Build outputs

The package ships three builds plus types, selected automatically via the exports map:

File	Format	Used by
dist/index.mjs	ESM	import (bundlers, Node ESM, edge, Deno)
dist/index.js	CommonJS	require (Node CJS)
dist/steem.min.js	minified IIFE	<script> / CDN (global steem)
dist/index.d.ts	TypeScript declarations	editors / tsc

Import styles

// ESM — default import (the full steem object)
import steem from '@blazeapps/steem';

// ESM — named imports (tree-shakeable)
import { api, broadcast, auth } from '@blazeapps/steem';

// CommonJS
const steem = require('@blazeapps/steem');

Browser via CDN

<script src="https://cdn.jsdelivr.net/npm/@blazeapps/steem/dist/steem.min.js"></script>
<script>
  steem.api.getAccounts(['ned', 'dan'], function (err, accounts) {
    console.log(err, accounts);
  });
</script>

TypeScript

Types are bundled — no @types/... package needed. See the TypeScript guide.

import steem from '@blazeapps/steem';
const [account] = await steem.api.getAccountsAsync(['ned']); // fully typed
