<p>hey everyone! first time poster in this subreddit. I&#39;ve been working with go for about 4 months now and absolutely love it.</p> <p>Anyways, I&#39;m working on a relatively complex web application back-end and have gotten a little concerned that in places where I need to return errors, I am using string literals for the string value which I&#39;m starting to think could be a major headache later:</p> <pre><code>if roles.IsAdmin(&amp;user) != true { return fmt.Errorf(&#34;UNAUTHORIZED&#34;) } </code></pre> <p>So I&#39;m wondering: would it be bad practice to define in my application an <code>errors</code> module and define every application error string in there? E.g:</p> <pre><code>import &#34;github.com/me/myproject/errors&#34; if roles.IsAdmin(&amp;user) != true { return fmt.Errorf(errors.ErrUnauthorized) } </code></pre> <p>Or is the correct approach to have the errors defined in the module of which they could be produced, e.g:</p> <pre><code>if roles.IsAdmin(&amp;user) != true { return fmt.Errorf(roles.ErrUnauthorized) } </code></pre>
