Question 1

How do I install and use Putout in my project?

Accepted Answer

Install Putout via npm with 'npm i putout -D', then run it on directories like 'putout lib' to lint or add '--fix' to apply transformations. It requires Node.js 16 or higher and supports ESLint config files for easy setup.

Question 2

Putout or ESLint: which one is better for my code?

Accepted Answer

Choose Putout if you need automated code refactoring and transformations, like converting CommonJS to ESM. ESLint is better for teams that only want stylistic linting without code changes, as Putout is more aggressive in its fixes.

Question 3

Can Putout automatically fix syntax errors?

Accepted Answer

Yes, Putout can fix certain syntax errors automatically, as mentioned in its features. It uses built-in transformations to correct common issues, going beyond typical linting to improve code correctness.

Question 4

How to write a custom plugin for Putout?

Accepted Answer

Create a plugin by defining 'report' and 'replace' functions in a simple format, like the remove-debugger example. Plugins can be placed in a rules directory or published as npm packages, leveraging Putout's declarative syntax.

Question 5

Does Putout work with TypeScript and JSX files?

Accepted Answer

Yes, Putout supports TypeScript and JSX through its processors, allowing linting and transformation of .ts, .tsx, and .jsx files. You need to enable the TypeScript processor in configuration for full functionality.

Question 6

Is Putout safe to use on production codebases?

Accepted Answer

Use with caution: commit your code before running Putout with --fix, as recommended in the README, and review changes thoroughly. Its transformations are powerful but can be intrusive, so testing in a controlled environment is advised.
