test assigment

Short coding exercise as part of interview process - please use this repo to commit all of your work. Additional question may be provided via issues to this repo. Good luck and have fun! :)

Create HTTP Rest API:

• Use echo or gin for web handler
• Implement login endpoint with JWT token, and simple middleware that checks header for 'Authorization: Bearer %jwt_token%' in each request. Otherwise return 403 and json struct with error
• Implement endpoint that will use Facebook as OAuth2 provider
  • Implement authorize and create local user feature, using data from FB. Newly created user should be issued jwt token
  • For already existing users implement login feature.
• Log each request including status code
• Implement persistence with MySQL and Gorm (https://github.com/jinzhu/gorm)
• Use Goose or other tool of choice for DB migration (https://bitbucket.org/liamstask/goose)
• Implement save endpoint for Task object
• Implement update endpoint for Task object
• Implement get endpoint for Task object
• Implement delete endpoint for Task object (just update IsDeleted field)
• Use CORS (reply with header Access-Control-Allow-Origin: *)
• Add support for OPTION HTTP method for each endpoints
• Configure daemon over simple JSON config. Specify path as process flag for daemon. Required params: ListenAddress, DatabaseUri.
• Put in comments below description of taken architectural decisions

Task:

type Task struct {
    Id          int64
    Title       string
    Description string
    Priority    int
    CreatedAt   *time.Time
    UpdatedAt   *time.Time
    CompletedAt *time.Time
    IsDeleted   bool
    IsCompleted bool
}
