## Adding New Features
|
||||
|
||||
### Adding a New Service
|
||||
|
||||
1. Add the service struct in `pkg/client/services.go` or a new file
|
||||
2. Add the service to the `Client` struct in `pkg/client/client.go`
|
||||
3. Initialize the service in `NewClient()`
|
||||
4. Implement service methods following existing patterns
|
||||
5. Add tests for the new service
|
||||
6. Update documentation
|
||||
|
||||
Example:
|
||||
```go
|
||||
// NewService represents operations for new resources
|
||||
type NewService struct {
|
||||
client *Client
|
||||
}
|
||||
|
||||
func (s *NewService) Get(ctx context.Context, id uuid.UUID) (*models.NewResource, error) {
|
||||
var resource models.NewResource
|
||||
path := joinPath("/new_resources", id.String())
|
||||
if err := s.client.get(ctx, path, &resource); err != nil {
|
||||
return nil, fmt.Errorf("failed to get resource: %w", err)
|
||||
}
|
||||
return &resource, nil
|
||||
}
|
||||
```
|
||||
|
||||
### Adding New Models
|
||||
|
||||
1. Add model structs in `pkg/models/models.go`
|
||||
2. Follow existing naming conventions (`Resource`, `ResourceCreate`, `ResourceUpdate`)
|
||||
3. Use proper JSON tags
|
||||
4. Add documentation comments
|
||||
|
||||
## Testing
|
||||
|
||||
### Unit Tests
|
||||
|
||||
- Write unit tests for all new functions
|
||||
- Use table-driven tests when appropriate
|
||||
- Mock external dependencies
|
||||
- Aim for >80% code coverage
|
||||
|
||||
### Integration Tests
|
||||
|
||||
- Add integration tests for API operations
|
||||
- Use the `integration` build tag
|
||||
- Clean up resources after tests
|
||||
- Handle test failures gracefully
|
||||
|
||||
## Documentation
|
||||
|
||||
### GoDoc
|
||||
|
||||
- Add package-level documentation
|
||||
- Document all exported types and functions
|
||||
- Include examples in documentation when helpful
|
||||
- Use proper formatting (code blocks, links, etc.)
|
||||
|
||||
### Examples
|
||||
|
||||
- Add examples for new features in `examples/`
|
||||
- Make examples runnable and self-contained
|
||||
- Include error handling
|
||||
- Add comments explaining key concepts
|
||||

||||
|
||||
// Flows auflisten mit Pagination
|
||||
iter := client.Flows.ListAll(ctx, &models.FlowFilter{
|
||||
Tags: []string{"production"},
|
||||
})
|
||||
for iter.Next(ctx) {
|
||||
flow := iter.Value()
|
||||
fmt.Printf("Flow: %s\n", flow.Name)
|
||||
}
|
||||
if err := iter.Err(); err != nil {
|
||||
log.Fatal(err)
|
||||
}
|
||||
|
||||
// Flow löschen
|
||||
err := client.Flows.Delete(ctx, flowID)
|
||||
```
|
||||
|
||||
### Flow-Runs verwalten
|
||||
|
||||
```go
|
||||
// Flow-Run erstellen und starten
|
||||
run, err := client.FlowRuns.Create(ctx, &models.FlowRunCreate{
|
||||
FlowID: flowID,
|
||||
Name: "scheduled-run",
|
||||
Parameters: map[string]interface{}{
|
||||
"param1": "value1",
|
||||
"param2": 42,
|
||||
},
|
||||
})
|
||||
|
||||
// Auf Completion warten
|
||||
finalRun, err := client.FlowRuns.Wait(ctx, run.ID, 5*time.Second)
|
||||
fmt.Printf("Flow-Run Status: %s\n", finalRun.StateType)
|
||||
```
|
||||
|
||||
### Deployments erstellen
|
||||
|
||||
```go
|
||||
deployment, err := client.Deployments.Create(ctx, &models.DeploymentCreate{
|
||||
Name: "my-deployment",
|
||||
FlowID: flowID,
|
||||
WorkPoolName: "default-pool",
|
||||
Schedules: []models.DeploymentScheduleCreate{
|
||||
{
|
||||
Schedule: models.IntervalSchedule{

# OpenAPI Specification for Prefect Server API
|
||||
|
||||
This directory contains the OpenAPI specification for the Prefect v3 Server REST API.
