json-stringify-nice

This is a lightweight wrapper around JSON.stringify that provides consistent, readable output by sorting keys and enforcing 2-space indentation by default. In practice, it's useful for generating config files, commit-friendly diffs, and logs where human readability matters. The deterministic key ordering is particularly valuable for version control.

From a security perspective, json-stringify-nice has minimal attack surface since it's essentially a thin layer over native JSON.stringify. It doesn't introduce custom parsing logic or eval-based operations. The package has no dependencies, which is excellent for supply chain risk management - there's literally nothing to audit beyond the 50 lines of code. However, like JSON.stringify itself, it doesn't sanitize output for log injection or handle circular references gracefully (throws TypeError).

The main limitation is that it's purely a formatting tool. You still need to handle sensitive data filtering yourself before stringification. It won't prevent accidentally logging secrets or PII, and error messages from circular references can expose object structure. For production logging, pair it with explicit sanitization layers.

This is a straightforward wrapper around JSON.stringify that adds deterministic key sorting and consistent formatting. In practice, it's a set-it-and-forget-it utility that does exactly what it promises—nothing more, nothing less. The implementation is transparent and easy to audit, which matters when you're serializing data.

From a security perspective, the library has minimal attack surface. It doesn't attempt custom parsing or complex transformations that could introduce vulnerabilities. The sorted key output is particularly useful for generating consistent hashes or diffs of configuration objects. One caveat: it uses the standard JSON.stringify replacer/space parameters under the hood, so you still need to be mindful of circular references and non-serializable values that could throw exceptions.

The main limitation is that error handling is inherited directly from native JSON.stringify—you'll get the same cryptic errors for circular structures or BigInt values. For logging and config file generation where deterministic output matters, it's been reliable across Node versions without compatibility issues.

This is a thin wrapper around JSON.stringify that adds deterministic key sorting and sensible formatting defaults. In practice, it's useful for generating human-readable config files, git-friendly output, and debug logs. The code is simple enough to audit in minutes—it's essentially a replacer function with object key sorting logic.

From a security perspective, it's low-risk. No dependencies means zero supply chain exposure, which is refreshing. It doesn't introduce serialization vulnerabilities beyond what JSON.stringify already has, and there's no custom parsing that could be exploited. The predictable output format means no surprises when serializing sensitive data, though you still need to handle filtering secrets yourself.

The main limitation is it's purely cosmetic—it won't protect you from circular references, BigInt serialization, or prototype pollution. Error handling is basic, relying entirely on JSON.stringify's built-in throws. For logging and config generation where you control the input, it does exactly what it promises with minimal complexity.
