Atlas SDK for Go

An SDK for building ariga/atlas providers in Go.

Installation

go get -u friendliai/atlas-go-sdk

How to use

To use the SDK, you need to create a new client with your migrations folder and the atlas binary path.

package main

import (
    ...
    "friendliai/atlas-go-sdk/atlasexec"
)

func main() {
    // Create a new client
    client, err := atlasexec.NewClient("my-migration-folder", "my-atlas-cli-path")
    if err != nil {
        log.Fatalf("failed to create client: %v", err)
    }
}

APIs

The SDK provides the following APIs:

• Login: Login to the Atlas Cloud
• Logout: runs the "atlas logout" command.
• MigratePush: runs the "atlas migrate push" command.
• MigrateLint: runs the "atlas migrate lint" command.
• MigrateApplySlice: runs the "atlas migrate apply" command for multiple targets.
• MigrateApply: runs the "atlas migrate apply" command.
• MigrateApplySlice: runs the 'atlas migrate apply' command for multiple targets.
• MigrateDown: runs the "atlas migrate down" command.
• MigrateStatus: runs the "atlas migrate status" command.
• MigrateTest: runs the "atlas migrate test" command.
• SchemaApply: runs the "atlas schema apply" command.
• SchemaInspect: runs the "atlas schema inspect" command.
• SchemaDiff: runs the "atlas schema diff" command.
• SchemaTest: runs the "atlas schema test" command.

Example with MigrateApply API:

package main

import (
    "context"
    "fmt"
    "log"
    "os"

    "friendliai/atlas-go-sdk/atlasexec"
)

func main() {
    // Define the execution context, supplying a migration directory
    // and potentially an `atlas.hcl` configuration file using `atlasexec.WithHCL`.
    workdir, err := atlasexec.NewWorkingDir(
        atlasexec.WithMigrations(
            os.DirFS("./migrations"),
        ),
    )
    if err != nil {
        log.Fatalf("failed to load working directory: %v", err)
    }
    // atlasexec works on a temporary directory, so we need to close it
    defer workdir.Close()

    // Initialize the client.
    client, err := atlasexec.NewClient(workdir.Path(), "atlas")
    if err != nil {
        log.Fatalf("failed to initialize client: %v", err)
    }
    // Run `atlas migrate apply` on a SQLite database under /tmp.
    res, err := client.MigrateApply(context.Background(), &atlasexec.MigrateApplyParams{
        URL: "sqlite:///tmp/demo.db?_fk=1&cache=shared",
    })
    if err != nil {
        log.Fatalf("failed to apply migrations: %v", err)
    }
    fmt.Printf("Applied %d migrations\n", len(res.Applied))
}
