You can list sandboxes using the Sandbox.list() method.
Once you have information about running sandbox, you can connect to it using the Sandbox.connect() method.
import { Sandbox } from 'novita-sandbox/code-interpreter'

// Create a sandbox.
const sandbox = await Sandbox.create({
  metadata: {
    name: 'My Sandbox',
  },
})

// List all running sandboxes.
const runningSandboxesPaginator = await Sandbox.list({
  query: {
    state: ["running"],
  },
})

const runningSandboxes = await runningSandboxesPaginator.nextItems()
const runningSandbox = runningSandboxes[0]

console.log('Running sandbox metadata:', runningSandbox.metadata)
console.log('Running sandbox id:', runningSandbox.sandboxId)
console.log('Running sandbox started at:', runningSandbox.startedAt)
console.log('Running sandbox template id:', runningSandbox.templateId)

await sandbox.kill()

​
Filtering sandboxes

You can filter sandboxes by specifying Metadata key value pairs. Specifying multiple key value pairs will return sandboxes that match all of them. This can be useful when you have a large number of sandboxes and want to find only specific ones. The filtering is performed on the server. 
import { Sandbox } from 'novita-sandbox/code-interpreter'

// Create a sandbox with metadata.
const sandbox = await Sandbox.create({
  metadata: {
    env: 'dev',
    app: 'my-app',
    userId: '123',
  },
})

// List all running sandboxes that has `userId` key with value `123` and `env` key with value `dev`.
const runningSandboxesPaginator = await Sandbox.list({
  query: {
    metadata: { userId: '123', env: 'dev' },
  },
})

const runningSandboxes = await runningSandboxesPaginator.nextItems()
for (const runningSandbox of runningSandboxes) {
  console.log(`list running sandbox (${runningSandbox.sandboxId}) metadata:`, runningSandbox.metadata)
}

await sandbox.kill()

​
Listing sandboxes

The Sandbox.list() method now supports pagination. In the advanced pagination section, you can find more information about pagination techniques using the updated method. 
import { Sandbox } from 'novita-sandbox/code-interpreter'

const sandbox = await Sandbox.create()

const paginator = Sandbox.list()

// Get the first page of sandboxes (running and paused)
const firstPage = await paginator.nextItems()
if (paginator.hasNext) {
    // Get the next page of sandboxes
    const nextPage = await paginator.nextItems()
}

await sandbox.kill()

​
Filtering sandboxes

Filter sandboxes by their current state. The state parameter can contain either “running” for running sandboxes or “paused” for paused sandboxes, or both. 
import { Sandbox } from 'novita-sandbox/code-interpreter'

const sandbox = await Sandbox.create()

// List all sandboxes that are running or paused.
const paginator = Sandbox.list({
  query: {
    state: ['running', 'paused'],
  },
})

const sandboxes = await paginator.nextItems()

await sandbox.kill()
Filter sandboxes by the metadata key value pairs specified during Sandbox creation. 
import { Sandbox } from 'novita-sandbox/code-interpreter'

// Create sandbox with metadata.
const sandbox = await Sandbox.create({
  metadata: {
    env: 'dev',
    app: 'my-app',
    userId: '123',
  },
})

// List all sandboxes that has `userId` key with value `123` and `env` key with value `dev`.
const paginator = Sandbox.list({
  query: {
    metadata: { userId: '123', env: 'dev' },
  },
})

const sandboxes = await paginator.nextItems()

await sandbox.kill()

​
Advanced pagination

For more granular pagination, you can set custom per-page item limit (default and maximum is 1000) and specify an offset parameter (nextToken or next_token) to start paginating from. 
import { Sandbox } from 'novita-sandbox/code-interpreter'

const sandbox = await Sandbox.create()

const paginator = Sandbox.list({
  limit: 1000,
  // nextToken: '<base64-encoded-token>',
})

// Fetch the next page
await paginator.nextItems()

// Additional paginator properties
// Whether there is a next page
console.log("paginator.hasNext: ", paginator.hasNext)

// Next page token
console.log("paginator.nextToken: ", paginator.nextToken)

await sandbox.kill()
You can fetch all pages by looping through the paginator while checking if there is a next page (using hasNext or has_next property) and fetching until there are no more pages left to fetch: 
import { Sandbox, SandboxInfo } from 'novita-sandbox/code-interpreter'

const sandbox = await Sandbox.create()

const paginator = Sandbox.list()

const sandboxes: SandboxInfo[] = []
while (paginator.hasNext) {
  const items = await paginator.nextItems()
  sandboxes.push(...items)
}

for (const sandbox of sandboxes) {
  console.log(`list sandbox (${sandbox.sandboxId})`)
}

await sandbox.kill()
