Using Strapi CMS with Neon Postgres and Astro to build a blog

A step-by-step guide for building your own blog in an Astro application with Strapi CMS and Postgres powered by Neon

In this guide, you will learn how to set up a serverless Postgres database with Neon, configure Strapi CMS with Postgres, define a blog schema, and author content using Strapi CMS. The guide also covers configuring API read permissions and building a dynamic frontend with Astro to display blog pages based on Strapi content.


To follow the steps in this guide, you will need the following:


Provisioning a serverless Postgres database powered by Neon

Using a serverless Postgres database powered by Neon lets you scale compute resources down to zero, which helps you save on compute costs.

To get started, go to the Neon console and create a project.

You will then be presented with a dialog that provides a connection string of your database. Click on Pooled connection option and the connection string automatically updates to a pooled connection string.

Neon Connection Details

All Neon connection strings have the following format:

  • <user> is the database user.
  • <password> is the database user’s password.
  • <endpoint_hostname> is the host with as the top-level domain (TLD).
  • <port> is the Neon port number. The default port number is 5432.
  • <dbname> is the name of the database. neondb is the default database created with each Neon project if you do not define your own.
  • ?sslmode=require is an optional query parameter that enforces SSL mode for better security when connecting to the Postgres instance.

Each of the above values (except sslmode) is used in the next step — creating a local instance of the Strapi CMS application with Postgres.

Setting up Strapi locally with Postgres

Let's begin with creating a Strapi CMS backend to serve the content for blog posts. Open your terminal and run the following command:

npx create-strapi-app@latest blog-api

npx create-strapi-app is the recommended way to scaffold a Strapi CMS project quickly.

When prompted, choose the following:

Create Strapi CMS project

  • Custom (manual) settings as the installation type.
  • TypeScript as the preferred language.
  • postgres as the default database client.
  • neondb as the database name.
  • <endpoint_hostname> as the host.
  • 5432 as the port.
  • neondb_owner as the username.
  • <password> as the password.
  • y to enable an SSL connection.

Once that’s done, change to the project directory and start the app:

cd blog-api
yarn develop

The command strapi develop runs, which takes care of creating the minimal schema required by Strapi CMS in the Neon Postgres database. When the setup is complete, you will be taken to http://localhost:1337/admin automatically. You will need to create an account for your locally hosted Strapi CMS instance. Strapi CMS makes sure to store the credentials (and all other data) in your Neon Postgres database.

To proceed, click the Let's start button to access the admin dashboard. Now, let's learn how to create the blog schema in Strapi CMS.

Configure a blog schema in Strapi CMS

Once you have logged into the admin dashboard, it will by default, take you to the Content-Type Builder section. Here's where you can start to create the Blog schema. Click on + Create new collection type to get started.

Content-Type Builder

Enter the Display name for your blog schema. For example, name it Blog, and click Continue.

Create a collection type

The application now asks you to create the first field inside the schema. Let's start with the Title of the blog first. Select Text, and it will automatically take you to the field detail section.

Select a field

Enter Title as the Name of the first field and click Finish.

Add new title field

Once that's done, you are taken to an overview of the newly created Blog schema. Let's add two more fields. Click on + Add another field to this collection type.

Add another field

First, you will add an image to be associated with the blog. Select Media and you are automatically taken to the asset detail section.

Add media

Enter Image as the Name of the image field and click Finish.

Add image field

Next, you will add a markdown to be associated with the blog. Select Rich Text (Markdown). You are automatically taken to the field detail section.

Add Markdown field

Enter text as the Name of the markdown field and click Finish.

Enter markdown field name

Great! Click Save to save the present configuration.

Configuration saved

Click on the Content Manager button in the sidebar to start adding your first blog content. Click + Create new entry to get started.

Content Manager

Enter the Title, select the Image, and input the markdown associated with the blog. You are now done writing your first post in the local Strapi CMS instance. All the data is synchronized in Postgres (powered by Neon). To finish off the content creation process, click Save and Publish.

Create an entry

With that done, let's move on to configuring read permissions for connected clients to access the data corresponding to the blog schema via an API.

Configure API Read Permissions in Strapi CMS

To be able to fetch the data authored in your local Strapi CMS instance, you will need to configure what is readable and writeable using APIs. Navigate to Settings > API Tokens in your admin dashboard. Click on Create new API Token to start creating a new API token.

API tokens

Enter a Name to be associated with the token and set Token Duration to unlimited for the sake of this example. Finally, click Save to obtain the API token.

Create API token

Copy the API token and store it somewhere safe as STRAPI_API_TOKEN.

Now, let's move on to creating an Astro application to create dynamic blog pages based on blog data that's accessible via your locally hosted instance of Strapi CMS.