|
||||
|
||||
## How to obtain the OpenAPI spec
|
||||
|
||||
The OpenAPI specification is available from a running Prefect server instance.
|
||||
|
||||
### Option 1: From a local Prefect server
|
||||
|
||||
1. Start a Prefect server:
|
||||
```bash
|
||||
prefect server start
|
||||
```
|
||||
|
||||
2. Download the OpenAPI specification:
|
||||
```bash
|
||||
curl http://localhost:4200/openapi.json -o api/openapi.json
|
||||
```
|
||||
|
||||
### Option 2: From Prefect Cloud
|
||||
|
||||
```bash
|
||||
curl https://api.prefect.cloud/api/openapi.json -o api/openapi.json
|
||||
```
|
||||
|
||||
## Generating Go code
|
||||
|
||||
After obtaining the OpenAPI specification, run:
|
||||
|
||||
```bash
|
||||
make generate
|
||||
```
|
||||
|
||||
This will generate Go types and client code from the OpenAPI spec.
|
||||
|
||||
## Note
|
||||
|
||||
The `openapi.json` file is not included in the repository by default. You need to obtain it from a running Prefect server instance as described above.
|
||||
|
||||
For development purposes, a minimal placeholder spec is provided to allow the project to compile without a full Prefect server setup.

/*
|
||||
Package prefect provides a Go client for interacting with the Prefect Server API.
|
||||
|
||||
The client supports all major Prefect operations including flows, flow runs,
|
||||
deployments, tasks, work pools, and more. It includes built-in retry logic,
|
||||
pagination support, and comprehensive error handling.
|
||||
|
||||
# Installation
|
||||
|
||||
go get github.com/gregor/prefect-go
|
||||
|
||||
# Quick Start
|
||||
|
||||
Create a client and interact with the Prefect API:
|
||||
|
||||
package main
|
||||
|
||||
import (
|
||||
"context"
|
||||
"log"
|
||||
|
||||
"github.com/gregor/prefect-go/pkg/client"
|
||||
"github.com/gregor/prefect-go/pkg/models"
|
||||
)
|
||||
|
||||
func main() {
|
||||
// Create a new client
|
||||
c, err := client.NewClient(
|
||||
client.WithBaseURL("http://localhost:4200/api"),
|
||||
)
|
||||
if err != nil {
|
||||
log.Fatal(err)
|
||||
}
|
||||
|
||||
ctx := context.Background()
|
||||
|
||||
// Create a flow
|
||||
flow, err := c.Flows.Create(ctx, &models.FlowCreate{
|
||||
Name: "my-flow",
|
||||
Tags: []string{"example"},
|
||||
})
|
||||
if err != nil {
|
||||
log.Fatal(err)
|
||||
}
|
||||
|
||||
log.Printf("Created flow: %s (ID: %s)", flow.Name, flow.ID)
|
||||
}
|
||||
|
||||
# Client Configuration
|
||||
|
||||
The client can be configured with various options:
|
||||
|
||||
client, err := client.NewClient(
|
||||
client.WithBaseURL("http://localhost:4200/api"),
|
||||
client.WithAPIKey("your-api-key"),
|
||||
client.WithTimeout(30 * time.Second),
|
||||
client.WithRetry(retry.Config{
|
||||
MaxAttempts: 5,
|
||||
InitialDelay: time.Second,
|
||||
}),
|
||||
)
|
||||
|
||||
# Services
|
||||
|
||||
The client provides several services for different resource types:
|
||||
|
||||
- Flows: Flow management operations
|
||||
- FlowRuns: Flow run operations and monitoring
|
||||
- Deployments: Deployment creation and management
|
||||
- TaskRuns: Task run operations
|
||||
- WorkPools: Work pool management
|
||||
- WorkQueues: Work queue operations
|
||||
- Variables: Variable storage and retrieval
|
||||
- Logs: Log creation and querying
|
||||
- Admin: Administrative operations (health, version)
|
||||
|
||||
# Error Handling
|
||||
|
||||
The package provides structured error types for API errors:
|
||||
|
||||
flow, err := client.Flows.Get(ctx, flowID)
|
||||
if err != nil {
|
||||
if errors.IsNotFound(err) {
|
||||
