The only transport provided now is HTTP(2). For most users the only change required is to swap `wss://` to `https://` in the address. If you run your own full node make sure to set the proper [CORS headers](https://en.wikipedia.org/wiki/Cross-origin_resource_sharing) if you plan to access it from a browser. --- Browser compatibility --------------------- [![Build Status](https://saucelabs.com/browser-matrix/jnordberg-dsteem.svg)](https://saucelabs.com/open_sauce/user/jnordberg-dsteem) Installation ------------ ### Via npm For node.js or the browser with [browserify](https://github.com/substack/node-browserify) or [webpack](https://github.com/webpack/webpack). ``` npm install dsteem ``` ### From cdn or self-hosted script Grab `dist/dsteem.js` from a [release](https://github.com/jnordberg/dsteem/releases) and include in your html: ```html ``` Or from the [unpkg](https://unpkg.com) cdn: ```html ``` Make sure to set the version you want when including from the cdn, you can also use `dsteem@latest` but that is not always desirable. See [unpkg.com](https://unpkg.com) for more information. Usage ----- ### In the browser ```html ``` See the [demo source](https://github.com/jnordberg/dsteem/tree/master/examples/comment-feed) for an example on how to setup a livereloading TypeScript pipeline with [wintersmith](https://github.com/jnordberg/wintersmith) and [browserify](https://github.com/substack/node-browserify). ### In node.js With TypeScript: ```typescript import {Client} from 'dsteem' const client = new Client('https://api.steemit.com') for await (const block of client.blockchain.getBlocks()) { console.log(`New block, id: ${ block.block_id }`) } ``` With JavaScript: ```javascript var dsteem = require('dsteem') var client = new dsteem.Client('https://api.steemit.com') var key = dsteem.PrivateKey.fromLogin('username', 'password', 'posting') client.broadcast.vote({ voter: 'username', author: 'almost-digital', permlink: 'dsteem-is-the-best', weight: 10000 }, key).then(function(result){ console.log('Included in block: ' + result.block_num) }, function(error) { console.error(error) }) ``` With ES2016 (node.js 7+): ```javascript const {Client} = require('dsteem') const client = new Client('https://api.steemit.com') async function main() { const props = await client.database.getChainProperties() console.log(`Maximum blocksize consensus: ${ props.maximum_block_size } bytes`) client.disconnect() } main().catch(console.error) ``` With node.js streams: ```javascript var dsteem = require('dsteem') var es = require('event-stream') // npm install event-stream var util = require('util') var client = new dsteem.Client('https://api.steemit.com') var stream = client.blockchain.getBlockStream() stream.pipe(es.map(function(block, callback) { callback(null, util.inspect(block, {colors: true, depth: null}) + '\n') })).pipe(process.stdout) ``` Bundling -------- The easiest way to bundle dsteem (with browserify, webpack etc.) is to just `npm install dsteem` and `require('dsteem')` which will give you well-tested (see browser compatibility matrix above) pre-bundled code guaranteed to JustWork™. However, that is not always desirable since it will not allow your bundler to de-duplicate any shared dependencies dsteem and your app might have. To allow for deduplication you can `require('dsteem/lib/index-browser')`, or if you plan to provide your own polyfills: `require('dsteem/lib/index')`. See `src/index-browser.ts` for a list of polyfills expected. --- *Share and Enjoy!* --- _Source: https://npm.io/package/dsteem · Machine-readable twin of the npm.io package page.
