Configuration

Full documentation on how to create a Prettier configuration can be found in Prettier docs.

Configuration could be set via either:

• A .prettierrc file, written in YAML or JSON, with optional extensions: .yaml/.yml/.json/.json5/.js/.cjs/.mjs/.ts/.mts/.cts
• A prettier.config.(js|cjs|mjs|ts|cts|mts) file that exports an object
• A prettier key in the project's package.json file

The following examples show how to integrate predefined configuration in project:

• Via prettier.config.mts file:

export { default } from "@szum-tech/prettier-config";

Configurations also could be used to extends:

import { type Config } from "prettier";
import szumTechPrettierConfig from "@szum-tech/prettier-config";

export default {
  ...szumTechPrettierConfig,
  semi: false
} satisfies Config;

• Via prettier.config.mjs file:

export { default } from "@szum-tech/prettier-config";

Configurations also could be used to extends:

import szumTechPrettierConfig from "@szum-tech/prettier-config";

/**
 * @type {import("prettier").Config}
 */
export default {
  ...szumTechPrettierConfig,
  semi: false
};

• Via prettier.config.cjs file:

module.exports = require("@szum-tech/prettier-config");

OR extend configuration:

const szumTechPrettierConfig = require("@szum-tech/prettier-config");

/**
 * @type {import("prettier").Config}
 */
module.exports = {
  ...szumTechPrettierConfig,
  semi: false
};

• Via prettier key in the project's package.json file:

{
  "prettier": "@szum-tech/prettier-config"
}

• Via .prettierrc file:

"@szum-tech/prettier-config"

[!TIP] You can ignore files by adding it to .prettierignore.

💻 Scripts

Suggested scripts you can add to package.json file:

{
  "scripts": {
    "prettier:check": "prettier --check .",
    "prettier:write": "prettier --write ."
  }
}