log.Println("Flow not found")
|
||||
} else if errors.IsUnauthorized(err) {
|
||||
log.Println("Authentication required")
|
||||
} else {
|
||||
log.Printf("API error: %v", err)
|
||||
}
|
||||
}
|
||||
|
||||
# Pagination
|
||||
|
||||
For endpoints that return lists, use pagination:
|
||||
|
||||
// Manual pagination
|
||||
page, err := client.Flows.List(ctx, filter, 0, 100)
|
||||
|
||||
// Automatic pagination with iterator
|
||||
iter := client.Flows.ListAll(ctx, filter)
|
||||
for iter.Next(ctx) {
|
||||
flow := iter.Value()
|
||||
// Process flow
|
||||
}
|
||||
if err := iter.Err(); err != nil {
|
||||
log.Fatal(err)
|
||||
}
|
||||
|
||||
# Retry Logic
|
||||
|
||||
The client automatically retries failed requests with exponential backoff:
|
||||
|
||||
- Retries on transient errors (5xx, 429)
|
||||
- Respects Retry-After headers
|
||||
- Context-aware cancellation
|
||||
- Configurable retry behavior
|
||||
|
||||
# Monitoring Flow Runs
|
||||
|
||||
Wait for a flow run to complete:
|
||||
|
||||
finalRun, err := client.FlowRuns.Wait(ctx, runID, 5*time.Second)
|
||||
if err != nil {
|
||||
log.Fatal(err)
|
||||
}
|
||||
log.Printf("Flow run completed with state: %v", finalRun.StateType)
|
||||
|
||||
For more examples, see the examples/ directory in the repository.

# Integration Tests
|
||||
|
||||
Integration tests require a running Prefect server instance.
|
||||
|
||||
## Running Integration Tests
|
||||
|
||||
### 1. Start a Prefect Server
|
||||
|
||||
```bash
|
||||
prefect server start
|
||||
```
|
||||
|
||||
This will start a Prefect server on `http://localhost:4200`.
|
||||
|
||||
### 2. Run the Integration Tests
|
||||
|
||||
```bash
|
||||
go test -v -tags=integration ./pkg/client/
|
||||
```
|
||||
|
||||
Or using make:
|
||||
|
||||
```bash
|
||||
make test-integration
|
||||
```
|
||||
|
||||
### 3. Custom Server URL
|
||||
|
||||
If your Prefect server is running on a different URL, set the `PREFECT_API_URL` environment variable:
|
||||
|
||||
```bash
|
||||
export PREFECT_API_URL="http://your-server:4200/api"
|
||||
go test -v -tags=integration ./pkg/client/
|
||||
```
|
||||
|
||||
## Test Coverage
|
||||
|
||||
The integration tests cover:
|
||||
|
||||
- **Flow Lifecycle**: Create, get, update, list, and delete flows
|
||||
- **Flow Run Lifecycle**: Create, get, set state, and delete flow runs
|
||||
- **Deployment Lifecycle**: Create, get, pause, resume, and delete deployments
|
||||
- **Pagination**: Manual pagination and iterator-based pagination
|
||||
- **Variables**: Create, get, update, and delete variables
|
||||
- **Admin Endpoints**: Health check and version
|
||||
- **Flow Run Monitoring**: Wait for flow run completion
|
||||
|
||||
## Notes
|
||||
|
||||
- Integration tests use the `integration` build tag to separate them from unit tests
|
||||
- Each test creates and cleans up its own resources
|
||||
- Tests use unique UUIDs in names to avoid conflicts
|
||||
- Some tests may take several seconds to complete (e.g., flow run wait tests)
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Connection Refused
|
||||
|
||||
If you see "connection refused" errors, make sure:
|
||||
1. Prefect server is running (`prefect server start`)
|
||||
2. The server is accessible at the configured URL
|
||||
3. No firewall is blocking the connection
|
||||
|
||||
### Test Timeout
|
||||
|
||||
If tests timeout:
|
||||
1. Increase the test timeout: `go test -timeout 5m -tags=integration ./pkg/client/`
|
||||
2. Check server logs for errors
|
||||
3. Ensure the server is not under heavy load
