Adds stdin piping support to `e2b sandbox exec`, so users can do:
```bash
echo "data" | e2b sandbox exec <id> -- cat
cat file.bin | e2b sandbox exec <id> -- python3 -c 'import sys;
print(len(sys.stdin.buffer.read()))'
```
Included:
- JS SDK updates:
- closeStdin()
- supportsStdinClose
- CLI updates:
- detects piped stdin
- streams stdin in 64 KiB chunks
- closes remote stdin on EOF
- graceful fallback for older sandbox versions (requires `envd` >= 0.5.2, warn + ignore piped input)
### Example Usage
#### non-piped exec still works
```
e2b sandbox exec <sandbox_id> -- 'echo backend-non-pipe'
```
#### piped stdin path (supported envd) should deliver bytes
```
echo "hello" | e2b sandbox exec <sandbox_id> -- 'wc -c' # expect 6
printf '\x00\x01\x02\xff' | $e2b sandbox exec <sandbox_id> -- 'wc -c' #
expect 4
```
#### optional: legacy template behavior should warn + ignore piped stdin
```
echo "hello" | e2b sandbox exec <legacy_sandbox_id> -- 'wc -c' # expect
0 + "Ignoring piped stdin."
```
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
pip install e2b-code-interpreter
2. Get your E2B API key
E2B_API_KEY=e2b_***
3. Execute code with code interpreter inside Sandbox
from e2b_code_interpreter import Sandbox
with Sandbox.create() as sandbox:
sandbox.run_code("x = 1")
execution = sandbox.run_code("x+=1; x")
print(execution.text) # outputs 2
4. Check docs
