Structure Your ERb and Partials for more Maintainable Front-end Code in Rails

When should we use a partial or a helper–or a partial rendered using a helper? Which elements should be extracted into partials or helpers? When can we use a simple helper and skip the partial file? When should we use the built-in tag helpers instead of writing HTML directly?These are all nuanced questions without objective right or wrong answers. So we’ll explore options in the context of a real example and take a holistic approach to translating static markup into a partial and the relevant helper methods. We’ll dig into the trade-offs and alternatives that inform and explain the decision-making.
