 1 | # stytch-go-magic-links
 2 | 
 3 | This is a lightweight [Stytch](https://stytch.com) + [Go](https://go.dev/) example app which demonstrates a quick Stytch implementation using our [Email Magic Links](https://stytch.com/docs/guides/magic-links/email-magic-links/api) and [Sessions](https://stytch.com/docs/guides/sessions/using-sessions) products.
 4 | 
 5 | <p align="center"><img src="./public/example-app-image.png" alt="stytch" width="50%"/></p>
 6 | 
 7 | # Running locally
 8 | 
 9 | ## Set up
10 | 
11 | ### In the Stytch Dashboard
12 | 
13 | 1. Create a [Stytch](https://stytch.com/) account. Once your account is set up a Project called "My first project" will be automatically created for you.
14 | 
15 | 2. Navigate to [Redirect URLs](https://stytch.com/dashboard/redirect-urls), and add `http://localhost:3000/authenticate` as the types **Login** and **Sign-up**.
16 | 
17 | 3. Finally, navigate to [API Keys](https://stytch.com/dashboard/api-keys), and copy your `project_id` and `secret`. You will need these value later on.
18 | 
19 | ### On your machine
20 | 
21 | In your terminal, clone the project and install dependencies:
22 | 
23 | ```bash
24 | git clone https://github.com/stytchauth/stytch-go-magic-links.git
25 | cd stytch-go-magic-links
26 | go get
27 | ```
28 | 
29 | Next, create a `.env.local` file by running the command below and replacing the keys with those copied from step 3 above.
30 | 
31 | ```bash
32 | cp .env.template .env.local
33 | # Replace your keys in new .env.local file with the API keys from step 3 above
34 | ```
35 | 
36 | ## Running locally
37 | 
38 | After completing all the set up steps above the application can be run with the command:
39 | 
40 | ```go run main.go```
41 | 
42 | The application will be available at [`http://localhost:3000`](http://localhost:3000) and you'll be able to login with Email Magic Links! 
43 | 
44 | To do so, enter your email, then check for the Stytch email and click the sign in button.
45 | 
46 | You should be signed in!
47 | 
48 | ## Next steps
49 | 
50 | This example app showcases a small portion of what you can accomplish with Stytch. Here are a few ideas to explore:
51 | 
52 | 1. Add additional login methods like [Passwords](https://stytch.com/docs/guides/passwords/api) or [Passcodes](https://stytch.com/docs/guides/passcodes/api).
53 | 2. Secure your app further by building MFA authentication using methods like [WebAuthn](https://stytch.com/docs/guides/webauthn/api).
54 | 
55 | 
56 | ## Get help and join the community
