Adds a `gzip` option to the template `.copy()` / `copyItems` layer that
controls whether copied files are gzipped before upload, threaded from
the copy call through the build-time tar stream in both the JS SDK and
the sync/async Python SDKs. It is enabled by default to preserve
existing behavior, so passing `gzip: false` (`gzip=False`) uploads an
uncompressed tar — useful for already-compressed payloads where gzip
adds CPU cost without shrinking the upload. The option name matches
node-tar's own `gzip` option and the existing sandbox filesystem `gzip`
kwarg. Gzip is deliberately excluded from the file cache hash, so
toggling it does not bust the build cache. Tests in both SDKs were
updated for the new argument and extended with `gzip: false` cases
asserting the archive is not gzipped yet still extracts, and a changeset
(`minor` for both packages) is included.
> [!NOTE]
> The server that extracts these uploaded archives lives in another repo
and must auto-detect compression (peek the gzip `0x1f 0x8b` magic)
rather than assuming gzip; confirm it handles plain tars before release.
## Usage
```ts
// JS/TS
template.copy('model.bin', '/app/', { gzip: false })
template.copyItems([{ src: 'a.bin', dest: '/app/', gzip: false }])
```
```python
# Python (sync & async)
template.copy('model.bin', '/app/', gzip=False)
template.copy_items([{ 'src': 'a.bin', 'dest': '/app/', 'gzip': False }])
```

What is E2B?
E2B is an open-source infrastructure that allows you to run AI-generated code in secure isolated sandboxes in the cloud. To start and control sandboxes, use our JavaScript SDK or Python SDK.
Run your first Sandbox
1. Install SDK
npm i e2b
2. Get your E2B API key
E2B_API_KEY=e2b_***
3. Start a sandbox and run commands
import Sandbox from 'e2b'
const sandbox = await Sandbox.create()
const result = await sandbox.commands.run('echo "Hello from E2B!"')
console.log(result.stdout) // Hello from E2B!
4. Code execution with Code Interpreter
If you need runCode(), install the Code Interpreter SDK:
npm i @e2b/code-interpreter
import { Sandbox } from '@e2b/code-interpreter'
const sandbox = await Sandbox.create()
const execution = await sandbox.runCode('x = 1; x += 1; x')
console.log(execution.text) // outputs 2
5. Check docs
