How do I write an async request to get a markdown file's content? Svelte - json

Question

I'm having a great time building my blog with Svelte, but I'm switching the structure to to be accessed through a JSON API.
Right now it's easy to get the markdown metadata and path, but I'd love to also get the content.
How would I modify this posts.json.js file to also get the content?
const allPostFiles = import.meta.glob('../blog/posts/*.md')
const iterablePostFiles = Object.entries(allPostFiles)
const allPosts = await Promise.all(
iterablePostFiles.map(async ([path, resolver]) => {
const { metadata } = await resolver()
const postPath = path.slice(2, -3)
return {
meta: metadata,
path: postPath
}
})
)
const sortedPosts = allPosts.sort((a, b) => {
return new Date(b.meta.date) - new Date(a.meta.date)
})
return {
body: sortedPosts
}

Answer 1

Install and enable the vite-plugin-markdown
// svelte.config.js
import { plugin as markdown, Mode } from "vite-plugin-markdown";
/** #type {import('#sveltejs/kit').Config} */
export default {
kit: {
vite: {
plugins: [markdown({ mode: Mode.HTML })],
},
},
};
then the content will be available as html and frontmatter data as attributes
iterablePostFiles.map(async ([path, resolver]) => {
const { attributes, html } = await resolver();
return {
attributes,
html,
path: path.slice(2, -3),
};
})
(I suggest adding the metadata into the markdown files via frontmatter )

The answer above works perfectly, but it also works to tweak the API with this code:
const allPosts = await Promise.all(
iterablePostFiles.map(async ([path, resolver]) => {
const { metadata } = await resolver()
// because we know every path will start with '..' and end with '.md', we can slice from the beginning and the end
const postPath = path.slice(2, -3)
const post = await resolver()
const content = post.default.render()
return {
meta: metadata,
path: postPath,
text: content
}
})
)
The important addition is this:
const post = await resolver()
const content = post.default.render()
using these variable chains to avoid using the JS reserved word default.
