Question 1

How to use YAML instead of JSON with conf?

Accepted Answer

Use the serialize and deserialize options with a YAML library like js-yaml. Set fileExtension to 'yaml' and provide custom functions to handle YAML parsing and stringifying, as shown in the FAQ section.

Question 2

Conf vs configstore: which is better for Node.js config?

Accepted Answer

Conf is the refined successor to configstore, with better cross-platform support and fewer permission issues. It stores config in system default directories, while configstore uses ~/.config, which can cause problems on macOS and Windows.

Question 3

Can conf handle multiple processes writing to config?

Accepted Answer

No, conf explicitly does not support multiple processes writing to the same store. It's designed for single-process scenarios, though watch mode can monitor changes for read-only multi-process use.

Question 4

Is conf's encryption secure for storing passwords?

Accepted Answer

No, the encryption is for obscurity only, not security. The README cautions that encryption keys are easily found in plain-text apps, so it's not suitable for sensitive data like passwords.

Question 5

How to implement versioned config migrations with conf?

Accepted Answer

Use the migrations option with version keys and handler functions. Specify projectVersion and define steps for each version or semver range, but note that this feature has known bugs and limited support.

Question 6

What are the performance implications of using conf for large configs?

Accepted Answer

Performance degrades with large data because conf reads and writes the entire JSON file on every change. It's best suited for small-scale data like user settings, not for large datasets.
