This Xano backend provides authentication (without the Firebase setup) and allows you to upload images and comments. The authentication works by having a login form that returns an auth-token that Bravo propagates to other requests.

We have to change the stock functionality to make it work with the image upload in Bravo.

A) Setup Xano

1.Signup with Xano

2.At how do you want to start — choose “Photo sharing social media platform”

B) Edit photo API to work with Bravo Image upload

1.Click on API on the left hand side

2.In photo sharing click on View 27 Endpoints to get this (record the Base Request URL highlighted in red below, you will need it later in the Bravo API Binding steps):

3.click on the /photo endpoint

In inputs click on image

In right sidebar click on the toggle to make it hidden from the API
Click on SAVE

5.Click on + next to inputs

Click on Text to add text field

Name the text field ‘image_url’

Set required to ‘Yes’
Click SAVE

6.Click on + next to function stack

Click on content upload

Click on create image metadata

Highlight the create image from file block and use the 4 arrows icon on the block to reorganize the blocks so this one is above the add recordblock.
In create image from file block change value to ‘image_url’ in the drop down list
Click SAVE

7.Click on Add record from photo block

Set image to Var_1 from the dropdown the output from the create image block

The photo API should now look like this:

Now we need to get an auth-token to help do the setup in Bravo.

8.Click the blue Run & Debug button (above). This will open the debug pane:

If you click on the cog in blue, it will bring up a list of users, just click on one and Xano will log that user in and give you an auth-token (starting ‘eyJ…’), You need to copy and paste this auth-token somewhere as we will need it in the Bravo API step.

C) Setup the Design in Bravo

Signup for Bravo
Click on Import Figma File
Import this figma file — https://www.figma.com/file/OjR388TcU5ESIhngTEILVP/Foodgram-with-Xano?node-id=0%3A1

Your design should look like this in Bravo:

D) Setup the APIs in Bravo

We need to add all the api requests that we need from Xano in Bravo:

1.Click on Data Library in Bravo on the left hand side

2.Click on New Collection

3.Click on ‘Custom API’ and Name it Foodgram with Xano

4.Click on the + button next to Requests to add a new request for each of the following 6 requests (NB the comes from step (B)2 above.

Signup

Name: Signup Type: POST Request URL: /auth/signup Headers : None Parameters: Key = email, Value = test@test.com Key = password, Value = passw0rdBody: { "email" : "${email}", "name" : "${email}", "handle" : "${email}", "password" : "${password}" }

Once you have setup the Signup Request, hit the blue send button for this request to add that user to Xano so we can setup the other requests.

Name: Login Type: POST Request URL: /auth/login Headers : None Parameters: Key = email, Value = test@test.com Key = password, Value = passw0rd Body: { "email" : "${email}", "password" : "${password}" }

Once you have inputted the above hit the blue send button for this request to get sample data to allow the received data to be setup for this request.

Make sure the .data.authToken field is ticked and then in the Selected Data tab change the field’s name to auth-token. We can reference this name as a variable in other requests to allow the request to pass authentication.

Add photo

Name: Add photo Type: POST Request URL: /photo Headers : Key = Authorization, Value = Bearer ${auth-token} Parameters: None Body: { "caption" : "${caption}", "image_url" : "${image_url}", "tags" : "" }

Get all photos

For this step we will need the auth token form step (B) 8, to enable us to highlight the data we need.

Name: Get all photos Type: GET Request URL: /photo Headers : Key = Authorization, Value = Bearer ${auth-token} Parameters: Key = auth-token, Value = <Auth Token from step (B)8> Body: None

Once you have inputted the above hit the blue send button for this request to get sample data to allow the received data to be setup for this request.

Make sure the following fields are ticked in the Received data pane , .data.items[], .data.items[].id, .data.items[].caption, .data.items[].image.url, .data.items[].user.handle. Then change the name of the .data.items[].id field to photo_id. (NB this name photo_id needs to be consistent, i.e. not photo-id throughout the queries as its is used by the app to reference the particular photo for comments etc),

Add comment

Name: Add comment Type: POST Request URL: /comment Headers : Key = Authorization, Value = Bearer ${auth-token} Parameters: Key = auth-token, Value = <Auth Token from step (B)8> Key = comment, Value = Test Comment Key = photo_id, Value = 1 Body: { "comment" : "${comment}", "photo_id" : "${photo_id}" }

Once you have inputted the above hit the blue send button for this request to create a test comment to help with the comment setup.

Get photo comments

Name: Get photo comments Type: GET Request URL: /comments/${photo_id} Headers : Key = Authorization, Value = Bearer ${auth-token} Parameters: Key = auth-token, Value = <Auth Token from step (B)8> Key = photo_id, Value = 1 Body: None

Once you have inputted the above hit the blue send button for this request to get sample data to allow the received data to be setup for this request.

Make sure the following fields are ticked in the Received data pane, .data.items[], .data.items[].id, .data.items[].comment , and .data.items[].user.handle .

Now all the APIs are now setup in Bravo and we just have to connect them to the design.

E) Bind the APIs to the design in Bravo

Now that we have the APIs in Bravo the last step is to connect them to the app design. Go into the Foodgram with Xano app so you can see all the screens.
