Loading

Start by forking this repository so it is available in your profile at https://github.com/\<your handle>/news-summarizer by clicking the fork button in github.

Log10

Go to https://log10.io/signup and create an organization, if you don't already have one.

Once you get to the on-boarding screen, click the "Summary grading" example feedback task.

This should redirect you to the feedback screen in Log10. To get your credentials, the fastest way is to click "add feedback".

Save the credentials in the instructions when setting up the modal backend.

These will go in the LOG10_URL, LOG10_ORG_ID and LOG10_TOKEN environment variables.

OpenAI

Sign up with OpenAI, if you don't already have an account here or login.

Go to the API keys page and create a key and save it for later. This will go in the OPENAI_API_KEY environment variable.

NewsAPI

Create a NewAPI key here ans save it for later. This will go in the NEWS_TOKEN environment variable.

Modal

Start by creating a secret that ensures that only your frontend can access your modal endpoint:

$ uuidgen

Save this value, or make up your own secret. This will go in the MODAL_SECRET environment variable.

Then create an account in modal here.

Secrets

At this point, you should have the values for the following secrets:

Name	Description
MODAL_SECRET	Secret key that protects your modal endpoint
LOG10_URL	API URL for Log10. NOTE Do not include trailing slash
LOG10_ORG_ID	Your Organization ID in Log10. This is an UUID and not the slug i.e. short name
LOG10_TOKEN	Your API token to log10
NEWS_TOKEN	Token for newsapi.org account
OPENAI_API_KEY	Your openai key

When you have logged in, click the secrets tab and click "Create new secret"

Then click "Custom":

And create secrets for log10, openai and the newsapi:

Then, name the secret "news-secrets":

And finalize the secret creation.

Installing modal and deploying service

$ cd service
$ virtualenv venv
$ . ./venv
$ pip install -r requirements.txt
$ python3 -m modal setup
# Follow instructions to log into your modal account
$ modal deploy main.py

This should print out something like:

✓ Created objects.
├── 🔨 Created mount /Users/niklasqnielsen/workspace/log10/news-summarizer/service/main.py
└── 🔨 Created fastapi_app => https://<your handle>--news-summarizer-fastapi-app.modal.run
✓ App deployed! 🎉

Note down the https://<your handle>--news-summarizer-fastapi-app.modal.run for setting up vercel.

Vercel / Web app

Log in with your github credentials here, and click "Add new..." and select "Project".

Now set the modal endpoint and secret that you noted above in the environment variable list, and click deploy.

After the site has been deployed, you should now be able to go to the vercel url and see the new summarizer.
