Set up OAuth

log2viz uses OAuth to fetch your application’s logs. You can create a new OAuth client via the Heroku API:

curl -i -n -X POST \
-d "client[name]=myviz&client[redirect_uri]=http://localhost:5000/auth/heroku/callback" \
https://api.heroku.com/oauth/clients

HTTP/1.1 201 Created

{
  "id":"3f1057xxxxxxxxxxxxxxx”,
  "name":"myviz",
  "description":null,
  "redirect_uri":"http://localhost:5000/auth/heroku/callback”,
  "secret":"ac6f8a482c91b0540d8xxxxxxxxxxxxxxxxxxx”,
  "trusted":false
}

As well as view your existing clients:

curl -i -n -X GET https://api.heroku.com/oauth/clients

HTTP/1.1 200 OK

[
  {
    "id":"3f1057xxxxxxxxxxxxxxx”,
    "name":"myviz",
    "description":null,
    "redirect_uri":"http://localhost:5000/auth/heroku/callback”,
    "secret":"ac6f8a482c91b0540d8xxxxxxxxxxxxxxxxxxx”,
    "trusted":false
  },
  {
    ...
  }
]

In your application’s .env, set the HEROKU_ID and HEROKU_SECRET variables to those returned by the API.

Start the server

foreman start

And you’re done! Your app will be running at http://localhost:5000
