SteemThink-Use angular & steem API create steem blockchain-based sites
New Projects
What is the project about?
steemthink is a question and answer platform based on STEEM blockchain. The existing pc-side website has just started and completed the acquisition of the homepage data.
Technology Stack
I used angular as my front frame.And use Interactive Steem API to get the data from the blockchain
Roadmap
Complete the homepage of data acquisition, I will continue to develop the content page, and complete the comment and voting functions
How to contribute?
You can contribute to the project with utopian and github
As can be seen from the picture, the page has been from the block chain to get the latest articles under the utopian-io directory.
Below I will share with you how this page is completed, only for the angular and steem api to share.
Use steem API to get the latest data in the utopian-io directory
var app = angular.module('myApp', []);
app.controller('siteCtrl', function($scope, $http) {
$http({
method: 'GET',
url: 'https://api.steemjs.com/get_discussions_by_created?query={"tag":"utopian-io", "limit": "10"}'
}).then(function successCallback(response) {
$scope.lists = response.data;
}, function errorCallback(response) {
});
});
Use angular's http service to get data from the blockchain，the Request URL is
https://api.steemjs.com/get_discussions_by_created?query={"tag":"utopian-io", "limit": "10"}'
the method is GET
Use angular Create a module and Add controller
var app = angular.module('myApp', []);
app.controller('siteCtrl', function($scope, $http)
Format the reputation from json , use 2 part code
for (i=0; i<$scope.lists.length; i++ ) {
var author_reputation = this.change($scope.lists[i].author_reputation);
$scope.lists[i].author_reputation = author_reputation;
}
and
function change(reputation){
if (reputation == null) return reputation;
reputation = parseInt(reputation);
let rep = String(reputation);
const neg = rep.charAt(0) === "-";
rep = neg ? rep.substring(1) : rep;
const str = rep;
const leadingDigits = parseInt(str.substring(0, 4));
const log = Math.log(leadingDigits) / Math.log(10);
const n = str.length - 1;
let out = n + (log - parseInt(log));
if (isNaN(out)) out = 0;
out = Math.max(out - 9, 0);
out = (neg ? -1 : 1) * out;
out = out * 9 + 25;
out = parseInt(out);
return out;
};
Because the field value obtained by the official api is a string that needs to be formatted for normal display.
Here need to thank @stoodkev, For the format gave me a great help.

After the data is processed, we display it using angular ng-repeat

We also pay attention to peerquery.
Peerquery more like a platform for information aggregation, steemit the contents of the classification.
steemthink is a platform focused on providing knowledge sharing.
There are some differences in the orientation and development direction.
Okay. That's good to know.
Today I completed the production of 80% of the content page, but there are still some problems in the body field resolution. When I finish, I will continue to share with you.
The content page uses the angular routing function & passing parameters through the url.
Please look forward to my share, thanks again.
Your contribution cannot be approved yet. See the Utopian Rules. Please edit your contribution to reapply for approval.
I checked the README and I didn't find any commands to make it work or deploy it somewhere.
Do you have a test site for this? I want to try and check it myself. Can you please deploy this to heroku?
If I understood this project correctly, it's composed of a web app and a mobile app? What made you decide to put this into one github project? Wouldn't it be easier to maintain if you split them into two projects?
You may edit your post here, as shown below:
