크리 keu.li

keu.li lets users set up a simple page with social media links so that just one link can be shared to share all the links :) (exactly like linktree).

Configuration

Runtime variables

Update config/sys.config with database credentials.

nginx

Assuming the node is running and listening on 127.0.0.1:3000, and nginx is set up and running.

/etc/nginx/sites-available/default is symlinked to /etc/nginx/sites-enabled/default. No need to directly modify /etc/nginx/nginx.conf, include /etc/nginx/sites-enabled/*; will include the configs in sites-available/default.

server {
        ...
        location / { # Comment out the try_files line and add the proxy lines.
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                # try_files $uri $uri/ =404;
                proxy_pass http://127.0.0.1:3000;

                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header X-Forwarded-Proto $scheme;
        }
}

Release

<bin>/keuli restart should automatically upgrade if the new version was set in rebar.config and .app.src in the release compilation.

$ ./rebar3 release
$ ./_build/default/rel/keuli/bin/keuli restart

If not running, spin up the app in the background with <bin>/keuli daemon

$ ./_build/default/rel/keuli/bin/keuli daemon

Build

$ rebar3 compile

./rebar3 compile
./rebar3 release
./rebar3 run

Run in prod:

<in keuli folder>./_build/default/rel/keuli/bin/keuli daemon

Dev

local ssh dev

sshfs -o allow_other,default_permissions,IdentityFile=<absolute path (~ expands to remote fs)>/.ssh/id_rsa root@<ip address>:/ ~/dev/mnt/droplet
umount root@<ip address>:/

Data

CREATE TABLE IF NOT EXISTS users (
  id SERIAL PRIMARY KEY,
  create_time TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
  modify_time TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
  username VARCHAR(255),
  display_name VARCHAR(4095),
  display_image_url VARCHAR(4095),
  email VARCHAR(255),
  email_is_verified BOOLEAN DEFAULT FALSE,
  fields JSON,
  UNIQUE(username)
)

INSERT INTO users (username, email, fields) VALUES ('name', 'example@email.com', '{"links":[{"url":"https://instagram.com/name","name":"ig"},{"url":"https://twitch.tv/name","name":"twitch"}]}')

Running Dev Server on Production Node

Rename the apps/keuli directory to apps/keuli2, modify the following files, and then run on a different port like PORT=1337 ./rebar3 run.

+++ b/rebar.config
