Creating Veery API NodeJS

Jan 24, 2017

http://veeryapinodejs.soupmode.com

---

edit dns.
create cname record:
hostname = veeryapinodejs
is an alias of = @

cd into /home/veery

mkdir Veery-API-NodeJS

cd into Veery-API-NodeJS

mkdir js

cd js

mkdir node_modules, although it might get automatically created later

create package.json

{
"name" : "Veery-API-NodeJS",
"version" : "1.0.0",
"dependencies" : {
"express" : "4.14.0",
"body-parser" : "1.16.0",
"html-entities" : "1.2.0",
"querystring" : "0.2.0"
}
}

unsure if i need all of those packages. i looked up the most recent package version numbers at https://www.npmjs.com

the command "npm install" will read the package.json file, create node_modules directory, and place the downloaded the packages listed in the json file in that directory.

within the same "js" directory, create dispatch.js

var express = require('express'),
bodyParser = require('body-parser'),
path = require('path'),

app = express();

app.use(bodyParser.urlencoded({ extended: true })); // parse application/x-www-form-urlencoded

app.get('/', function(req, res){
res.send('hello world');
});

app.listen(3002);

cd /etc/nginx/sites-available

create veeryapinodejs.soupmode.com

1. veeryapinodejs.soupmode.com-info

server {
listen 80;
server_name veeryapinodejs.soupmode.com;

location / {
default_type text/html;
error_page 404 = @fallback;
}

location @fallback {
proxy_pass http://veeryapinodejs.soupmode.com:3002;
}

}

ln -s /etc/nginx/sites-available/veeryapinodejs.soupmode.com /etc/nginx/sites-enabled/veeryapinodejs.soupmode.com

service nginx restart

forever start dispatch.js

more about forever commands:

usage: forever [start | stop | stopall | list] [options] SCRIPT [script options]

options:
start start SCRIPT as a daemon
stop stop the daemon SCRIPT
stopall stop all running forever scripts
list list all running forever scripts

forever list

in browser or with curl, access http://veeryapinodejs.soupmode.com

should see the plain text response: hello world

etc.

couchdb clients

1.
https://www.npmjs.com/package/couchdb

2.

3.
https://www.npmjs.com/package/couchdb-client

4. - the one that i chose to try first:

### Jan 26, 2017

created command prompt test script.

tried running but i received:

SyntaxError: Use of const in strict mode.

which is due to the use of const in the couchdbjs module and due to my server running and old version of node.

sudo npm cache clean -f
sudo npm install -g n
sudo n stable
sudo ln -sf /usr/local/n/versions/node/<VERSION>/bin/node /usr/bin/node

version=7.4.0

but when i ran node -v, i was still running the old version instead of v7.4.0 that i installed. the old version was v0.10.21

i tried whereis node which produced:

/usr/bin/node /usr/local/bin/node

both of those were version 7.4.0.

then i did "which node" which produced:
