This PR includes documentation that preps for v2 docs (but doesn't introduce new docs). _Note: The number of file changes in the PR is due to find-and-replace within the `references` which is unavoidable. Let me know if I should move it to another PR._ ## Changes - Change Medusa version in base OAS used for v2. - Fix to docblock generator related to not catching all path parameters. - Added typedoc plugin that generates ER Diagrams, which will be used specifically for data model references in commerce modules. - Changed OAS tool to output references in `www/apps/api-reference/specs-v2` directory when the `--v2` option is used. - Added a version switcher to the API reference to switch between V1 and V2. This switcher is enabled by an environment variable, so it won't be visible/usable at the moment. - Upgraded docusaurus to v3.0.1 - Added new Vale rules to ensure correct spelling of Medusa Admin and module names. - Added new components to the `docs-ui` package that will be used in future documentation changes.

# ITaxService
|
|
|
|
## Overview
|
|
|
|
A tax provider is used to retrieve the tax lines in a cart. The Medusa backend provides a default `system` provider. You can create your own tax provider,
|
|
either in a plugin or directly in your Medusa backend, then use it in any region.
|
|
|
|
A tax provider class is defined in a TypeScript or JavaScript file under the `src/services` directory and the class must extend the
|
|
`AbstractTaxService` class imported from `@medusajs/medusa`. The file's name is the tax provider's class name as a slug and without the word `Service`.
|
|
|
|
For example, you can create the file `src/services/my-tax.ts` with the following content:
|
|
|
|
```ts title="src/services/my-tax.ts"
|
|
import {
|
|
AbstractTaxService,
|
|
ItemTaxCalculationLine,
|
|
ShippingTaxCalculationLine,
|
|
TaxCalculationContext,
|
|
} from "@medusajs/medusa"
|
|
import {
|
|
ProviderTaxLine,
|
|
} from "@medusajs/medusa/dist/types/tax-service"
|
|
|
|
class MyTaxService extends AbstractTaxService {
|
|
async getTaxLines(
|
|
itemLines: ItemTaxCalculationLine[],
|
|
shippingLines: ShippingTaxCalculationLine[],
|
|
context: TaxCalculationContext):
|
|
Promise<ProviderTaxLine[]> {
|
|
throw new Error("Method not implemented.")
|
|
}
|
|
}
|
|
|
|
export default MyTaxService
|
|
```
|
|
|
|
---
|
|
|
|
## Identifier Property
|
|
|
|
The `TaxProvider` entity has 2 properties: `identifier` and `is_installed`. The `identifier` property in the tax provider service is used when the tax provider is added to the database.
|
|
|
|
The value of this property is also used to reference the tax provider throughout Medusa. For example, it is used to [change the tax provider](https://docs.medusajs.com/modules/taxes/admin/manage-tax-settings#change-tax-provider-of-a-region) to a region.
|
|
|
|
```ts title="src/services/my-tax.ts"
|
|
class MyTaxService extends AbstractTaxService {
|
|
static identifier = "my-tax"
|
|
// ...
|
|
}
|
|
```
|
|
|

## Methods
|
|
|
|
### getTaxLines
|
|
|
|
This method is used when retrieving the tax lines for line items and shipping methods.
|
|
This occurs during checkout or when calculating totals for orders, swaps, or returns.
|
|
|
|
#### Example
|
|
|
|
An example of how this method is implemented in the `system` provider implemented in the Medusa backend:
|
|
|
|
```ts
|
|
// ...
|
|
|
|
class SystemTaxService extends AbstractTaxService {
|
|
// ...
|
|
|
|
async getTaxLines(
|
|
itemLines: ItemTaxCalculationLine[],
|
|
shippingLines: ShippingTaxCalculationLine[],
|
|
context: TaxCalculationContext
|
|
): Promise<ProviderTaxLine[]> {
|
|
let taxLines: ProviderTaxLine[] = itemLines.flatMap((l) => {
|
|
return l.rates.map((r) => ({
|
|
rate: r.rate || 0,
|
|
name: r.name,
|
|
code: r.code,
|
|
item_id: l.item.id,
|
|
}))
|
|
})
|
|
|
|
taxLines = taxLines.concat(
|
|
shippingLines.flatMap((l) => {
|
|
return l.rates.map((r) => ({
|
|
rate: r.rate || 0,
|
|
name: r.name,
|
|
code: r.code,
|
|
shipping_method_id: l.shipping_method.id,
|
|
}))
|
|
})
|
|
)
|
|
|
|
return taxLines
|
|
}
|
|
}
|
|
```
|
|
|
|
