deocoin-explorer v0.11.6

Deocoin Explorer

A Deocoin blockchain explorer web application service for Deocoincore Node using the Deocoin API.

Getting Started

1. Install nvm https://github.com/creationix/nvm
   We need Node 8. Nvm is a nice utility that allows easy switching between node versions.

   nvm i v8
   nvm use v8

2. Install mongo https://docs.mongodb.com/manual/tutorial/install-mongodb-on-ubuntu/

   Then open a Mongodb client window and create a user and database:

   use deocoin-api-livenet
   db.createUser(
     {
       user: "deocoin",
       pwd: "mynewpassword",
       roles: [ "readWrite", "dbAdmin" ]
     }
   )

3. Deocoin wallet installation

   Compile the addressindex branch and make sure you have ZMQ installed

   # Dependencies
   sudo apt-get install build-essential libtool autotools-dev automake pkg-config libssl-dev libevent-dev bsdmainutils git cmake libboost-all-dev
   sudo apt-get install software-properties-common
   sudo add-apt-repository ppa:bitcoin/bitcoin
   sudo apt-get update
   sudo apt-get install libdb4.8-dev libdb4.8++-dev
   # with ZMQ
   sudo apt-get install libzmq3-dev
   
   # If you want to build the Qt GUI:
   sudo apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler qrencode
   
   # Get the Deocoin wallet
   git clone https://github.com/deocoincore/deocoin
   cd deocoin
   git fetch origin
   git checkout addressindex
   
   # Note autogen will prompt to install some more dependencies if needed
   ./autogen.sh
   ./configure
   make -j2

4. Install deocoincore-node

   mkdir deocoinnode
   cd deocoinnode
   
   npm i deocoincore-node
   
   ./node_modules/.bin/deocoincore-node create mynode
   cd mynode
   
   ../node_modules/.bin/deocoincore-node install https://github.com/deocoincore/deocoin-insight-api.git#master
   ../node_modules/.bin/deocoincore-node install https://github.com/deocoincore/deocoin-explorer.git#master

5. Edit deocoincore-node.json to be similar to this (replace user with your username):

     {
       "network": "livenet",
       "port": 3001,
       "services": [
         "deocoind",
         "web",
         "deocoin-insight-api",
         "deocoin-explorer"
       ],
       "servicesConfig": {
         "deocoin-explorer": {
           "apiPrefix": "deocoin-insight-api",
           "routePrefix": "deocoin-explorer",
           "nodemapLink": "https://deocoin.org/en/nodemap"
       },
         "deocoin-insight-api": {
           "routePrefix": "deocoin-insight-api",
           "db": {
             "user": "deocoin",
             "password": "mynewpassword",
             "host": "localhost",
             "port": 27017,
             "database": "deocoin-api-livenet"
           },
           "erc20": {
             "updateFromBlockHeight": 5000
           }
         },
         "deocoind": {
           "spawn": {
             "datadir": "/home/user/.deocoin",
             "exec": "/home/user/deocoin/src/deocoind"
           }
         }
       }
     }

6. Configure Deocoin and sync the blockchain

   cd ~
   mkdir .deocoin
   cd .deocoin
   touch deocoin.conf

   Edit deocoin.conf:

   server=1
   whitelist=127.0.0.1
   logevents=1
   txindex=1
   addressindex=1
   timestampindex=1
   spentindex=1
   par=2
   onlynet=ipv4
   maxconnections=24
   zmqpubrawtx=tcp://127.0.0.1:28332
   zmqpubhashblock=tcp://127.0.0.1:28332
   rpcallowip=127.0.0.1
   rpcuser=user
   rpcpassword=password
   rpcport=8332
   addrindex=1
   reindex=1

   Run deocoind and sync the chain:

   cd ~/deocoin/src
   ./deocoind &

   You can check the progress of the sync with the deocoin-cli command. Kill the daemon once the chain is synchronized.

   ./deocoin-cli getInfo
   
   pkill deocoind

   You only need to run deocoind once with reindex=1 enabled. Once the chain is synced you can kill deocoind and comment the reindex setting in ~/.deocoin/deocoin.conf #reindex=1

7. Run Node (from the mynode folder):

   ../node_modules/.bin/deocoincore-node start

8. Open a web browser to http://localhost:3001/deocoin-explorer or http://localhost:3001/deocoin-insight-api

Development

To run Insight UI locally in development mode:

Install dependencies:

npm install

To compile and minify the web application's assets:

grunt compile

There is a convenient Gruntfile.js for automation during editing the code

grunt

Multi language support

Insight UI uses angular-gettext for multi language support.

To enable a text to be translated, add the translate directive to html tags. See more details here. Then, run:

grunt compile

This action will create a template.pot file in po/ folder. You can open it with some PO editor (Poedit). Read this guide to learn how to edit/update/import PO files from a generated POT file. PO file will be generated inside po/ folder.

If you make new changes, simply run grunt compile again to generate a new .pot template and the angular javascript js/translations.js. Then (if use Poedit), open .po file and choose update from POT File from Catalog menu.

Finally changes your default language from public/src/js/config

gettextCatalog.currentLanguage = 'es';

This line will take a look at any *.po files inside po/ folder, e.g. po/es.po, po/nl.po. After any change do not forget to run grunt compile.
