# Vercel Integratie

> Monitor Vercel deployments en serverless functions

## Overview

Vercel is een platform voor frontend frameworks en static sites met serverless functions. De PulseGuard Vercel integratie stelt je in staat om je Vercel projecten, deployments en functions automatisch te monitoren, inclusief performance metrics, error tracking en deployment status.

<Note>
  Vercel integratie is beschikbaar vanaf de Expert plannen. Je hebt een Vercel account nodig met API toegang.
</Note>

* **Frontend Deployment**: Next.js, React, Vue.js, etc.
* **Serverless Functions**: API routes en serverless functions
* **Edge Functions**: Worldwide edge computing
* **Preview Deployments**: Per-branch deployments
* **Analytics**: Real-time performance metrics
* **Global CDN**: Worldwide content delivery

## Vercel Account Koppelen

<Steps>
  <Step title="Vercel Token Genereren">
    Ga naar **Vercel Dashboard** → **Settings** → **Tokens**
  </Step>

  <Step title="Nieuwe Token Aanmaken">
    Klik "Create Token" en geef een naam (bijv. "PulseGuard")
  </Step>

  <Step title="Token Scope Selecteren">
    Selecteer minimaal "Read" permissions voor je projecten
  </Step>

  <Step title="Token Opslaan">
    Kopieer de token onmiddellijk - deze zie je niet meer!
  </Step>

  <Step title="PulseGuard Configureren">
    Ga naar **Settings** → **Integrations** → **Vercel**
  </Step>

  <Step title="Account Koppelen">
    Voer je Vercel token in en klik "Connect"
  </Step>
</Steps>

## Token Permissions

De Vercel API token heeft de volgende permissies nodig:

```json theme={null}
{
  "scopes": [
    "read:project",
    "read:deployment",
    "read:team",
    "read:user"
  ]
}
```

**Minimale Permissions:**

* `read:project` - Voor project discovery en configuratie
* `read:deployment` - Voor deployment status en metrics
* `read:team` - Voor team-based project access
* `read:user` - Voor user account informatie

## Resource Discovery

Zodra je Vercel account gekoppeld is, scant PulseGuard automatisch:

### Discovery Proces

1. **Project Scanning**: Alle Vercel projecten worden geïdentificeerd
2. **Deployment Analysis**: Actieve deployments worden geanalyseerd
3. **Function Detection**: API routes en edge functions gevonden
4. **Domain Mapping**: Custom domains worden gekoppeld
5. **Service Creation**: PulseGuard services worden aangemaakt

### Resource Types

#### Production Deployments

* **HTTP Health Checks**: Homepage en API endpoints
* **Response Time Monitoring**: Performance tracking
* **SSL Certificate Checks**: Vercel SSL status
* **Uptime Monitoring**: 24/7 availability checks

#### Preview Deployments

* **Branch-based Monitoring**: Per Git branch monitoring
* **Pull Request Checks**: PR-based deployment monitoring
* **Temporary URLs**: Vercel preview URL monitoring

#### Serverless Functions

* **Function Execution**: Cold start en execution time monitoring
* **Error Rates**: Function failure rate tracking
* **Timeout Detection**: Function timeout alerts
* **Request Volume**: Function invocation frequency

#### Edge Functions

* **Global Performance**: Worldwide execution metrics
* **Latency Monitoring**: Edge-to-user latency
* **Error Tracking**: Global error rate monitoring
* **Geographic Distribution**: Performance per region

## Monitoring Configuratie

### Automatische Service Aanmaak

Voor elke ontdekte Vercel resource creëert PulseGuard:

1. **HTTP Service Monitors**: Voor websites en API endpoints
2. **Function Monitors**: Voor serverless function health
3. **Deployment Monitors**: Voor build en deployment status
4. **Domain Monitors**: Voor custom domain availability

### Protocol Configuratie

#### Production Websites

```json theme={null}
{
  "protocol": "https",
  "protocolConfig": {
    "host": "myapp.vercel.app",
    "port": 443,
    "path": "/",
    "expectedStatusCodes": [200, 301, 302]
  }
}
```

#### API Routes

```json theme={null}
{
  "protocol": "https",
  "protocolConfig": {
    "host": "myapp.vercel.app",
    "port": 443,
    "path": "/api/health",
    "expectedResponse": {
      "status": "ok"
    }
  }
}
```

#### Preview Deployments

```json theme={null}
{
  "protocol": "https",
  "protocolConfig": {
    "host": "myapp-git-feature.vercel.app",
    "port": 443,
    "path": "/",
    "deploymentType": "preview"
  }
}
```

    {
      "source": "/old-path",
      "destination": "/new-path",
      "type": "rewrite"
    }
  ]
}
```

## Security Considerations

### Vercel Security

* **Token Management**: Gebruik dedicated monitoring tokens
* **Scope Limitation**: Beperk token toegang tot benodigde projecten
* **Token Rotation**: Vernieuw tokens regelmatig
* **Audit Logging**: Vercel API call logging

### PulseGuard Security

* **Encrypted Storage**: Vercel tokens worden versleuteld opgeslagen
* **Read-only Access**: Alleen read permissies vereist
* **API Rate Limiting**: Vercel API limits worden gerespecteerd
* **Audit Trail**: Alle Vercel API calls worden gelogd

## Troubleshooting

### Veelvoorkomende Problemen

#### "Invalid Vercel token"

**Oorzaken:**

* Token is verlopen of ingetrokken
* Token heeft onvoldoende permissies
* Token is voor verkeerd account

**Oplossingen:**

1. Creëer nieuwe token in Vercel dashboard
2. Controleer token permissies
3. Verificeer account ownership

#### "No projects found"

**Oorzaken:**

* Geen Vercel projecten in account
* Token heeft geen toegang tot projecten
* Team permissions ontbreken

**Oplossingen:**

1. Controleer Vercel dashboard voor projecten
2. Verificeer token scopes
3. Check team membership permissions

#### "Deployment monitoring fails"

**Oorzaken:**

* Deployment is verwijderd in Vercel
* Project permissions gewijzigd
* API rate limits bereikt

**Oplossingen:**

1. Re-sync Vercel integration
2. Controleer project permissions
3. Monitor API usage limits

#### Function timeout errors

**Oorzaken:**

* Vercel function timeouts
* Network connectivity issues
* Function code errors

**Oplossingen:**

1. Controleer Vercel function logs
2. Verificeer function configuration
3. Test function endpoints manually

## Performance Optimization

### Monitoring Frequency

* **Critical APIs**: Elke 30 seconden - 1 minuut
* **Production Sites**: Elke 1 - 5 minuten
* **Preview Deployments**: Elke 5 - 15 minuten
* **Functions**: Elke 1 - 5 minuten

### Vercel API Limits

* **Rate Limits**: 2000 requests per uur per token

# Vercel accounts ophalen
curl -H "Authorization: Bearer YOUR_TOKEN" https://api.ipulse.one/vercel/accounts

# Vercel account koppelen
curl -X POST https://api.ipulse.one/vercel/accounts \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "accessToken": "vercel-access-token"
  }'

# Vercel projecten ontdekken
