Use Cases

1. API Testing and Validation

FlowLang excels at quick API testing without the overhead of larger frameworks.

let endpoint = "https://api.example.com/health"
let response = http_get(endpoint)
print "API Status:"
print response

2. Data Pipeline Automation

Create ETL (Extract, Transform, Load) workflows with minimal code.

func etl_pipeline(source_id) {
  let data = http_get("https://api.source.com/data/" + str(source_id))
  let transformed = str(data)
  write_file("output_" + str(source_id) + ".txt", transformed)
  return "Complete"
}

let ids = range(1, 10)
let i = 1
while i < 10 {
  etl_pipeline(i)
  let i = i + 1
}

3. Configuration Management

Automate configuration file generation and updates.

func generate_config(env) {
  let config = "environment=" + env
  write_file(env + "_config.txt", config)
  return "Config generated for " + env
}

generate_config("production")
generate_config("staging")

4. Microservice Orchestration

Coordinate calls across multiple microservices.

func orchestrate() {
  let users = http_get("https://api.service1.com/users")
  let orders = http_get("https://api.service2.com/orders")
  
  write_file("users.txt", str(users))
  write_file("orders.txt", str(orders))
  
  return "Orchestration complete"
}

orchestrate()

5. Scheduled Tasks and Cron Jobs

Perfect for periodic data collection and processing tasks.

func daily_report() {
  let data = http_get("https://api.example.com/daily-stats")
  let timestamp = str(data)
  write_file("daily_report.txt", timestamp)
  return "Report generated"
}

daily_report()

6. Web Scraping and Data Collection

Collect data from multiple sources efficiently.

func collect_data(urls) {
  let count = 1
  while count <= 5 {
    let url = "https://api.data.com/item/" + str(count)
    let data = http_get(url)
    write_file("data_" + str(count) + ".txt", str(data))
    let count = count + 1
  }
  return "Collection complete"
}

collect_data()

7. DevOps Automation

Automate deployment and infrastructure tasks.

func deploy_service(service_name) {
  let health = http_get("https://" + service_name + ".com/health")
  
  if type(health) == "dict" {
    print "Service healthy, proceeding with deployment"
    let deploy_result = http_post(
      "https://deploy.com/trigger",
      {"service": service_name}
    )
    return deploy_result
  }
  
  return "Service unhealthy, aborting"
}

let result = deploy_service("my-api")
print result

8. Log Processing and Analysis

Process and analyze log files.

func process_logs(log_file) {
  let content = read_file(log_file)
  let summary = "Processed: " + str(len(content)) + " characters"
  write_file("log_summary.txt", summary)
  return summary
}

let result = process_logs("server.log")
print result

9. Backup and Sync Operations

Automate data backup and synchronization.

func backup_to_api(file_path) {
  let content = read_file(file_path)
  let response = http_post(
    "https://backup.com/upload",
    {"content": content, "filename": file_path}
  )
  return response
}

let result = backup_to_api("important_data.txt")
print result

10. Integration Testing

Test integration between multiple systems.

func test_integration() {
  let auth = http_get("https://auth.service.com/token")
  let data = http_get("https://api.service.com/data")
  
  if type(auth) == "dict" {
    if type(data) == "dict" {
      print "Integration test passed"
      return "PASS"
    }
  }
  
  return "FAIL"
}

let result = test_integration()
print result
