Step-0

In this step, we will setup our project and create an Azure Function to get Twitter Search data into our application. You can follow the below steps or check out "step-0" branch of this repo.

• Download

• Node.js latest LTS version. Latest Node is not compatible with the tools we are using and not recommended for most users.

• Visual Studio Code 2019

• Visual Studio Code Azure Extensions or Azure Functions Extension

• Sign up for a free Azure account

• Select Azure Extensions from VS Code left hand panel.

• Select Functions grouping, click on folder icon on the Functions grouping to create a new project. Select a folder or create a new folder for your project repository.

• To create a function select the second icon on the Functions grouping.

• You will be prompted to sign in if you have Azure Tools or Azure Repos extensions.

• When prompted, name your function "SearchTweets". Language "TypeScript".

• When prompted, select "Anonymous". This will make our API public.

• Azure Functions Extension will create our initial configuration files as well as SearchTweet folder with our first Azure function.

• To run the code you can open up the internal terminal from the Command Palette (P), use the View: Toggle Integrated Terminal command.

• Run npm start script

npm run start

• Start script will download extensions configured in your 'functions.json' file and start a serve your project.

• In your terminal, you will see a localhost link 'http://localhost:7071/api/SearchTweets'. Click the link to open in a browser.

• You will see the error message being displayed. This message is set on 'SearchTweet/index.ts' file.

• Add a name query value to see the message returned.

http://localhost:7071/api/SearchTweets?name=aysegul

Step-1

Adding Twitter Api: we will add twitter authorization and search functionality. We will refactor our code to make sure when the our projects gets bigger, it is still maintainable and structured well.

• Sign up for Twitter Developer Api

• We will be using the standard search api. Add tokens and secrets as well as the search url we will be calling to local.settings.json file.

{
    "consumer_key": "fs54YbjfXuQWJRs01XatGR",
    "consumer_secret": "lzXoL4GzxGYeItJ327BGcNmZcmPhgjgft62x0tHuZYmad",
    "access_token_key": "35870660-0250Io0UYm5NHtutgM7bq57h9aChvA30FIBYV0j1q",
    "access_token_secret": "RFab22sgMgg9DlwoWRZrQRIizQZultYvo2Ek9C0Xp",
    "search_url": "https://api.twitter.com/1.1/search/tweets.json"
}

You can add your keys in any other structure if you like. I can reach to my keys from my functions as:

process.env.Twitter.consumer_key;

• Authentication: we will use application-only authentication. Application-only authentication offers applications the ability to issue authenticated requests on behalf of the application itself (as opposed to on behalf of a specific user). We need to acquire bearer token using our consumer key and secret.
