Encoding and decoding also adds a computational overhead for both the server and the client. Therefore, base64 is suitable for sending images and small files under MB.
Multipart forms, on the other hand, are more "unnatural" to the APIs, since the data is encoded in a different format and requires a different way of handling. However, the increased performance with larger files and the ability to stream files makes multipart form data more desirable for uploading larger files, such as videos.
First, let's set up a Rails 5 API application and scaffold a model that is going to be used. Move to the directory of the new project: 1 cd fileuploadapp Go to the Gemfile and uncomment jbuilder and rack-cors. Simply put, rack-cors will enable browser-based applications AngularJS, React and mobile applications to request information from the API.
This is not a problem for this guide, since we are going to work only with a local server. Install the gems: 1 bundle install bash With the gems installed, the model is going to be scaffolded with Jbuilder-generated views and be ready to be consumed by client-side applications. Note that there is still no information about the file - file information will be included in the model's schema at a later stage.
UPDATE: You may have heard about Lit, our i18n gem for Rails apps translations...
For now, we are all set to go ahead and migrate the model into the database: 1 rails db:migrate bash This will create a table in the database for the new model. Note that in Rails 5 you can use rails instead of rake for executing a migration command.We found out this alleviates most of the user pain and is a better alternative than simply waiting.
