Where 100 KB matters
A 102,400-byte file that sits exactly on the default request-body limit of Express. These are the default limits a file of this size is useful for testing:
| System | Limit | Note |
|---|---|---|
| Express body parsers | 100 KB (102,400 bytes) by default | A request body of exactly this size passes; anything larger returns 413 Payload Too Large. |
| Gmail message clipping | About 102 KB of HTML | Longer messages are truncated behind a "view entire message" link. |
| Amazon DynamoDB items | 400 KB per item | 100 KB fits; the 500 KB sample does not. |
Use this file for
- Checking email size handling
- Loading datasets for machine-learning experiments
- Testing bulk import endpoints
Testing notes for JSONL
- A blank line or a trailing comma on any line breaks strict readers, so decide how your importer treats them.
- Passing the whole file to a standard JSON parser fails, because the file as a whole is not one JSON value.