Create a new Astro application

Let’s get started by creating a new Astro project. Open your terminal and run the following command:

npm create astro@latest blog-ui

npm create astro is the recommended way to scaffold an Astro project quickly.

When prompted, choose:

  • Empty when prompted on how to start the new project.
  • Yes when prompted if plan to write Typescript.
  • Strict when prompted how strict Typescript should be.
  • Yes when prompted to install dependencies.
  • Yes when prompted to initialize a git repository.

Once that’s done, change to the project directory and start the app:

cd blog-ui
npm run dev

The app should be running on localhost:4321. Let's close the development server for now.

Next, execute the following command to install the necessary libraries and packages for building the application:

npm install dotenv marked @tailwindcss/typography
npm install -D @types/node

The commands above install the packages, with the -D flag specifying the libraries intended for development purposes only.

The libraries installed include:

  • dotenv: A library for handling environment variables.
  • marked: A markdown parser and compiler.
  • @tailwindcss/typography: A set of prose classes for HTML rendered from Markdown or pulled from a CMS.

The development-specific libraries include:

Then, add the following lines to your tsconfig.json file to make relative imports within the project easier:

  "extends": "astro/tsconfigs/strict",
  "compilerOptions": {
    "baseUrl": ".",
    "paths": {
      "@/*": ["src/*"]

Now, create a .env file. You are going to add the API token obtained earlier.

The .env file should contain the following keys:

# .env


Integrate Tailwind CSS in your Astro application

For styling the app, you will use Tailwind CSS. Install and set up Tailwind at the root of your project's directory by running:

npx astro add tailwind

When prompted, choose:

  • Yes when prompted to install the Tailwind dependencies.
  • Yes when prompted to generate a minimal tailwind.config.mjs file.
  • Yes when prompted to make changes to the Astro configuration file.

The command finishes integrating TailwindCSS into your Astro project and installs the following dependencies:

  • tailwindcss: TailwindCSS as a package to scan your project files to generate corresponding styles.
  • @astrojs/tailwind: The adapter that brings Tailwind's utility CSS classes to every .astro file and framework component in your project.

To load pre-configured styles for your HTML (rendered from markdown), update your tailwind.config.mjs as follows:

/** @type {import('tailwindcss').Config} */
export default {
  content: ['./src/**/*.{astro,html,js,jsx,md,mdx,svelte,ts,tsx,vue}'],
  theme: {
    extend: {},
  plugins: [require('@tailwindcss/typography')],

Create dynamic blog routes in Astro

To programmatically create pages as you keep authoring more content in your locally hosted Strapi CMS, you are going to use dynamic routes in Astro. With dynamic routes, you create a single file with a name like [slug].astro, where slug represents a unique and dynamic variable for each blog. Using getStaticPaths, you can programmatically create multiple blog pages with custom data using Strapi CMS as your data source. Let's see this in action. Create a file named [slug].astro in the src/pages directory with the following code:

// File: src/pages/[slug].astro

import "dotenv/config";
import { marked } from 'marked';

export async function getStaticPaths() {
  const response = await fetch(``, {
    headers: {
      "Content-Type": "application/json",
      Authorization: `Bearer ${process.env.STRAPI_API_TOKEN}`,
  const {data} = await response.json();
  return{ id, attributes }) => ({
    params: { slug: id },
    props: attributes,

const { Title, text, Image } = Astro.props

const markdown = marked.parse(text)

<html lang="en">
    <meta charset="utf-8" />
    <link rel="icon" type="image/svg+xml" href="/favicon.svg" />
    <meta name="viewport" content="width=device-width" />
    <meta name="generator" content={Astro.generator} />
    <img src={`${[0].attributes.url}`} />
    <article set:html={markdown} />

Let's understand the code above in two parts:

  • Inside getStaticPaths function, a fetch call is made to the locally hosted Strapi CMS API to get all the blogs with their Title, Image and text values. Looping over each blog item, an array is created that passes all the data obtained as the props, and its id as the unique variable to be associated with each blog.

  • The HTML section represents the content of a particular blog page. The blog data attributes such as Title, Image URL, and markdown are obtained from Astro.props (passed in getStaticPaths as props). Further, the markdown is parsed into HTML using the marked library, and injected into the DOM using set:html template directive of Astro.

Build and Test your Astro application locally

To test the Astro application in action, prepare a build and run the preview server using the following command:

npm run build && npm run preview

Scale-to-zero with Postgres (powered by Neon)

Interestingly, during the entire process of building this application, you have used Neon's Scale-to-zero feature which places your Postgres compute endpoint into an Idle state after 5 minutes of inactivity. Click the Operations button in your Neon console sidebar to see when the compute was started and automatically suspended to reduce compute usage.
