OAuth login

class OAuthLogin {
static let shared = OAuthLogin()
let baseURL = "https://your-auth-server.com"
let clientID = "your-client-id"
let clientSecret = "your-client-secret"

Problem

I have two Github accounts: oanhnn (personal) and superman (for work). I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).

Solution

Use ssh keys and define host aliases in ssh config file (each alias for an account).

How to?

  1. Generate ssh key pairs for accounts and add them to GitHub accounts.

List of all countries with their 2 digit codes (ISO 3166-1)
[{
"Code": "AF",
"Name": "Afghanistan"
}, {
"Code": "AX",
"Name": "Åland Islands"
}, {
"Code": "AL",
"Name": "Albania"
}, {
#server side:
#server live directory: /var/www/domain.com
#server repository: /var/repo/site.git
1. clone project from git/bitbucket into /var/www/domain.com or init the folder by "git init".
2. go to /var/repo/site.git and init the folder as git bare
$git init --bare
--bare means that our folder will have no source files, just the version control.
