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.

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

2.

4. - the one that i chose to try first:
https://www.npmjs.com/package/couchdbjs

### 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.

http://askubuntu.com/questions/426750/how-can-i-update-my-nodejs-to-the-latest-version

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:
/root/local/bin/node

i did:
ln -sf /usr/local/n/versions/node/7.4.0/bin/node /root/local/bin/node

and now when i run "node -v", i get:
v7.4.0

and now my test script works.

test.js:

'use strict';

const Couchdbjs = require('couchdbjs');
const db = new Couchdbjs('mycouchdbname', cb);

var docinfo = db.getDoc('profile', cb);
var json_str = JSON.stringify(docinfo);

function cb (err, data) {
if (err) console.error(err);
else console.log(data); // data is array of uuids
}

json=
