Installing prerequisites

Ruby

  1. If you don't already have a Ruby version manager, we highly recommend rbenv. Please follow their installation guide.
  2. With the Ruby version manager, install the Ruby version listed on our badge. (ie with rbenv: rbenv install 2.6.1)

Yarn

Please refer to their installation guide.

PostgreSQL

Dev.to requires PostgreSQL version 9.4 or higher. The easiest way to get started is to use Postgres.app. Alternatively, check out the official PostgreSQL site for more granular version.

Installing Dev.to

  1. Fork dev.to repository, ie. https://github.com/thepracticaldev/dev.to/fork
  2. Clone your forked repository, ie. git clone https://github.com/<your-username>/dev.to.git
  3. Install bundler with gem install bundler
  4. Set up your environment variables/secrets

    • Take a look at Envfile. This file lists all the ENV variables we use and provides a fake default for any missing keys. You'll need to get your own free Algolia credentials to get your development environment running.
    • This guide will show you how to get free API keys for additional services that may be required to run certain parts of the app.
    • For any key that you wish to enter/replace:
  5. Create config/application.yml by copying from the provided template (ie. with bash: cp config/sample_application.yml config/application.yml). This is a personal file that is ignored in git.
  6. Obtain the development variable and apply the key you wish to enter/replace. ie:

    GITHUB_KEY: "SOME_REAL_SECURE_KEY_HERE"
    GITHUB_SECRET: "ANOTHER_REAL_SECURE_KEY_HERE"
    • If you are missing ENV variables on bootup, envied gem will alert you with messages similar to 'error_on_missing_variables!': The following environment variables should be set: A_MISSING_KEY..
    • You do not need "real" keys for basic development. Some features require certain keys, so you may be able to add them as you go.
  7. Run bin/setup

    Sorry, you can't use byebug without Readline. To solve this, you need to
    rebuild Ruby with Readline support. If using Ubuntu, try `sudo apt-get
    install libreadline-dev` and then reinstall your Ruby.

LoadError: dlopen(/Users/nickytonline/.rbenv/versions/2.6.1/lib/ruby/2.6.0/x86_64-darwin18/readline.bundle, 9): Library not loaded: /usr/local/opt/readline/lib/libreadline.<some version number>.dylib

Solution: Run ln -s /usr/local/opt/readline/lib/libreadline.dylib /usr/local/opt/readline/lib/libreadline.<some version number>.dylib from the command line then run bin/setup again. You may have a different version or libreadline, so replace <some version number> with the version that errored.

If you encountered any errors that you subsequently resolved, please consider updating this section with your errors and their solutions.
