HelixML API

The HelixML API is a set of tools and interfaces for working with Helix, a project hosted on GitHub at https://github.com/helixml/helix/. The API allows developers to interact with Helix using various programming languages and technologies. This document will cover the key technologies and dependencies of the HelixML API and provide examples for each option, where possible.

Key Technologies and Dependencies

The Big Picture

The HelixML API is designed to be flexible and easy to use, with a focus on the following principles:

  • Modularity: The API is divided into several components, each with a specific function, making it easy to use only the parts you need.
  • Extensibility: The API is designed to be extended with custom plugins and integrations.
  • Performance: The API is built using high-performance technologies to ensure fast and efficient operation.

Design Philosophy

The HelixML API follows a few core design principles:

  • Simplicity: The API is designed to be easy to use and understand, with clear and consistent interfaces.
  • Flexibility: The API is designed to be flexible and adaptable to a wide range of use cases and scenarios.
  • Security: The API is designed with security in mind, using best practices and industry-standard technologies to protect user data and ensure secure communication.

Programming Languages

The HelixML API supports several programming languages, including:

  • Go: The primary language used for the implementation of the HelixML API.
  • Docker: Used for containerization and deployment of the HelixML API.
  • Git: Used for version control and collaboration.
  • PostgreSQL: Used as the primary database for the HelixML API.
  • Go Mocking Framework: Used for testing and mocking in the Go implementation.
  • Gorilla Router: Used for routing in the Go implementation.
  • Gorilla Websocket: Used for real-time communication in the Go implementation.
  • Material UI: Used for the user interface in the HelixML web application.
  • JWT: Used for authentication and authorization in the HelixML API.
  • Go CMP: Used for code generation and maintenance in the Go implementation.

Examples

The following examples demonstrate how to use the HelixML API with various technologies and programming languages.

Go

The HelixML API provides a Go client library for interacting with the API. Here’s an example of how to use the Go client library to create a namespace in Vault:

package main

import (
"context"
"fmt"
"log"

"github.com/hashicorp/vault/api"
)

func main() {
config := &api.Config{
Address: "http://localhost:8200",
}

client, err := api.NewClient(config)
if err != nil {
log.Fatalf("unable to create Vault client: %v", err)
}

client.SetToken("my-vault-token")

secret, err := client.Sys().CreateNamespace(context.Background(), &api.NamespaceCreateRequest{
Path: "my-namespace",
})
if err != nil {
log.Fatalf("unable to create namespace: %v", err)
}

fmt.Printf("namespace created: %+v\n", secret)
}

Docker

The HelixML API provides a Docker image for running the API in a container. Here’s an example of how to run the HelixML API Docker image:

$ docker run -p 8080:8080 -e DEBUG=1 -e STORAGE=local -e STORAGE_LOCAL_ROOTDIR=/charts -v $(pwd)/charts:/charts ghcr.io/helm/chartmuseum:v0.16.1

Git

The HelixML API uses Git for version control and collaboration. Here’s an example of how to clone the HelixML API repository:

$ git clone https://github.com/helixml/helix.git

PostgreSQL

The HelixML API uses PostgreSQL as the primary database for storing data. Here’s an example of how to connect to a PostgreSQL database using the psql command-line client:

$ psql -h localhost -U myuser -d mydatabase

Go Mocking Framework

The HelixML API uses the Go Mocking Framework for testing and mocking in the Go implementation. Here’s an example of how to use the Go Mocking Framework to create a mock of the Vault client:

package main

import (
"context"
"fmt"
"log"

"github.com/golang/mock/gomock"
"github.com/hashicorp/vault/api"
)

func main() {
ctrl := gomock.NewController(nil)
defer ctrl.Finish()

client := api.NewMockClient(ctrl)

secret := &api.Secret{
RequestID: "my-request-id",
LeaseID:   "my-lease-id",
Renewable: true,
LeaseDuration:  api.LeaseDuration(3600),
Data: map[string]interface{}{
"foo": "bar",
},
}

client.EXPECT().Sys().CreateNamespace(context.Background(), g
