title: Adding pattern parts
|
|
for: developers
|
|
about: Shows you how to add new parts to your pattern
|
|
---
|
|
|
|
Since the patterns parts are listed
|
|
in [the configuration file](/reference/config/), freesewing knows about
|
|
all the parts that belong to your pattern.
|
|
|
|
It expects that each pattern has its own draft method, that is called `draft`
|
|
followed by the capitalized name of the pattern part.
|
|
|
|
For example, if our pattern `Sorcha` has a part called `back`, you should
|
|
have a `draftBack` method. It's good practice to keep each part in its own
|
|
file, so create a file called `back.js`. Inside, you export your method
|
|
to draft this part:
|
|
|
|
```js
|
|
export default part => {
|
|
// Your part code here
|
|
|
|
return part
|
|
}
|
|
```
|
|
|
|
Then, in your `index.js` file, you import this file, and attach the
|
|
method to your pattern's prototype:
|
|
|
|
```js
|
|
import freesewing from "freesewing"
|
|
import plugins from "@freesewing/plugin-bundle"
|
|
import config from "../config"
|
|
// Parts
|
|
import draftBack from "./back"
|
|
|
|
// Create new design
|
|
const Sorcha = new freesewing.Design(config, plugins)
|
|
|
|
// Attach to pattern prototype
|
|
Sorcha.prototype.draftBack = part => draftBack(part)
|
|
```
