Build your first App
Build an App under 5 minutes.
This guide helps you in creating your first application with IndustryApps AppStore.
Before creating the application you need to complete the registration step as explained under Register developer account.

How to develop an application

There are no technology barriers for creating an application for IndustryApps platform. The application here is only to provide you a quick approach to create a simple hello world application and see them inside IndustryApps. It would give you a quick understanding on the business model.

​# Step 1 Creating node application

npm init -y

# Step 2 Implementing basic requirements

# Step 2.1 Adding Dependencies

npm install eureka-js-client express nodemon --save
  • eureka-js-client to implement registry sync
  • express as application server
  • nodemon to react with changes without reloading

# Step 2.2 Creating basic server and implementing application registry sync

'use strict';
​
const express = require('express');
const Eureka = require('eureka-js-client').Eureka;
const APPLICATION_CODE = process.env.APPLICATION_CODE;
const APP_REGISTRY_HOST = process.env.APP_REGISTRY_HOST;
const APP_REGISTRY_PORT = process.env.APP_REGISTRY_PORT;
const APP_HOST = process.env.APP_HOST;
const APP_PORT = process.env.APP_PORT;
const app = express();
​
// example configuration
const client = new Eureka({
// application instance information
instance: {
app: `${APPLICATION_CODE}`,
hostName: APP_HOST,
ipAddr: APP_HOST,
statusPageUrl: `http://${APP_HOST}:${APP_PORT}`,
vipAddress: `${APPLICATION_CODE}`,
port: {
$: APP_PORT,
'@enabled': 'true',
},
dataCenterInfo: {
'@class': 'com.netflix.appinfo.InstanceInfo$DefaultDataCenterInfo',
name: 'MyOwn',
},
registerWithEureka: true,
fetchRegistry: true,
},
eureka: {
// eureka server host / port
host: APP_REGISTRY_HOST,
port: APP_REGISTRY_PORT,
servicePath: '/eureka/apps/',
},
});
​
​
client.logger.level('debug');
client.start(error => {
console.log(error || 'NodeJS Started!');
app.get('/', (req, res) => {
res.sendFile(__dirname + '/index.html', err => console.log);
});
});
​
app.listen(APP_PORT, APP_HOST);
console.log(`Running on http://${APP_HOST}:${APP_PORT}`);
​

# Step 2.3 Adding theming and basic components

<html>
<head>
<title>Sample App</title>
<link href="/dam/public/iapp-ui-styles/v.1.0.0/main.css">
<script src="/dam/public/iapp-generics/v.1.0.1/iapp-generics.js"></script>
</head>
<body>
<iapps-require-module>
<iapps-module name="basic"></iapps-module>
</iapps-require-module>
<iapps-header-sidebar></iapps-header-sidebar>
<div class="content-area bg-grey">
<h1>Hello from sample app</h1>
</div>
</body>
</html>
Following urls /dam/public/iapp-ui-styles/v.1.0.0/main.css and/dam/public/iapp-generics/v.1.0.1/iapp-generics.js will be resolved when you access the application via local gateway.

# Step 3 Packing as Docker image

FROM node:carbon
​
# create the app directory for inside the Docker image
WORKDIR /usr/src/app
​
# install app dependencies from the package.json (and the package-lock.json)
COPY package*.json ./
​
RUN npm install
​
# bundle app source inside Docker image
COPY . .
​
# expose port 8080 to have it mapped by Docker daemon
EXPOSE 8080
​
# define the command to run the app (it's the npm start script from the package.json)
# npm start
CMD [ "npm", "start" ]

# Step 4 Access platform with credentials

When accessing the URL of the platform provided by the team you will find a screen like below.
When clicking on the menu item
you will be redirected to your app. Screenshot based on above snippet is given below.
