Question 1

How to use log-symbols in async Node.js functions?

Accepted Answer

Simply import logSymbols and use it within your async function, such as console.log(logSymbols.success, 'Async task completed'). Ensure your terminal supports colors for the best experience, as it relies on terminal capabilities.

Question 2

log-symbols vs chalk for terminal output?

Accepted Answer

log-symbols is focused on providing predefined colored symbols for log levels, while chalk is a general-purpose library for styling terminal strings. Use log-symbols for quick log symbols, and chalk if you need more control over colors and styles in your output.

Question 3

Can I change the colors in log-symbols?

Accepted Answer

No, log-symbols has a fixed color scheme that cannot be changed without modifying the source code. If you need customizable colors, consider using a library like chalk alongside or instead for more flexibility.

Question 4

How to add custom symbols to log-symbols?

Accepted Answer

log-symbols does not support custom symbols out of the box. You would need to fork the repository or create your own object with symbols. For more flexibility, look at related libraries like 'figures' which might offer more options.

Question 5

Is log-symbols compatible with TypeScript?

Accepted Answer

Yes, log-symbols includes TypeScript definitions, so you can use it seamlessly in TypeScript projects. Import it as shown in the README, and the types should be automatically recognized without additional setup.

Question 6

log-symbols or figures for terminal symbols?

Accepted Answer

log-symbols is simpler and specifically for log levels with colors, while figures provides a wider range of Unicode symbols without colors. Choose log-symbols for colored log symbols, and figures if you need more symbol variety without color.

Question 7

How to test output with log-symbols in unit tests?

Accepted Answer

When testing, you can mock console.log or use libraries like 'sinon' to capture output. Since log-symbols outputs colored strings with ANSI codes, ensure your test environment handles these or mock the library to avoid color codes in test assertions.
