Delete a document

To create a new document, pass the name of the DocType and the name of the document to be deleted to deleteDoc.

db.deleteDoc('My Custom DocType', 'Test')
  .then((response) => console.log(response.message)) // Message will be "ok"
  .catch((error) => console.error(error));

Usage with Typescript

The library supports Typescript out of the box. For example, to enforce type on the updateDoc method:

interface TestDoc {
  test_field: string;
}
db.updateDoc<TestDoc>('My Custom DocType', 'Test', {
  test_field: 'This is an updated test field.',
});

The library also has an inbuilt type FrappeDoc which adds the following fields to your type declarations when you use it with the database methods:

export type FrappeDoc<T> = T & {
  /** User who created the document */
  owner: string;
  /** Date and time when the document was created - ISO format */
  creation: string;
  /** Date and time when the document was last modified - ISO format */
  modified: string;
  /** User who last modified the document */
  modified_by: string;
  idx: number;
  /** 0 - Saved, 1 - Submitted, 2 - Cancelled */
  docstatus: 0 | 1 | 2;
  parent?: any;
  parentfield?: any;
  parenttype?: any;
  /** The primary key of the DocType table */
  name: string;
};

All document responses are returned as an intersection of FrappeDoc and the specified type.

API Calls

Initialise the call library

const call = frappe.call();

Make sure all endpoints are whitelisted (@frappe.whitelist()) in your backend

GET request

Make a GET request to your endpoint with parameters.

const searchParams = {
  doctype: 'Currency',
  txt: 'IN',
};
call
  .get('frappe.desk.search_link', searchParams)
  .then((result) => console.log(result))
  .catch((error) => console.error(error));

POST request

Make a POST request to your endpoint with parameters.

const updatedFields = {
  doctype: 'User',
  name: 'Administrator',
  fieldname: 'interest',
  value: 'Frappe Framework, ERPNext',
};
call
  .post('frappe.client.set_value', updatedFields)
  .then((result) => console.log(result))
  .catch((error) => console.error(error));

PUT request

Make a PUT request to your endpoint with parameters.

const updatedFields = {
  doctype: 'User',
  name: 'Administrator',
  fieldname: 'interest',
  value: 'Frappe Framework, ERPNext',
};
call
  .put('frappe.client.set_value', updatedFields)
  .then((result) => console.log(result))
  .catch((error) => console.error(error));

DELETE request

Make a DELETE request to your endpoint with parameters.

const documentToBeDeleted = {
  doctype: 'Tag',
  name: 'Random Tag',
};
call
  .put('frappe.client.delete', documentToBeDeleted)
  .then((result) => console.log(result))
  .catch((error) => console.error(error));

File Uploads

Initialise the file library

const file = frappe.file();

Upload a file with on progress callback

const myFile; //Your File object

const fileArgs = {
  /** If the file access is private then set to TRUE (optional) */
  "isPrivate": true,
  /** Folder the file exists in (optional) */
  "folder": "Home",
  /** File URL (optional) */
  "file_url": "",
  /** Doctype associated with the file (optional) */
  "doctype": "User",
  /** Docname associated with the file (mandatory if doctype is present) */
  "docname": "Administrator",
  /** Field in the document **/
  "fieldname": "image"
}

file.uploadFile(
            myFile,
            fileArgs,
            /** Progress Indicator callback function **/
            (completedBytes, totalBytes) => console.log(Math.round((completedBytes / totalBytes) * 100), " completed")
        )
        .then(() => console.log("File Upload complete"))
        .catch(e => console.error(e))
