Get activities from Strava

I made integration with Strava, now it’s time to get activities from them. I want to get all of them because I need history for my bikes. Otherwise, I would probably be interested in only new ones.

For this case I’m going to create new endpoint - get_activities. This endpoint is going to do three things.

def get_activities(request)
  update_tokens

  activities = fetch_all_activities

  [200, {"content-type" => "application/json"}, [activities.to_json]]
end

First thing - update tokens. Tokens have a short lifetime so it’s nice to update them every time we are calling external API. Otherwise, users will have to authorize in Strava again.

def update_tokens
  response = @strava_oauth_client.oauth_token(
    refresh_token: StravaIntegration::Repository.new.get_refresh_token,
    grant_type: "refresh_token"
  )

  StravaIntegration::Repository.new.update_credentials(
    access_token: response.access_token, refresh_token: response.refresh_token
  )
end

Second thing is fetching all activities.

def fetch_all_activities
  client = Strava::Api::Client.new(access_token: StravaIntegration::Repository.new.get_access_token)

  page = 1
  all_activities = []

  loop do
    activities = client.athlete_activities(page: page)
    activities.each { |activity| all_activities << activity.to_h }
    break if activities.empty?

    page += 1
  end

  all_activities
end

The fourth thing is the return response, with all activities

[200, {"content-type" => "application/json"}, [activities.to_json]]

As you can see, there is nothing related to saving in database. It’s because I don’t have my own activities module yet. I’m going to do this in the next step, with my own rules, I want to convert Strava to something universal with the information that I need. But right now, getting activities from external API works fine. As always you can check my code on github
