Dsteem代码修改后进行编译生成dsteem.js文件,该文件可引入HTML中,直接使用
npm install
安装相应依赖包
npm install terser --save
安装新的支持es6的编译时使用的包
将makefile中的uglifyjs
替换为terser
将
dist/dsteem.d.ts: $(SRC_FILES) node_modules
dts-generator --name dsteem --project . --out dist/dsteem.d.ts
sed -e "s@'dsteem/index'@'dsteem'@g" -i '' dist/dsteem.d.ts
替换为
dist/dsteem.d.ts: $(SRC_FILES) node_modules
dts-generator --name dsteem --project . --out dist/dsteem.d.ts
sed -i "s/'dsteem\/index'/'dsteem'/g" dist/dsteem.d.ts
运行npm run prepublishOnly
即可
Robust steem blockchain client library that runs in both node.js and the browser.
note As of version 0.7.0 WebSocket support has been removed. 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 if you plan to access it from a browser.
For node.js or the browser with browserify or webpack.
npm install dsteem
Grab dist/dsteem.js
from a release and include in your html:
<script src="dsteem.js"></script>
Or from the unpkg cdn:
<script src="https://unpkg.com/dsteem@^0.8.0/dist/dsteem.js"></script>
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 for more information.
<script src="https://unpkg.com/dsteem@latest/dist/dsteem.js"></script>
<script>
var client = new dsteem.Client('https://api.steemit.com')
client.database.getDiscussions('trending', {tag: 'writing', limit: 1}).then(function(discussions){
document.body.innerHTML += '<h1>' + discussions[0].title + '</h1>'
document.body.innerHTML += '<h2>by ' + discussions[0].author + '</h2>'
document.body.innerHTML += '<pre style="white-space: pre-wrap">' + discussions[0].body + '</pre>'
})
</script>
See the demo source for an example on how to setup a livereloading TypeScript pipeline with wintersmith and browserify.
With 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:
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+):
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:
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)
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!
