Class: Sandbox

AgentBox cloud sandbox is a secure and isolated cloud environment.

The sandbox allows you to:

Access Linux OS
Create, list, and delete files and directories
Run commands
Run isolated code
Access the internet

Use Sandbox.create to create a new sandbox.

Example

import { Sandbox } from '@abox-dev/code-interpreter'

const sandbox = await Sandbox.create()

Methods

connect()

connect(opts?): Promise<Sandbox>

Connect to a sandbox. If the sandbox is paused, it will be automatically resumed. Sandbox must be either running or be paused.

With sandbox ID you can connect to the same sandbox from different places or environments (serverless functions, etc).

Parameters

opts?

SandboxConnectOpts

connection options.

Returns

Promise<Sandbox>

A running sandbox instance

Example

const sandbox = await Sandbox.create()
await sandbox.pause()

// Connect to the same sandbox.
const sameSandbox = await sandbox.connect()

Inherited from

BaseSandbox.connect

createCodeContext()

createCodeContext(opts?): Promise<Context>

Creates a new context to run code in.

Parameters

opts?

CreateCodeContextOpts

options for creating the context.

Returns

Promise<Context>

context object.

createSnapshot()

createSnapshot(opts?): Promise<SnapshotInfo>

Create a snapshot of the sandbox's current state.

The sandbox will be paused while the snapshot is being created. The snapshot can be used to create new sandboxes with the same filesystem and state. Snapshots are persistent and survive sandbox deletion.

Use the returned snapshotId with Sandbox.create(snapshotId) to create a new sandbox from the snapshot.

Parameters

opts?

CreateSnapshotOpts

snapshot creation options including optional name and connection options.

Returns

Promise<SnapshotInfo>

snapshot information including the snapshot ID.

Example

const sandbox = await Sandbox.create()
await sandbox.files.write('/app/state.json', '{"step": 1}')

// Create a snapshot
const snapshot = await sandbox.createSnapshot({ name: 'my-snapshot' })

// Create a new sandbox from the snapshot
const newSandbox = await Sandbox.create(snapshot.snapshotId)

Inherited from

BaseSandbox.createSnapshot

downloadUrl()

downloadUrl(path, opts?): Promise<string>

Get the URL to download a file from the sandbox.

Parameters

path

string

path to the file in the sandbox.

opts?

SandboxUrlOpts

download url options.

Returns

Promise<string>

URL for downloading file.

Inherited from

BaseSandbox.downloadUrl

fork()

fork(opts?): Promise<(Error | Sandbox)[]>

Fork the sandbox.

The sandbox is checkpointed in place (briefly paused, snapshotted with its full memory state, and resumed — its ID and expiration stay untouched) and count new sandboxes are created from that snapshot. All forks boot from the same snapshot, so the snapshot is captured once regardless of count.

Each fork succeeds or fails independently — the returned array contains one entry per requested fork, either a running Sandbox instance or an Error describing why that fork failed to start (Promise.allSettled-style). Per-fork error codes map to the same error classes as other API errors (e.g. 429 to RateLimitError).

Parameters

opts?

SandboxForkOpts

fork options — count, timeoutMs and connection options.

Returns

Promise<(Error | Sandbox)[]>

array with one entry per requested fork — a sandbox instance or an error.

Example

const sandbox = await Sandbox.create()

const [fork1, fork2] = await sandbox.fork({ count: 2 })
if (fork1 instanceof Sandbox) {
  await fork1.commands.run('echo "hello from fork"')
}

Inherited from

BaseSandbox.fork

getHost()

getHost(port): string

Get the host address for the specified sandbox port. You can then use this address to connect to the sandbox port from outside the sandbox via HTTP or WebSocket.

Parameters

port

number

number of the port in the sandbox.

Returns

string

host address of the sandbox port.

Example

const sandbox = await Sandbox.create()
// Start an HTTP server
await sandbox.commands.run('python3 -m http.server 3000', { background: true })
// Get the hostname of the HTTP server
const serverURL = sandbox.getHost(3000)

Inherited from

BaseSandbox.getHost

getInfo()

getInfo(opts?): Promise<SandboxInfo>

Get sandbox information like sandbox ID, template, metadata, started at/end at date.

Parameters

Pick<SandboxOpts, "signal" | "requestTimeoutMs">

connection options.

Returns

Promise<SandboxInfo>

information about the sandbox

Inherited from

BaseSandbox.getInfo

getMetrics()

getMetrics(opts?): Promise<SandboxMetrics[]>

Get the metrics of the sandbox.

Parameters

opts?

SandboxMetricsOpts

connection options.

Returns

Promise<SandboxMetrics[]>

List of sandbox metrics containing CPU, memory and disk usage information.

Inherited from

BaseSandbox.getMetrics

isRunning()

isRunning(opts?): Promise<boolean>

Check if the sandbox is running.

Parameters

opts?

Pick<ConnectionOpts, "signal" | "requestTimeoutMs">

Returns

Promise<boolean>

true if the sandbox is running, false otherwise.

Example

const sandbox = await Sandbox.create()
await sandbox.isRunning() // Returns true

await sandbox.kill()
await sandbox.isRunning() // Returns false

Inherited from

BaseSandbox.isRunning

kill()

kill(opts?): Promise<boolean>

Kill the sandbox.

Parameters

opts?

Pick<SandboxOpts, "signal" | "requestTimeoutMs">

connection options.

Returns

Promise<boolean>

true if the sandbox was killed, false if the sandbox was not found.

Inherited from

BaseSandbox.kill

listCodeContexts()

listCodeContexts(): Promise<Context[]>

List all contexts.

Returns

Promise<Context[]>

list of contexts.

listSnapshots()

listSnapshots(opts?): SnapshotPaginator

List all snapshots created from this sandbox.

Parameters

opts?

Omit<SnapshotListOpts, "sandboxId">

list options.

Returns

SnapshotPaginator

paginator for listing snapshots from this sandbox.

Inherited from

BaseSandbox.listSnapshots

pause()

pause(opts?): Promise<boolean>

Pause a sandbox by its ID.

Parameters

opts?

SandboxPauseOpts

connection options, plus keepMemory to control the snapshot kind. When opts.keepMemory is false, the in-memory state is dropped and only the filesystem is persisted (a filesystem-only snapshot); resuming such a sandbox cold-boots (reboots) it from disk, losing running processes and open connections. Defaults to true (full memory snapshot).

Returns

Promise<boolean>

true if the sandbox got paused, false if the sandbox was already paused.

Example

const sandbox = await Sandbox.create()
await sandbox.pause()

// filesystem-only snapshot (resume reboots the sandbox)
await sandbox.pause({ keepMemory: false })

Inherited from

BaseSandbox.pause
