prices-in-major-units - ESLint plugin rules

This rule disallows price values that look like they're in the smallest currency unit, since Medusa stores prices in major units.

Severity#

warn. This rule is enabled in the recommended preset.

What it Targets#

This rule targets price-like properties, such as amount, unit_price, or total. It reports values that look like cents, such as a value multiplied by 100, an identifier named with a cents suffix, or a large integer literal.

The following code is reported by the rule:

const item = { amount: price * 100 }

Instead, use the value in major units:

const item = { amount: price }

Why it's Important#

Medusa expects prices in major units, such as 19.99 rather than 1999. Passing a value in the smallest currency unit results in prices that are inflated by a factor of the currency's minor units.

Fixable#

This rule isn't auto-fixable.

Turn it Off#

To turn off this rule, set it to off in your ESLint configuration:

import { defineConfig } from "eslint/config"
import medusa from "@medusajs/eslint-plugin"

export default defineConfig([
  ...medusa.configs.recommended,
  {
    rules: {
      "@medusajs/prices-in-major-units": "off",
    },
  },
])

Or disable it for a single line using an inline comment:

// eslint-disable-next-line @medusajs/prices-in-major-units
const item = { amount: price * 100 }
