MicroSteemit on Wechat application - show account operations history

in #utopian-io5 years ago

New Features



MicroSteemit is developed based on the wechat micro application which is maintained by the tencent company.

wechat micro application is an application that doesn't need to be downloaded and installed. It implements the dream of "reach within reach", and users scan or search can open the micro application through the wechat application. It also reflects the idea of "running away", and users don't have to worry about installing too many apps. Micro Applications will be ubiquitous, readily available, without installing uninstall. Suitable for life service offline shops and non-new low-frequency conversion. The micro application can realize seven functions such as message notification, offline scan code and public number association. Among them, the user can realize the mutual jump between the wechat public account and the micro application through wechat association.

In a word , MicroSteemit is an application which can be used without downloading while chatting with friends in wechat easily. Just by scanning the MicroSteemit QR code can we commodiously surf on the steemit community.

New features

  • Show account related operations history

    Account operations history is always with a mass of data.To leave enough time for requesting to the server and dealing with related data , it is a good way to showing the loading current progress in the graph vividly. So I decide to use a circle loading progress to complete this feature .

    1.Firstly creating a canvas position with its unique ID


    2.Secondly before drawing , we should initial the canvas with setting its attribute on the onReady() function


    3.Add an arc path to the current path and draw clockwise

    cxt_arc.arc(100, 100, 96, 0, 2 * Math.PI, false);

    • Radius : 96

    • Green dot :Center of the circle(100,100)

    • Red dot : The starting point of curve (0)

    • Blue dot : The end point of curve (2 * Math.PI)

    4.Asynchronously showing the dynamic progress when loading account operations history

    Set interval per 100 ms to run animation() :

    setInterval(animation, animation_interval)

    endAngle = step * 2 * Math.PI / n + 1.5 * Math.PI;
    ctx.arc(x, y, radius, startAngle, endAngle, false);

    5.Dynamically setting the current progress below the graph

    that.setData({ circleProgress: ((step-1)*100/n).toFixed(0)})


    At the meantime , requesting for the account related operations

          url: 'https://api.steemjs.com/get_account_history?account=' + account+'&from=-1&limit=300',
          method: 'GET',
          success: function (res) {
            if (res.statusCode == '200') {
              var data = res.data;
              for (var d in data){
                var obj = new Object();
                var opDetail = data[d][1].op[1];
                var opCategory = data[d][1].op[0];
                var timestamp = data[d][1].timestamp;
                obj.category = opCategory;
                obj.detail = opDetail;
                obj.timestamp = timestamp;
          complete: function (res) {

    1.According to its format , save the operation category and timestamp and also the detail object into the operations array.

    that.setData({ operations: operations.reverse()})

    2.Because of the saved object detail instead of array , we should show both the keys and the values of the object

    <block wx:for="{{ operations }}" wx:for-index="operation-index" wx:for-item="operation">

    3.Now the data is got , next will be the UI setting .

    Create the child table under the main item :

    <view class='operation-detail-table'>
        <view class="table">
            <view class="row" wx:for="{{operation.detail}}" wx:for-index="index" wx:for-item="item">
              <view class="op-index">{{index}}</view>
                  <view class="op-item">{{item}}</view>

    4.Yeah , and show the different colors signifying the different categories.

    <view class="dot {{operation.category}}_dot"></view>

Proof of work done


  • Filter the account operations history by its timestamp and category .
  • Add showing dynamic coins price
  • Perfect the UI
