Question 1

What is a .prettierrc file?

Accepted Answer

A `.prettierrc` file (or related names like `.prettierrc.json`, `.prettierrc.yaml`, `prettier.config.js`) is used to configure Prettier, an opinionated code formatter. It allows you to define rules like print width, tab width, use of semicolons, etc.

Question 2

How do I use this viewer?

Accepted Answer

Click the "Open Local File" button to select your Prettier configuration file. Its content will be displayed with syntax highlighting based on its extension. If it's in JSON, YAML, or JS format, you might prefer our dedicated viewers for those formats for more specific handling. For `.prettierrc.toml`, use our .prettierrc.toml Viewer (link to /viewer/prettierrc-toml).

Question 3

Does this tool format code using these rules?

Accepted Answer

No, this viewer only displays the content of the configuration file. It does not apply Prettier formatting to your code.
