# Deploy FastAPI on Deta
|
||||
|
||||
In this section you will learn how to easily deploy a **FastAPI** application on <a href="https://www.deta.sh/?ref=fastapi" class="external-link" target="_blank">Deta</a> using the free plan. 🎁
|
||||
|
||||
It will take you about **10 minutes**.
|
||||
|
||||
!!! info
|
||||
<a href="https://www.deta.sh/?ref=fastapi" class="external-link" target="_blank">Deta</a> is a **FastAPI** sponsor. 🎉
|
||||
|
||||
## A basic **FastAPI** app
|
||||
|
||||
* Create a directory for your app, for example `./fastapideta/` and enter in it.
|
||||
|
||||
### FastAPI code
|
||||
|
||||
* Create a `main.py` file with:
|
||||
|
||||
```Python
|
||||
from fastapi import FastAPI
|
||||
|
||||
app = FastAPI()
|
||||
|
||||
|
||||
@app.get("/")
|
||||
def read_root():
|
||||
return {"Hello": "World"}
|
||||
|
||||
|
||||
@app.get("/items/{item_id}")
|
||||
def read_item(item_id: int):
|
||||
return {"item_id": item_id}
|
||||
```
|
||||
|
||||
### Requirements
|
||||
|
||||
Now, in the same directory create a file `requirements.txt` with:
|
||||
|
||||
```text
|
||||
fastapi
|
||||
```
|
||||
|
||||
!!! tip
|
||||
You don't need to install Uvicorn to deploy on Deta, although you would probably want to install it locally to test your app.
|
||||
|
||||
### Directory structure
|
||||
|
||||
You will now have one directory `./fastapideta/` with two files:
|
||||
|
||||
```
|
||||
.
|
||||
└── main.py
|
||||
└── requirements.txt
|
||||
```
|
||||
|
||||
## Create a free Deta account
|
||||
|
||||
Now create a <a href="https://www.deta.sh/?ref=fastapi" class="external-link" target="_blank">free account on Deta</a>, you just need an email and password.
|
||||
|
||||
You don't even need a credit card.
|
||||
|
||||
## Install the CLI
|
||||
|
||||
Once you have your account, install the Deta <abbr title="Command Line Interface application">CLI</abbr>:
|
||||
|
||||
=== "Linux, macOS"
|
||||
|
||||
<div class="termy">
|
||||
|
||||
```console
|
||||
$ curl -fsSL https://get.deta.dev/cli.sh | sh
|
||||
```
|
||||
|
||||
</div>
|
||||
|
||||
=== "Windows PowerShell"
|
||||
|
||||
<div class="termy">
|
||||
|
||||
```console
|
||||
$ iwr https://get.deta.dev/cli.ps1 -useb | iex
|
||||
```
|
||||
|
||||
</div>
|
||||
|
||||
After installing it, open a new terminal so that the installed CLI is detected.
|
||||
|
||||
In a new terminal, confirm that it was correctly installed with:
|
||||
|
||||
<div class="termy">
|
||||
|
||||
```console
|
||||
$ deta --help
|
||||
|
||||
Deta command line interface for managing deta micros.
|
||||
Complete documentation available at https://docs.deta.sh
|
||||
|
||||
Usage:
|
||||
deta [flags]
|
||||
deta [command]
|
||||
|
||||
Available Commands:
|
||||
auth Change auth settings for a deta micro
|
||||
|
||||
...
|
||||
```
|
||||
|
||||
</div>
|
||||
|
||||
!!! tip
|
||||
If you have problems installing the CLI, check the <a href="https://docs.deta.sh/docs/micros/getting_started?ref=fastapi" class="external-link" target="_blank">official Deta docs</a>.
|
||||
|
||||
## Login with the CLI
|
||||
|
||||
Now login to Deta from the CLI with:
|
||||
|
||||
<div class="termy">
|
||||
|
||||
```console
|
||||
$ deta login
|
||||
|
||||
Please, log in from the web page. Waiting..
|
||||
Logged in successfully.
