You can find a detailed specification of SE2’s APIs here.

The se2-go library helps you easily interact with SE2’s APIs from your Go application. SE2 is designed to run alongside your application in a Kubernetes or Docker Compose environment.

​
Documentation

Like most Go packages, you can find complete and up to date technical documentation for se2-go on pkg.go.dev. Those docs are generated from inline comments in the se2-go source code.

​
Install SE2 for Go

In a directory with a go.mod file, run:

go get github.com/suborbital/se2-go@latest

​
Configuration

This example sets up a basic client with the token generated in Subo or with the web app. The se2.Client object created here assumes that SE2 is running on the same host on its default ports. Head on over to the se2-go repository on GitHub to try out this code and see more examples.

client.go
package main

import (
    "os"

    "github.com/suborbital/se2-go"
)

func client() *se2.Client {
    token, _ := os.LookupEnv("SE2_ENV_TOKEN")
    client, _ := se2.NewClient(se2.LocalConfig(), token)

    return client
}

​
Build and run a plugin

We can now integrate SE2 into an application. se2-go has access to all of SE2’s APIs. It can run builds, list existing plugins, run tests, and execute plugins.

Behind the scenes, se2-go manages authentication, so you don’t have to worry about setting the right HTTP headers when interacting with the SE2 API.

main.go
package main

import (
    "fmt"
    "log"
    "strings"
    "time"

    se2 "github.com/suborbital/se2-go"
)

func main() {
    client := client()

    // This is a local reference to some plugin. Nothing has run in SE2 at this point.
    plugin := se2.NewPlugin("com.suborbital", "acmeco", "default", "tinygo-hey")

    // Request template source code for the above plugin.
    template, _ := client.BuilderTemplate(plugin, "tinygo")

    // Modify the default template
    modified := strings.Replace(template.Contents, "Hello", "Hey there", 1)
    log.Println(modified)

    // Run a remote build for the provided plugin and the modified 'goodbye world'
    // template.
    build, err := client.BuildPluginString(plugin, "tinygo", modified)

    if err != nil {
        log.Fatal(err)
    }

    if !build.Succeeded {
        // Log the builder output to see why the build failed
        log.Fatal(build.OutputLog)
    }

    // Deploy the plugin and get the new reference
    ref, _ := client.PromoteDraft(plugin)

    // Hello!
    time.Sleep(time.Second * 2)
    for _, name := range []string{"Europa", "Io", "Ganymede", "Callisto"} {
        time.Sleep(time.Millisecond * 300)
        result, _, err := client.ExecRefString(ref.Version, name)
        if err != nil {
            log.Fatal(err)
        }

        // Log the execution output
        fmt.Println(string(result))
    }
}

After an SE2 module has been built, it can be executed as much as you like without rebuilding using client.Exec or client.ExecString.
