Reading files

You can use the files.read() method to read files from the sandbox filesystem. 
import { Sandbox } from 'novita-sandbox/code-interpreter'

const sandbox = await Sandbox.create()

// Create a file in the sandbox for testing
const filePathInSandbox = '/tmp/test-file'
await sandbox.files.write(filePathInSandbox, "test-file-content")

const fileContent = await sandbox.files.read(filePathInSandbox)
console.log(fileContent)

await sandbox.kill()

​
Writing single files

You can use the files.write() method to write single files to the sandbox filesystem. 
import { Sandbox } from 'novita-sandbox/code-interpreter'

const sandbox = await Sandbox.create()

const filePathInSandbox = '/tmp/test-file'

const result = await sandbox.files.write(filePathInSandbox, "test-file-content")
console.log(result)

await sandbox.kill()

​
Writing multiple files

You can also use the files.write() method to write multiple files to the sandbox filesystem. 
import { Sandbox } from 'novita-sandbox/code-interpreter'

const sandbox = await Sandbox.create()

const result = await sandbox.files.write([
    { path: '/tmp/test-file-1', data: 'file content 1' },
    { path: '/tmp/test-file-2', data: 'file content 2' }
])

console.log(result)

await sandbox.kill()
