ASIDE.IO is A Salesforce IDE that is fast, free, and easy to use. It is full-featured and supports the entire Salesforce development cycle from writing code, to running unit tests, querying/managing data, and deploying the resulting application. There is no download required to start using ASIDE.IO, it lives in the cloud as a web app, and is happy to be up there.

Getting Started

This is a guide for someone looking to contribute to or modify ASIDE. If you want to spin up a new instance of ASIDE and aren't interested in it's source code, read this instead.

In order to use this code, you will either need to run it locally or as a Heroku app. The steps below describe both processes.


To run ASIDE locally you will need:

  • Ruby 2.5.7
  • Bundler
  • A Salesforce Org that you're admin in
  • A Heroku account

Running Locally

First, create a Heroku app, visit for instructions.

$ mkdir aside-deploy-example
$ cd aside-deploy-example
$ git init
$ heroku apps:create aside-deploy-example

Put ASIDE's source code in the directory you just created. Now you should be ready to run ASIDE locally. Execute the command below which will create a web server running ASIDE.

$ heroku local

Now open your internet browser of choice, and navigate to:

http://<my ip address>:5000/login

...And now you're running your own instance of ASIDE!

Logging In

You'll probably want to be able to get past the login page, and the usual login buttons aren't going to work for that, due to how the OAuth is configured. However, you can use the "frontdoor" login endpoint to get in. To use the frontdoor login, you will need the org id of the org you want to log into, your user id, the instance name (e.g. na12), the endpoint type (login for production/developer edition, test for sandboxes), and have an api session id.

The org id and instance name both appear on the "Company Information" screen (setup -> Company Information).

Your user id is accessible from the url of your user detail page.

The endpoint type is just a static string value. "login" for production and developer edition orgs, and "test" otherwise.

Getting an API session id is slightly more complicated. You can obtain one by logging into ASIDEs backend from irb. Try the following series of commands. The login endpoint should be something like or

$ irb
2.5.7 :001 > require './D3VController'
2.5.7 :002 > ctrl ='<username>', '<password>', '<security token>', '<login endpoint>')

When the second command is successful it outputs a block of information which includes the session id. The session id is found in the @session_id parameter.

With this information you can use the frontdoor login. Visit the following url in your browser when heroku local is running.

http://<my ip address>:5000/frontdoor?ins=<instance name>&oid=<org id>&uid=<user id>&end=<endpoint type>&sid=<session id>
  • <instance name> is from the Company Information screen. e.g. na13
  • <org id> is the id of the org you are trying to log into
  • <user id> is the id of the user you are trying to login as
  • <endpoint type> is login or test depending on the org type
  • <session id> is the string of characters you obtaining from irb

When successful, you should be at ASIDE's main screen, same as if you had used the OAuth login.

Deployment to Heroku

Once you have ASIDE running locally, getting it deployed to Heroku is simple. First, tell Heroku which stack you want this app to use.

heroku stack:set heroku-18

Next install Bundler and ASIDE's dependencies.

gem install bundler
bundle install

Finally, push the code to Heroku.

git commit -a -m "deploying aside"
git push heroku master

Now you should be able to access your instance of ASIDE hosted on Heroku! Unfortunately the login buttons still won't work because you havent configured OAuth. To do that, follow the steps in the next section.

Configuring OAuth

Before you can login from your new Heroku app, you will need to make some configuration changes within Salesforce and Heroku. ASIDE's login works based on Salesforce's OAuth web server flow (more info available here), as such you will need to create a Connected App within a Salesforce organization for it to work. Create the Connected App with the following details:

After saving the Connected App, there will be two values available on the detail page: Consumer Key and Consumer Secret. These values need to be set in the configuration of your Heroku application. From the application dashboard in Heroku, choose your application and click the Settings tab. Scroll down and click to Reveal Config Vars. Add the following config vars:

  • Key: CID; Value: < Salesforce Connected App Consumer Key >
  • Key: SEC; Value: < Salesforce Connected App Consumer Secret >
  • Key: URL; Value: < URL of your Heroku application. E.g. >

Save these values and wait 10 minutes, then you should be able to login to your instance of ASIDE! If you can't login double check your configuration or see the help
