### Liquid: Dynamic For Loops with Blocks

Source: https://dreamlit.ai/docs/steps/send-slack

This example shows how to use Liquid's `{% for %}` loop to dynamically generate a list of blocks based on an array of input data. This is useful for creating repetitive message structures, such as listing items in an order.

```liquid
{
  "blocks": [
    {% for item in orders %}
    {
      "type": "section",
      "text": {
        "type": "mrkdwn",
        "text": "• *{{ item.name }}*: ${{ item.price }}"
      }
    }{% if forloop.last == false %},{% endif %}
    {% endfor %}
  ]
}
```

### Personalize Email Subject with Liquid

Source: https://dreamlit.ai/docs/steps/send-email

This example demonstrates how to use Liquid templating to personalize the email subject line by referencing fields from the input data, such as 'first_name'. This allows for dynamic and relevant email subjects.

```liquid
Hi {{ first_name }}, thanks for signing up!
```

### Dreamlit Transactional Notification Workflow

Source: https://dreamlit.ai/docs/getting-started/use-cases

Illustrates a common pattern for transactional notifications using Dreamlit. It involves a trigger, a wait step, a query to filter recipients, and a notification step. This approach simplifies reasoning and testing compared to cron jobs.

```mermaid

    trigger["Database trigger\nruns on save"] -->|"On row\nsave"| wait["Wait\nuntil specific time\nor for a duration"]
    wait -->|"After specified\ndelay"| query["Query step\nthat fetches or\nfilters users"]
    query -->|"For each\nqualified user"| notify["Notification step\n"]

```

### SQL Query for Data Enrichment

Source: https://dreamlit.ai/docs/steps/query

This SQL query demonstrates how to enrich input data by joining it with an organization table. It selects all columns from the input rows and adds the organization name based on a common ID. The `input_rows` table contains data from the previous step, and `organization` is a table in the selected database connection.

```sql
SELECT input_row.*
      org.organization_name
FROM input_rows AS input_row
JOIN organization AS org
  ON input_row.organization_id = org.id;
```

### Liquid: Simple Variable Substitution

Source: https://dreamlit.ai/docs/steps/send-slack

This snippet demonstrates how to directly substitute input data fields into a message string using Liquid's `{{ }}` syntax. It's useful for personalizing messages with specific data like customer emails.

```liquid
{
  "text": "New signup: {{ email }}"
}
```

This Mermaid sequence diagram illustrates the flow of an authentication email trigger, from the user's application making a Supabase API call to Dreamlit sending a custom email to the user. It highlights the roles of the App, Supabase Auth, the Auth Hook, and Dreamlit in the process.

```mermaid
sequenceDiagram  theme={null}  participant App as Your App  participant Supabase as Supabase Auth  participant Hook as Auth Hook  participant Dreamlit as Dreamlit  actor User as Your Users

  App->>Supabase: Call auth API  Supabase->>Hook: Trigger auth event  Hook->>Dreamlit: Forward event  Dreamlit->>User: Send custom email
```

### Sequence Diagram for Event Lifecycle in Dreamlit AI

Source: https://dreamlit.ai/docs/getting-started/how-it-works

This Mermaid sequence diagram illustrates the flow of an event through the Dreamlit AI system, from application activity to end-user notification. It depicts interactions between the user's application, database, the `dreamlit.event_log` table, and the Dreamlit Engine.

```mermaid
sequenceDiagram
    box Your Application
    participant App as Your Application
    participant DB as Your Database
    participant EventLog as dreamlit.event_log <br> in Your Database
    end
    participant Dreamlit as Dreamlit Engine
    actor User as Your End User

    Note over App: Some activity
    App->>DB: Insert/update row
    Note over DB: Row changed
    DB->>EventLog: Trigger executes
    Note over EventLog: Event recorded
    Dreamlit->>EventLog: Monitor changes
    Note over Dreamlit: Workflow triggered
    Dreamlit-->>User: Send notification
```

### Verify DNS Records with Shell Commands (macOS/Linux)

Source: https://dreamlit.ai/docs/configuration/email

This snippet provides bash commands for macOS and Linux users to verify DNS records for MX, SPF, DMARC, and DKIM. It helps confirm that DNS changes have propagated correctly after setting up a custom email domain. Users need to replace placeholder domain names with their actual domain.

```bash
dig MX mail.mydomain.com
```

```bash
dig TXT mail.mydomain.com
```

```bash
dig TXT _dmarc.mail.mydomain.com
```

```bash
dig CNAME dk1._domainkey.mail.mydomain.com
dig CNAME dk2._domainkey.mail.mydomain.com
dig CNAME dk3._domainkey.mail.mydomain.com
```

### Liquid: Conditional Formatting

Source: https://dreamlit.ai/docs/steps/send-slack

This snippet illustrates how to use Liquid's conditional statements (`{% if %}`, `{% else %}`, `{% endif %}`) to customize message content based on specific conditions. It allows for dynamic message variations depending on data like customer status.

```liquid
{
  "text": "{% if isPremium %}Premium customer {{ name }} has placed an order!{% else %}Order received from {{ name }}.{% endif %}"
}
```

### Check MX Records using nslookup

Source: https://dreamlit.ai/docs/configuration/email

Use this command to verify the Mail Exchanger (MX) records for your domain, which direct email to the correct mail servers. This is crucial for ensuring emails sent to your domain are routed properly. It requires the nslookup utility.

```bash
nslookup -type=mx mail.mydomain.com
```

### Send Slack Message - Construct JSON Payload

Source: https://dreamlit.ai/docs/steps/send-slack

This snippet demonstrates how to construct a JSON payload for a Slack message using Block Kit components. It utilizes input data fields like 'customer.name' for dynamic content. The generated payload is sent to Slack's Incoming Webhooks API.

```json
{
  "type": "section",
  "text": {
    "type": "mrkdwn",
    "text": "New order placed by *{{ customer.name }}*."
  }
}
```

### Supabase Auth Password Reset Email

Source: https://dreamlit.ai/docs/getting-started/faq

This snippet demonstrates how Dreamlit intercepts Supabase authentication events, such as a password reset request, to send custom, production-ready emails. It highlights the benefit of using Dreamlit over Supabase's default email service, which is not intended for production use.

```javascript
supabase.auth.resetPasswordForEmail("user@example.com");
```
