### Interacting with contracts in Javascript
|
|
|
|
Embark will automatically take care of deployment for you and set all needed JS bindings. For example, the contract below:
|
|
|
|
```
|
|
// app/contracts/simple_storage.sol
|
|
|
|
contract SimpleStorage {
|
|
uint public storedData;
|
|
|
|
function SimpleStorage(uint initialValue) {
|
|
storedData = initialValue;
|
|
}
|
|
|
|
function set(uint x) {
|
|
storedData = x;
|
|
}
|
|
function get() constant returns (uint retVal) {
|
|
return storedData;
|
|
}
|
|
}
|
|
```
|
|
|
|
Will automatically be available in Javascript as:
|
|
|
|
```
|
|
// app/js/index.js
|
|
|
|
import SimpleStorage from 'Embark/contracts/SimpleStorage';
|
|
|
|
SimpleStorage.methods.set(100).send();
|
|
SimpleStorage.methods.get().call().then(function(value) { console.log(value) });
|
|
SimpleStorage.methods.storedData().call().then(function(value) { console.log(value) });
|
|
```
|
|
