Deno Deploy Drash Test

Usage

Running the app

# Set DRASH_COMPILE_TEMPLATES to true so that the templates are precompiled
# If you run this with --watch, then you will run an infinite loop because the
# compilation of templates will cause the directory to change and case --watch
# to fire over and over
export DRASH_COMPILE_TEMPLATES=true && deno run -A app.ts

Compiling templates

In app.ts, there is a tengine.compileTemplates() call. This call takes in an array of templates that it should compile and store in the ./views directory as {template}.renderer.js. For example, if the template you provide is index.html, then it will create an index.renderer.js file. Template are relative to the views_path you use when instantiating TengineService.

This dev flow is super wack and can def be improved, but... when adding a new template to be compiled, do the following:

Create your template (if not created already).
Add your template to the tengine.compileTemplates().
Run export DRASH_COMPILE_TEMPLATES=true && deno run -A app.ts. This will create a .renderer.js file (e.g., if you provide my_cool_page.html, then the renderer file will be my_cool_page.renderer.js).
Go to jae_write_file.ts and add an import statement to your .renderer.js file that was just created. For example:
```
import { buildTemplate as buildMyCoolPage } from "../../views/my_cool_page.renderer.js";
```
Scroll down until you find switch (jsPath) { ... }.

Add the renderer to the list of cases. For example:

switch (jsPath) {
  case "./views/index.renderer.js":
    return buildIndex(data);
  case "./views/my_cool_page.renderer.js": // Set the case ...
    return buildMyCoolPage(data); // ... and call the renderer
  default:
    break;
}

Restart your server.

Trials

Tengine

Using Worker to render templates during runtime. Doesn't work because "Worker is not enabled in this context" error in Deploy.
Compiling templates during runtime using Deno.writeFile(), caching them, and calling them when needed. Didn't work because "Deno.writeFile is not enabled in this context" error.
Precompiled the templates before starting the server and stored the templates as .js files that could be imported during runtime. Didn't work because "Dynamic import is not enabled in this context" error.

Everything leads me to believe that you need to have as much static data as possible OR create a single page app.
