## Demo Installation

casibase uses Casdoor to manage members. So you need to create an organization and an application for casibase in a Casdoor instance.

### Casdoor configuration 

```shell
git clone https://github.com/casdoor/casdoor.git
```

refer to: https://casdoor.org/docs/basic/server-installation

Follow these steps to setup Casdoor for casibase:

- Create an **Organization**![1-Add-organization](assets/1-Add-organization.png)

- Configure information about the **Organization**![2-Configure-information-organization](assets/2-Configure-information-organization.png)

- Add a member to a newly created organization![3-Check-user](assets/3-Check-user.png)![4-Add-member-to-organization](assets/4-Add-member-to-organization.png)

- Configure member information (remember its **Name** as well as **Password**)![5-Configure-new-user](assets/5-Configure-new-user.png)



- Create a new **Application**![6-Add-application](assets/6-Add-application.png)

- Configuring **Application** Information (Remember **Name, ClientID** and **ClientSecret**. Change **RedirectURLs** to http://localhost:14000/callback) ![7-Configure-new-application](assets/7-Configure-new-application.png)

### casibase configuration 

#### Get the code

```shell
git clone https://github.com/casbin/casibase.git
```

#### Setup database

casibase will store its users, nodes and topics informations in a MySQL database named: `casibase`, will create it if not existed. The DB connection string can be specified at: https://github.com/casbin/casibase/blob/master/conf/app.conf

```ini
dataSourceName = root:123@tcp(localhost:3306)/
```

Casnode uses XORM to connect to DB, so all DBs supported by XORM can also be used.

#### Custom config

- #### Backend (`casibase\conf\app.conf`)

  ```ini
  casdoorEndpoint =  <Your_Casdoor_endpoint>
  clientId = <Your_clientId_in_Casdoor_configuration>
  clientSecret = <Your_clientSecret_in_Casdoor_configuration>
  casdoorOrganization = "casibase"
  casdoorApplication = "app-casibase"
  ```

- #### Frontend (`casibase\web\src\Conf.js`)

  ```ini
  export const AuthConfig = {
    ......
    clientId: <Your_clientId_in_Casdoor_configuration>,
    ......
  };
  ```

#### Run casnode

  - #### Backend (`casibase`)

    ```shell
    go run main.go
    ```

  - #### Frontend (`casibase\web`)

    ```shell
    yarn install
    yarn start
    ```

The **casibase** demo is shown above, and in the future users can upload various **knowledge** files, **wordsets**, and **factorsets** to achieve a **customized domain knowledge base**.
