Dependencies

This project requires NodeJS (version >= 14.3), and MongoDB (version >= 4.2.9). If you prefer to use a remote database, cloud MongoDB for instance, you just need to install NodeJS on your machine. Other deps will be download on next step.

Developers

You will need codeclimate installed on your machine. In order to do that, you will have to install docker before.

Install engines (may take a while to finish and need sudo):

codeclimate engines:install

You can run it with (may need sudo):

npm run codeclimate

Setup

Install deps:

npm i

Create a .env file and set these variables:

APPPORT=<port where the API will run>
ADDRESSDB=<address where your database is running>
USERDB=<database user>
PASSDB=<database password>
NAMEDB=<database name>
PARAMSDB=<database extra params for connection string>
FRONTENDADDRESS=<address where front-end server is listening. ex:localhost:8080>
HTTPSKEYFILE=<path to your ssl key file (will be generated on next step)>
HTTPSCERTFILE=<path to your ssl cert file (will be generated on next step)>
JWTDEVTOKEN=<any jwt token to bypass auth in dev env. THIS MUST NOT BE SET IN PROD>
SECRETKEYHMAC=<any random string to be used as secret for HMAC on JWT>
SALTROUNDS=<number of rounds to bcrypt>
VIMEO_CLIENTID=<Vimeo clientid>
VIMEO_CLIENTSECRET=<Vimeo client secret>
VIMEO_ACCESSTOKEN=<Vimeo access token>

After running seed, you should have a user with email test@test.com and password 123456. This user can be used to test logged API accesses.

Seed dev database:

npm run dev-seed

Create a .env-test file and set the same variables you have at .env, but pointing to another database (this will be used just by automated tests).

Seed test database:

npm run dev-test

SSL/TSL config (dev/staging)

This config is important to have an HTTPS environment for devs.

Become a Certificate Authority

Generate private key

openssl genrsa -des3 -out myCA.key 2048

Generate root certificate

openssl req -x509 -new -nodes -key myCA.key -sha256 -days 825 -out myCA.pem

Create CA-signed certs

Create a variable to ease next steps

NAME=localhost

Generate a private key

openssl genrsa -out $NAME.key 2048

Create a certificate-signing request

openssl req -new -key $NAME.key -out $NAME.csr

Create a config file for extensions

touch $NAME.ext

Set these variables in that recently created file

authorityKeyIdentifier=keyid,issuer
basicConstraints=CA:FALSE
keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
subjectAltName = @alt_names
[alt_names]
DNS.1 = localhost
IP.1 = 127.0.0.1

Create(finally 🙄) the signed certificate

openssl x509 -req -in $NAME.csr -CA myCA.pem -CAkey myCA.key -CAcreateserial -out $NAME.crt -days 825 -sha256 -extfile $NAME.ext

Check if everything went fine

openssl verify -CAfile myCA.pem -verify_hostname $NAME $NAME.crt

Now import your CA file on your browser

Import myCA.pem as an Authority in your Chrome settings (Settings > Manage certificates > Authorities > Import)

Setup NGinX as reverse proxy

===

This section is important JUST IF you want to have your dev environment mirroring production environment. Otherwise you can just run a separate server to frontend with http-server, for instance

===

Ubuntu/Debian based distros

Just set up run permissions on script and run it

sudo chmod +x ./nginx_install.sh
sudo ./nginx_install.sh

Other environments

• Install NGinX on last available version
• Create a config file with following contents

server {
    server_name _;
    listen <host address>:443 ssl;
    ssl_certificate     <path to your SSL/TLS certificate file>;
    ssl_certificate_key <path to your SSL/TLS key file>;
    ssl_session_timeout 30m;
    ssl_session_cache   shared:SSL:400k;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    server_tokens off;
    charset utf-8;

    gzip on;
    gzip_min_length 0;
    gzip_proxied any;
    gzip_types text/html text/plain text/css text/javascript application/javascript application/x-javascript application/json image/svg+xml image/gif, image/png, image/jpeg image/webp;

    location / {
            proxy_pass https://<host address>:<host port>;
            proxy_http_version 1.1;
            proxy_set_header Upgrade \$http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_set_header Host \$host;
            proxy_cache_bypass \$http_upgrade;
    }

    location ~* ^.+\.(html|css|js|pdf|jpg|jpeg|png|svg) {
        root <path to your frontend public dir>;
    }

    location ~* ^\/?$ {
        root <path to your frontend public dir>;
        try_files /index.html =404;
    }

    location / {
        root <path to your frontend public dir>;
        try_files $uri.html $uri $uri/index.html $uri/ =404;
    }
}

• Reload NGinX

sudo nginx -s reload

Database seeding options

Force seed

By default, if a collection has any documents, it won't be seeded. If you want to force it, use the following.

For dev environment

npm run dev-seed -- --forceseed

For test environment

npm run test-seed -- --forceseed

Force drop

If you want to seed a database from scratch it is possible to drop collections before seeding.

For dev environment

npm run dev-seed -- --forcedrop

For test environment

npm run test-seed -- --forcedrop

Run API server

Development environment:

npm run dev

Run Tests

npm test

New seeds

If you are creating a new entity, it is very likely you want to seed a new collection. The place for it is models/db/seeds.js.

Logs

Logs are kept at /logs. You can check log rules at ./logger.js.

!! Logs are not rotated in dev env. Watch it !!

Production Environment

If you need instructions to create a new production server, you might want to have a look here.
