<h1 id="apipromise-examples">ApiPromise Examples</h1>
|
|
<p>Here you will find a list of examples that takes you through the basics of connecting to a local node, retrieving data from the Node and chain and execute transactions on the chain. It uses the [[ApiPromise]] interface.</p>
|
|
<h2 id="prerequisites">Prerequisites</h2>
|
|
<p>For the following examples, you need a local node. It is usually convenient testing with:</p>
|
|
<pre><code>substrate --dev
|
|
</code></pre><h2 id="running-the-examples">Running the examples</h2>
|
|
<p>From each folder, run <code>yarn</code> to install the required dependencies and then run <code>yarn start</code> to execute the example against the running node.</p>
|
|
<h2 id="development-accounts">Development accounts</h2>
|
|
<p>Some of the examples use the following accounts:</p>
|
|
<ul>
|
|
<li>Alice: <code>5GoKvZWG5ZPYL1WUovuHW3zJBWBP5eT8CbqjdRY4Q6iMaDtZ</code></li>
|
|
<li>Bob: <code>5Gw3s7q4QLkSWwknsiPtjujPv3XM4Trxi5d4PgKMMk3gfGTE</code></li>
|
|
</ul>
|
|
<p>Those accounts are easy to add if you don't have/see them. The seed of Alice's account is <code>Alice␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣</code> and the seed of Bob is... well you guess...</p>
|
|
<p>NOTE: Note the spaces padding Alice's key up to 32 chars.</p>
