### Testing with a pre-set token

Source: https://ilmar7786.github.io/marzban-sdk/docs/authentication/manual-auth

Create an SDK with a preset token for testing. The token is used immediately; authenticateOnInit is false to avoid an initial login.

```typescript
const sdk = await createMarzbanSDK({
  baseUrl: 'http://localhost:7777',
  username: 'test',
  password: 'test',
  token: 'test-jwt-token',
  authenticateOnInit: false,
})
```

--------------------------------

### Get admin usage

Source: https://ilmar7786.github.io/marzban-sdk/docs/modules/admins

Gets traffic usage attributed to a specific admin's users. Returns total bytes used as a number.

```typescript
const usage = await sdk.admin.getAdminUsage('operator', {
  start: '2024-01-01T00:00:00',
  end:   '2024-01-31T23:59:59',
})
```

--------------------------------

### Marzban service with webhook handlers

Source: https://ilmar7786.github.io/marzban-sdk/docs/webhooks/nestjs

Create the MarzbanService that initializes the SDK and registers webhook event handlers for user_created and user_limited events.

```typescript
// marzban/marzban.service.ts
import { Injectable, OnModuleInit } from '@nestjs/common'
import { createMarzbanSDK, MarzbanSDK } from 'marzban-sdk'

@Injectable()
export class MarzbanService implements OnModuleInit {
  sdk!: MarzbanSDK

  async onModuleInit() {
    this.sdk = await createMarzbanSDK({
      baseUrl: process.env.MARZBAN_URL!,
      username: process.env.MARZBAN_USER!,
      password: process.env.MARZBAN_PASS!,
      webhook: {
        secret: process.env.MARZBAN_WEBHOOK_SECRET,
      },
    })

    this.sdk.webhook.on('user_created', payload => {
      console.log('User created:', payload.user.username)
    })

    this.sdk.webhook.on('user_limited', payload => {
      console.log('User limited:', payload.username)
    })
  }
}
```

--------------------------------

### Example Conventional Commit messages

Source: https://ilmar7786.github.io/marzban-sdk/docs/resources/contributing

### Manage a local Marzban panel with pnpm local scripts

Source: https://ilmar7786.github.io/marzban-sdk/docs/resources/contributing

Starts a disposable local Marzban panel in Docker, follows its logs, stops it, or stops and wipes its data. Used for trying changes against a real panel and by the integration test suite.

```bash
pnpm local:up     # start
pnpm local:logs   # follow logs
pnpm local:down   # stop
pnpm local:reset  # stop and wipe data
```

--------------------------------

### Bootstrap standard templates on first run

Source: https://ilmar7786.github.io/marzban-sdk/docs/modules/user-templates

Checks if no templates exist, then creates two standard templates: 'Basic – 5GB / 30d' and 'Pro – Unlimited / 30d'. Uses parseSize to convert human-readable sizes.

```javascript
import { parseSize } from 'marzban-sdk'

const templates = await sdk.userTemplate.getUserTemplates()

if (templates.length === 0) {
  await sdk.userTemplate.addUserTemplate({
    name: 'Basic – 5GB / 30d',
    data_limit: parseSize('5GB'),
    expire_duration: 30 * 86400,
    inbounds: { vless: ['VLESS TCP REALITY'] },
  })

  await sdk.userTemplate.addUserTemplate({
    name: 'Pro – Unlimited / 30d',
    data_limit: 0,
    expire_duration: 30 * 86400,
    inbounds: {
      vless: ['VLESS TCP REALITY'],
      vmess: ['VMess Websocket'],
    },
  })
}
```

--------------------------------

### parseSize examples

Source: https://ilmar7786.github.io/marzban-sdk/docs/utilities/data-sizes

Examples of parsing human-readable size strings into bytes. Supports binary (1024-based) by default, with an option for decimal (SI) units. Invalid input returns 0.

```typescript
parseSize('10GB')          // 10737418240  (binary, 1024³)
parseSize('10 gb')         // 10737418240
parseSize('1.5 TB')        // 1649267441664
parseSize(1073741824)      // 1073741824   (number passthrough)
parseSize('500MB', { decimal: true }) // 500000000 (SI units, 1000³)
parseSize('invalid')       // 0
```

