You need to install.
FastAPI
pip install fastapiASGI Server
pip install "uvicorn[standard]"Templating Engine
For this example we will be using Jinja2.
pip install Jinja2Create a "templates" folder in your project
You need to create a new "templates" folder and create a "base.html" file inside.
mkdir templates && touch templates/base.htmlnow we will add some basic html.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Document</title>
</head>
<body></body>
</html>Add the TemplateResponse to your route response
Now we need setup Jinja2Templates with our "templates" folder and return a TemplateResponse in our index route.
from fastapi import FastAPI, Request
from fastapi.templating import Jinja2Templates
app = FastAPI()
templates = Jinja2Templates(directory="templates")
@app.get("/")
async def index(request: Request):
return templates.TemplateResponse("base.html", {"request": request})Here we will be adding the TailwindCSS files.
mkdir tailwindcssStart a new terminal inside your project folder and change the working directory to the "tailwindcss" folder.
cd tailwindcssand then run the following command, with the package manager you'd like to use.
npm install -D tailwindcss @tailwindcss/cli pnpm install -D tailwindcss @tailwindcss/cli yarn add -D tailwindcss @tailwindcss/cliHere we will be adding our custom styles.
For that we need to create a new "styles" folder inside our "tailwindcss" folder.
mkdir stylesnow we need to create a new file "app.css" inside this folder.
touch styles/app.cssthen add the following directives.
@import "tailwindcss";
@source "../../templates";This proccess will generate a "app.css" file inside a new "static/css" folder.
The "--watch" flag will make sure that the styles are updated every time you make a change in your files.
npx @tailwindcss/cli -i ./styles/app.css -o ../static/css/app.css --watchMount the static folder
In order to mount this folder we need to add the following lines to our main.py file.
Import the static files.
from fastapi.staticfiles import StaticFilesAdd the static folder to your app.
app.mount("/static", StaticFiles(directory="static"), name="static")Now we can add the stylesheet to our base.html file.
<link href="{{url_for('static',path='/css/app.css')}}" rel="stylesheet" />In order to serve compressed files we need to import the middleware.
add the middleware to your app.
app.add_middleware(GZipMiddleware)We can create a script in the package.json file to run the TailwindCSS CLI build process.
"scripts": {
"dev": "npx @tailwindcss/cli -i ./styles/app.css -o ../static/css/app.css --watch"
},And then simply run.
npm run devpnpm devyarn devto run the Tailwind CSS build process.
Now you have Tailwind CSS v4.0 set up in your FastAPI project.