|
||||
```
|
||||
|
||||
</div>
|
||||
|
||||
This will open a web browser and authenticate automatically.
|
||||
|
||||
## Deploy with Deta
|
||||
|
||||
Next, deploy your application with the Deta CLI:
|
||||
|
||||
<div class="termy">
|
||||
|
||||
```console
|
||||
$ deta new
|
||||
|
||||
Successfully created a new micro
|
||||
|
||||
// Notice the "endpoint" 🔍
|
||||
|
||||
{
|
||||
"name": "fastapideta",
|
||||
"runtime": "python3.7",
|
||||
"endpoint": "https://qltnci.deta.dev",
|
||||
"visor": "enabled",
|
||||
"http_auth": "enabled"
|
||||
}
|
||||
|
||||
Adding dependencies...
|
||||
|
||||
|
||||
---> 100%
|
||||
|
||||
|
||||
Successfully installed fastapi-0.61.1 pydantic-1.7.2 starlette-0.13.6
|
||||
```
|
||||
|
||||
</div>
|
||||
|
||||
You will see a JSON message similar to:
|
||||
|
||||
```JSON hl_lines="4"
|
||||
{
|
||||
"name": "fastapideta",
|
||||
"runtime": "python3.7",
|
||||
"endpoint": "https://qltnci.deta.dev",
|
||||
"visor": "enabled",
|
||||
"http_auth": "enabled"
|
||||
}
|
||||
```
|
||||
|
||||
!!! tip
|
||||
Your deployment will have a different `"endpoint"` URL.
|
||||
|
||||
## Check it
|
||||
|
||||
Now open your browser in your `endpoint` URL. In the example above it was `https://qltnci.deta.dev`, but yours will be different.
|
||||
|
||||
You will see the JSON response from your FastAPI app:
|
||||
|
||||
```JSON
|
||||
{
|
||||
"Hello": "World"
|
||||
}
|
||||
```
|
||||
|
||||
And now go to the `/docs` for your API, in the example above it would be `https://qltnci.deta.dev/docs`.
|
||||
|
||||
It will show your docs like:
|
||||
|
||||
<img src="/img/deployment/deta/image01.png">
|
||||
|
||||
## Enable public access
|
||||
|
||||
By default, Deta will handle authentication using cookies for your account.
|
||||
|
||||
But once you are ready, you can make it public with:
|
||||
|
||||
<div class="termy">
|
||||
|
||||
```console
|
||||
$ deta auth disable
|
||||
|
||||
Successfully disabled http auth
|
||||
```
|
||||
|
||||
</div>
|
||||
|
||||
Now you can share that URL with anyone and they will be able to access your API. 🚀
|
||||
|
||||
## HTTPS
|
||||
|
||||
Congrats! You deployed your FastAPI app to Deta! 🎉 🍰
|
||||
|
||||
Also notice that Deta correctly handles HTTPS for you, so you don't have to take care of that and can be sure that your clients will have a secure encrypted connection. ✅ 🔒
|
||||
|
||||
## Check the Visor
|
||||
|
||||
From your docs UI (they will be in a URL like `https://qltnci.deta.dev/docs`) send a request to your *path operation* `/items/{item_id}`.
|
||||
|
||||
For example with ID `5`.
|
||||
|
||||
Now go to <a href="https://web.deta.sh/" class="external-link" target="_blank">https://web.deta.sh</a>.
|
||||
|
||||
You will see there's a section to the left called <abbr title="it comes from Micro(server)">"Micros"</abbr> with each of your apps.
|
||||
|
||||
You will see a tab with "Details", and also a tab "Visor", go to the tab "Visor".
|
||||
|
||||
In there you can inspect the recent requests sent to your app.
|
||||
|
||||
You can also edit them and re-play them.

## Learn more
|
||||
|
||||
At some point you will probably want to store some data for your app in a way that persists through time. For that you can use <a href="https://docs.deta.sh/docs/base/py_tutorial?ref=fastapi" class="external-link" target="_blank">Deta Base</a>, it also has a generous **free tier**.
|
||||
|
||||
