Package users implements common web user workflows. Most of the provided functions are regular net/http handler functions. The following functionality is provided: Special emphasis is placed on reducing the risk of someone hijacking user accounts. This is achieved by enforcing a certain user structure and following certain procedures: If your application does not follow these principles, you may not be able to use this package as is. However, the code may serve as a starting point if you apply its principles to your own use case. Note also the following: The users.Main() function registers all handlers and starts an HTTP server: Any other handlers can be added to the http.DefaultServeMux before calling users.Main(). Alternatively, you can start your own HTTP server. See the implementation of users.Main() for how to add the package's handlers. See the package example for a most basic way to use the package. In addition, the global Config struct contains all the variables that need to be adjusted for your specific application. It provides sensible defaults out of the box which you can see in its documentation. The fields are as follows: The following fields control how templates are handled: If your application supports internationalization, you can set the Internationalization field to true. If set to true, this package's code checks for the "lang" cookie and appends its value to the HTMLTemplateDir and MailTemplateDir directories to search for template files. Cookie values must be of the format "xx" or "xx-XX" (e.g. "en-US"). If they don't have this format or if the corresponding subdirectory does not exist, the search falls back to the HTMLTemplateDir and MailTemplateDir directories. It is up to the application to set the "lang" cookie. Emails are sent if the SendEmails field is set to true. You can provide your own email function by implementing the SendEmail field. Alternatively, the net/smtp package is used to send emails. The following fields need to specified (fields starting with "SMTP" are only needed when you don't provide your own SendEmail implementation): A number of functions serve as the interface to your database: Anyone using this package must define a type which implements this package's User interface. A user is in one of three possible states: Users have an ID which must be unique (e.g. generated by CUID() in the package github.com/rivo/sessions). But this package may access users based on their unique email address, their verification ID, or their password reset token. You must implement the Config.NewUser function. There are basic HTML templates (in the "html" subdirectory) and email templates (in the "mail" subdirectory). All HTML templates starting with "error_" are templates that will generate error messages which are then embedded in another HTML template. When starting to work with this package, you will want to make a copy of these two subdirectories and modify the templates to your needs. This package implements some functions to render templates which are also public so you may use them in other places, too. The function RenderPage() takes a template filename and a data object (to which the template will be bound), renders the template, and sends it to the browser. Instead of calling this function, however, RenderPageBasic() is used more often. It calls RenderPage() but populates the data object with the Config object and the User object (if one was provided). If an error message needs to be shown to the user, RenderPageError() can be used. This actually involves two templates, one to generate only the error message (these template files start with "error_"), and the other to generate the HTML file which shows the error message. Config and User will also be bound to the latter as well as any data sent to the error message template. There is another function for errors, RenderProgramError(), which is used to show program errors. These are unexpected errors, for example database connection issues, and should always be followed up on. While the user usually only sees a basic error message, more detailed information about the error is sent to the logger for further inspection. The SendMail() function renders mail templates (based on text/template) to send them to the user's email address. When writing your own templates, it is helpful to make a copy of the existing example templates and modify them to your needs. All templates include a header and a footer file. If you include more files, you will need to set the Config.HTMLTemplateIncludes and Config.MailTemplateIncludes fields accordingly.
