# Function: init()
|
|
|
|
> **init**(): `Promise`\<`void`\>
|
|
|
|
Defined in: [index.ts:60](https://github.com/acamarata/solar-spa/blob/3c848806ab852464d76baf7e3fc0ca58f5e42fd9/src/index.ts#L60)
|
|
|
|
Purpose: Pre-initialize the WASM module before the first spa() call.
|
|
Inputs: none
|
|
Outputs: Promise<void>; resolves when the module is ready
|
|
Constraints: Safe to call multiple times; subsequent calls return immediately.
|
|
If init() fails, the next call retries (failed promise is discarded).

|
## Returns
|
|
|
|
`Promise`\<`void`\>
|
|
|
|
Promise that resolves when the WASM module is initialized.
|
|
|
|
## Example
|
|
|
|
```ts
|
|
import { init, spa } from 'solar-spa';
|
|
await init(); // pay WASM startup cost at app boot
|
|
const result = await spa(new Date(), 40.7128, -74.0060); // no init overhead
|
|
```