--------------------------------

### Route Handler for users API

Source: https://ilmar7786.github.io/marzban-sdk/docs/integrations/nextjs

Route Handler with GET and POST endpoints. GET fetches up to 50 users, POST creates a user from the request body and returns 201 on success.

```typescript
// app/api/users/route.ts
import { NextResponse } from 'next/server'
import { getSDK } from '@/lib/marzban'

export async function GET() {
  const sdk = await getSDK()
  const result = await sdk.user.getUsers({ limit: 50 })
  return NextResponse.json(result)
}

export async function POST(req: Request) {
  const sdk = await getSDK()
  const body = await req.json()
  const user = await sdk.user.addUser(body)
  return NextResponse.json(user, { status: 201 })
}
```

--------------------------------

### Connect with replay 'all' and 'skip' options

Source: https://ilmar7786.github.io/marzban-sdk/docs/realtime/replay

Shows two ways to call connectByCore with the replay option: 'all' delivers every line including duplicates, while 'skip' drops replayed messages until a clean one arrives. Both examples use the same onMessage callback that logs each message.

```javascript
// See every line, duplicates included
await sdk.logs.connectByCore({ onMessage: data => console.log(data), replay: 'all' })

// Drop every replayed message outright, until the first clean one
await sdk.logs.connectByCore({ onMessage: data => console.log(data), replay: 'skip' })
```

--------------------------------

```

--------------------------------

### Create MarzbanService that initializes SDK

Source: https://ilmar7786.github.io/marzban-sdk/docs/integrations/nestjs

Service that creates the MarzbanSDK instance on module init, reads configuration from ConfigService, and provides a getter for the SDK. It also destroys the SDK on module destroy.

```typescript
// marzban/marzban.service.ts
import { Injectable, OnModuleInit, OnModuleDestroy } from '@nestjs/common'
import { createMarzbanSDK, MarzbanSDK } from 'marzban-sdk'
import { ConfigService } from '@nestjs/config'

@Injectable()
export class MarzbanService implements OnModuleInit, OnModuleDestroy {
  private _sdk!: MarzbanSDK

  constructor(private config: ConfigService) {}

  async onModuleInit() {
    this._sdk = await createMarzbanSDK({
      baseUrl: this.config.getOrThrow('MARZBAN_URL'),
      username: this.config.getOrThrow('MARZBAN_USER'),
      password: this.config.getOrThrow('MARZBAN_PASS'),
      logger: {
        level: this.config.get('NODE_ENV') === 'production' ? 'error' : 'info',
      },
      webhook: {
        secret: this.config.get('MARZBAN_WEBHOOK_SECRET'),
      },
    })
  }

  async onModuleDestroy() {
    await this._sdk?.destroy()
  }

  get sdk(): MarzbanSDK {
    return this._sdk
  }
}
```

### Authentication Lifecycle Diagram

Source: https://ilmar7786.github.io/marzban-sdk/docs/authentication/auto-authentication

Shows the sequence of operations during SDK initialization and request handling, including token storage and retry logic on 401 responses.

```text
createMarzbanSDK()
  └─► validateConfig()
  └─► new MarzbanSDK()   ← interceptors wired
  └─► sdk.authorize()
        └─► POST /api/admin/token
        └─► token stored in memory
  └─► returns sdk

any sdk.user / sdk.node / ... call
  └─► request interceptor attaches Bearer token
  └─► response interceptor
        └─► 200 → return data
        └─► 401 → re-authenticate → retry once → return data
```

--------------------------------

import { createMarzbanSDK } from 'marzban-sdk'

const nestLogger = new NestLogger('MarzbanSDK')

const sdk = await createMarzbanSDK({
  // ...
  logger: {
    debug: (msg, ctx) => nestLogger.debug(msg, ctx),
    info:  (msg, ctx) => nestLogger.log(msg, ctx),
