Visual Javascript

Create Kubernetes apps in minutes

Demo - A lightweight app builder for Kubernetes - https://yazz.com/app/homepage.html

• Build apps in minutes with drag and drop interface and code business logic in Javascript
• One click deploy to Docker or OpenShift
• Open source MIT license
• Runs in Docker on the cloud or locally
• Can be run as a Desktop app in Electron

Docker Quick start

1) Download and run Docker

2) Expose the Docker REST api on port 1234 with:

docker run -d -v /var/run/docker.sock:/var/run/docker.sock -p 127.0.0.1:1234:1234 bobrik/socat TCP-LISTEN:1234,fork UNIX-CONNECT:/var/run/docker.sock

3) Install and run the Visual Javascript IDE with:

docker run -p 80:80 -d zubairq/visualjs

4) Go to a browser and view Visual Javascript:

http://localhost

5) OPTIONAL - Run Postgres on docker on port 5432

docker run -e POSTGRES_PASSWORD=mysecretpassword -d -p 5432:5432 postgres

Remember, that if you want to talk to Postgres from a Docker app then you need to connect to the host:

host.docker.internal

Building Visual Javascript from source on Linux:

1) Install GIT from https://git-scm.com/downloads

2) Install Node.js 8.9 64 bit installer from https://nodejs.org/en/download/

3) From the command line get the Git repository

git clone https://github.com/zubairq/visualjs.git

4) Go to the Visual Javascript directory

cd visualjs

5) Install the NodeJS modules

sudo npm config set strict-ssl false    

sudo npm install --unsafe-perm

6) Run the Visual Javascript NodeJS application

node /src/electron.js --runapp homepage --nogui true --locked false

7) Create the "yazz" shell command to replace "node src/electron.js"

sudo npm link

Building Visual Javascript from source on Windows

1) Install GIT from https://git-scm.com/downloads

2) Install Node.js 8.9 64 bit installer from https://nodejs.org/en/download/

3) From the command line get the Git repository

git clone https://github.com/zubairq/visualjs.git

4) Go to the Visual Javascript directory

cd visualjs

5) Install the NodeJS modules

npm install

6) Run the Visual Javascript Electron application

electron .

OR run as Node.js application with browser based access

 node .\src\electron.js --runapp homepage --nogui true --locked false

Building Visual Javascript from source on Mac:

1) Install GIT from https://git-scm.com/downloads

2) Install Node.js 8.9 64 bit installer from https://nodejs.org/en/download/

3) From the command line get the Git repository

git clone https://github.com/zubairq/visualjs.git

4) Go to the Visual Javascript directory

cd visualjs

5) Install the NodeJS modules

npm install

6) Install SQlite3 for Electron

Copy
    node_macos64/node_sqlite3.noderename
to
    node_modules/sqlite3/lib/binding/node-v57-darwin-x64/node_sqlite3.node

7) Install Electron

npm install electron

8) Run the Visual Javascript Electron application

electron .

OR run as Node.js application with browser based access

 node src/electron.js --runapp homepage --nogui true --locked false

If Sqlite3 gives an error as it says it was compiled with a different version of NodeJS then recompile it

npm rebuild sqlite3  --update-binary

To build the Electron app:

1) Install SQlite3 for Electron

sudo npm install sqlite3 --build-from-source --runtime=electron --target=1.8.4 --dist-url=https://atom.io/download/electron (this step may not be needed on some platforms)

2) Run electron packager

Sudo electron-forge make

To build the Windows 10 Electron app you also need to:

1) Open Powershell in administator mode

2) Install Python 27

https://www.python.org/download/releases/2.7/

3) Set the Path variable in Powershell to find Python

$env:Path += ';d:\Python27\'

4) Install Microsoft Build Tools 2015

https://www.microsoft.com/en-us/download/details.aspx?id=48159

5) Install electron-forge

npm install -g electron-forge

6) Build the Windows Electron app with Electron Forge

electron-forge make

Command line options:

--help                 output usage information
--version              output the version number
--port                 Which port should I listen on? Default 80 or 3000 (if not run as sudo)
--host                 Server address of the central host (default is local machine IP address)
