Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

默认表结构定义

数据模型

fibos_tokens 表

| 字段 | 类型 | 说明 | | --- | --- | --- | | id | int | 自增id | | token_name | text | 通证名 FO@eosio| | token_type | text | 通证类型(tradition:传统通证,tradition:智能通证) | | token_status | text | 通证状态(on:在线,off:销毁) | | created| Date | 通证创建时间 | | createdAt | Date | 记录创建时间 | | updatedAt | Date | 记录更新时间 | | creator_id | String | 通证创建者关联账号 |

fibos_tokens_action 表

| 字段 | 类型 | 说明 | | --- | --- | --- | | id | int | 自增id | | account_from_id | String | 交易发起账户 | | account_to_id | String | 交易目标账户 | | contract_action | String | 交易名称 | | token_from_id | int | 交易发起通证关联id | | token_to_id | int | 交易目标通证关联id| | transaction_id | int | 交易关联事务id| | global_sequence | int | 交易唯一标识 | | createdAt | Date | 记录创建时间 | | updatedAt | Date | 记录更新时间 |

查询示例

示例 server

const http = require('http');
const Tracker = require("fibos-tracker");

let port = 8080;

let DBconnString = process.env.DBconnString || 'mysql://root:[email protected]/fibos_chain';
Tracker.Config.DBconnString = DBconnString;

const tracker = new Tracker();
tracker.use(require("fibos-tokens"));

var svr = new http.Server(port, [
    (req) => { req.session = {} },
    {
        "/1.0/app": tracker.app
    }]);

svr.start();

以下所有查询都通过 graphql

业务场景-:

查询账号 「fibos」 的所有操作

const http = require('http');
http.post(`http://127.0.0.1:8081/1.1`, {
	headers: {
		'Content-Type': 'application/graphql'
	},
	body: `
		{
			find_fibos_tokens_action(
				order:"-id"
				where:{
					or:[{
						account_from_id: "fibos"
					},{
						account_to_id: "fibos"
					}]
				}
			){
				account_from{
					id
				}
				account_to{
					id
				}
				action{
					rawData
					transaction{
                          block{
                              status
                    }}
				}
			}
		}`
}).json();

解释:这条查询的含义为查询和账号 「fibos」相关的所有操作。 返回结果说明:

account_from->id:操作发起人
account_to->id:操作接受人
action->rawData:链上具体数据
action->transaction->block->status:当前交易状态(noirreversible:该笔交易不会被分叉,irreversible:该笔交易可能被分叉)

业务场景二:

查询账号 「fibos」的所有转账操作

const http = require("http");
http.post(`http://127.0.0.1:8081/1.1`, {
	headers: {
		'Content-Type': 'application/graphql'
	},
	body: `
		{
			find_fibos_tokens_action(
				order:"-id"
				where:{	
					or:[{
						account_from_id: "fibos"
					},{
						account_to_id: "fibos"
					}],
					contract_action:{
						in:["eosio.token/transfer","eosio.token/extransfer"]
					}
				}
			){
				account_from{
					id
				}
				account_to{
					id
				}
				action{
					rawData
					transaction{
                          block{
                              status
                    }}
				}
			}
		}`
}).json();

解释:索引条件说明:

contract_action -> in(["eosio.token/transfer","eosio.token/extransfer"]) FIBOS 中支持转账的方法为 eosio.token/transfer 和 eosio.token/extransfer
返回结果说明:
account_from->id:操作发起人
account_to->id:操作接受人
action->rawData:链上具体数据
action->transaction->block->status:当前交易状态(noirreversible:该笔交易不会被分叉,irreversible:该笔交易可能被分叉)
