This document explains the changes made to fix the template rendering issues in the DEV Partner Portal application.
The template system was experiencing issues with nested conditionals and complex template syntax. This resulted in template code being rendered directly in the HTML output instead of being processed correctly.
Examples of issues:
- Template variables like
{{value}}appearing in the rendered output - Conditional statements like
{{#if type == "select"}}showing up in the HTML - Nested conditionals not being processed correctly
We took a two-pronged approach to fix these issues:
- Simplified Components: Created simplified versions of all components that avoid complex template syntax
- Direct HTML: Used direct HTML instead of complex conditional logic in templates
We created the following simplified components:
/views/components/forms/simple-submission-form.html/views/components/forms/simple-magic-link-form.html/views/components/forms/simple-company-info-form.html/views/components/ui/simple-success-message.html/views/components/ui/simple-error-message.html/views/components/ui/simple-account-info.html/views/components/uploadcare/simple-image-gallery.html/views/components/ad-creation/simple-ad-preview.html
These components use direct HTML instead of complex template syntax, making them more reliable and easier to maintain.
We also created simplified versions of the main templates:
/views/templates/simple-landing-template.html/views/templates/simple-continue-template.html
These templates use the simplified components and avoid complex template syntax.
We updated the controllers to use the simplified templates:
// Updated renderLandingPage function
export async function renderLandingPage(c: Context): Promise<Response> {
const html = await renderTemplate("/views/templates/simple-landing-template.html", {}, import.meta.url);
return c.html(html);
}
// Updated renderContinuationPage function
export async function renderContinuationPage(c: Context): Promise<Response> {
// ...
const html = await renderTemplate("/views/templates/simple-continue-template.html", {
COMPANY_NAME: submission.companyName,
EMAIL: submission.email,
ID: id,
HOST: host
}, import.meta.url);
return c.html(html);
}
- Reliability: Simplified templates are less prone to rendering errors
- Maintainability: Direct HTML is easier to understand and maintain
- Performance: Simpler templates are faster to render
- Debugging: Issues are easier to identify and fix
For a more robust solution in the future, we could:
- Implement a more sophisticated template engine like Handlebars or EJS
- Create a custom component system with proper escaping and processing
- Add template validation to catch syntax errors before rendering
- Implement server-side rendering for complex components
However, the current simplified approach should be sufficient for the needs of the DEV Partner Portal application while being much more reliable than the previous implementation.
