Library to provide client interface for Strava REST API(v3) in lua language

This project is maintained by akshaynathr


luastrava is a Lua library for Strava API version 3.

Getting started

luastrava can be installed using luarocks.

    luarocks install luastrava

Importing the library and creating a new client

    local strava = require('luastrava.client').Client
    local client=strava:new()

Authentication and Authorization with Strava API

To retrieve data about athletes and activities from Strava API, you will need authorization to do so.Refer Strava official documentation for the detailed description about OAuth2 protocol used by Strava for authentication.

Requesting Authorization

The luastrava.client.Client class provides luastrava.client.Client:authorization_url() method to generate authorization URL. This link opens the login page of strava which can be used by the user to grant permissions and access to the user’s account data.

local strava=require('luastrava.client').Client
local client=strava:new()
local url=client:authorization_url{client_id=CLIENT_ID,redirect_uri='http://localhost/auth',scope='write'}

For development , localhost or can be used as redirect host.

local url=client:authorization_url{client_id=CLIENT_ID, 

Example from lapis based web app is given below

 app:get("/", function(self) 
  --create authorization url  
  local url=client:authorization_url{client_id=client_id,
  redirect_uri='http:// localhost:8080/auth',scope='write'} 

  --redirect to the url 
      return {redirect_to=url} 

The link can be used to gain permission rights from the user.In the URL handler /authorization specified as redirect_uri, a temporary code is sent back from strava server. This temporary code needs to be exchanged for user’s token from Strava

   local code=self.params.code --Fetch the code sent via url parameter
   client:exchange_code_for_token(client_id,client_secret,code) --fetch token

  self.session.token=client:get_access_token() -- token is saved in session 

   return "Authorized token=".. client:get_access_token() --Display the token  as a proof for authorization. 

The resulting access_token must be saved for later use. In the above web app the token is saved in session.The token is valid till the access is revoked by user.

Using the token the data from Strava API can be retrieved.

local strava=require('luastrava.client').Client
local client=strava:new()
local athlete=client:get_athlete()

set_access_token function

luastrava.client.Client:set_access_token function is used to set the stored token to client object


get_access_token function

luastrava.client.Client:get_access_token retreives the token set for a client.Returns error if token is not set

local token= client:get_access_token()
