# Node/Electron Client SDK for OpenIM 👨💻💬

# Electron Client SDK for OpenIM 👨💻💬

|

Use this SDK to add instant messaging capabilities to your application. By connecting to a self-hosted [OpenIM](https://www.openim.online/) server, you can quickly integrate instant messaging capabilities into your app with just a few lines of code.
|
||||
|
||||
The underlying SDK core is implemented in [OpenIM SDK Core](https://github.com/openimsdk/openim-sdk-core). Using the [WebAssembly](https://webassembly.org/) support provided by Go language, it can be compiled into wasm for web integration. The web interacts with the [OpenIM SDK Core](https://github.com/openimsdk/openim-sdk-core) through JSON, and the SDK exposes a re-encapsulated API for easy usage. In terms of data storage, JavaScript handles the logic of the SQL layer by virtualizing SQLite and storing it in IndexedDB using [sql.js](https://sql.js.org/).

The underlying SDK core is implemented in [OpenIM SDK Core](https://github.com/openimsdk/openim-sdk-core). Using cgo, it is exported as C interfaces and provided as dynamic libraries such as DLL, SO, and DYLIB for use by other languages, implemented in [OpenIM SDK Cpp](https://github.com/openimsdk/openim-sdk-cpp.git).The web interacts with the [OpenIM SDK Cpp](https://github.com/openimsdk/openim-sdk-cpp.git) through JSON, using FFI (Foreign Function Interface) to communicate with the C interfaces, and the SDK exposes a re-encapsulated API for easy usage. For data storage, it utilizes the SQLite layer that is provided internally by the [OpenIM SDK Core](https://github.com/openimsdk/openim-sdk-core).

## Installation 💻
|
||||
|
||||
### Adding Dependencies
|
||||
|
||||
```shell
|
||||
npm install open-im-sdk-node --save
|
||||
npm install open-im-sdk-wasm @openim/electron-client-sdk --save
|
||||
```
|
||||
|
||||
### Obtaining Required Static Resources for WASM
|
||||
|
||||
Follow these steps to obtain the static resources required for WebAssembly (WASM):
|
||||
|
||||
1. Locate the `open-im-sdk-wasm` subdirectory in the `node_modules` directory of your project. Copy all the files in the `assets` folder to your project's public resource directory.
|
||||
|
||||
The files to be copied are:
|
||||
|
||||
- `openIM.wasm`
|
||||
- `sql-wasm.wasm`
|
||||
- `wasm_exec.js`
|
||||
|
||||
2. After copying the files, import the `wasm_exec.js` file in your `index.html` file using a `<script>` tag.
|
||||

||||

||||
## Usage 🚀
|
||||
|
||||
The following examples demonstrate how to use the SDK. TypeScript is used, providing complete type hints.
|
||||
|
||||
### Importing the SDK
|
||||
|
||||
```typescript
|
||||
import OpenIMSDK from 'open-im-sdk-node';
|
||||
## In main process
|
||||
|
||||
const OpenIM = new OpenIMSDK();
|
||||
```typescript
|
||||
import OpenIMSDKMain from '@openim/electron-client-sdk';
|
||||
|
||||
...
|
||||
new OpenIMSDKMain(libPath, mainWindow.webContents);
|
||||
...
|
||||
```
|
||||
|
||||
## In preload script
|
||||
|
||||
```typescript
|
||||
import '@openim/node-client-sdk/lib/preload';
|
||||
```
|
||||
|
||||
## In renderer process
|
||||
|
||||
```typescript
|
||||
import { getWithRenderProcess } from '@openim/node-client-sdk/lib/render';
|
||||
|
||||
const { instance } = getWithRenderProcess();
|
