Read image from disk

- [Instructor] So with our basic project written…now let's go ahead and start writing custom logic.…Logic that allows me to make a request…to the Vision API, read a file from the file system,…authenticate, and get the results back.…Let's see how.…So the only file that I'm interested…in here is the index.ts.…So let me close everything else…and focus only on index.ts.…And I'd like you to remember that there is a file here…called config.tx where we have the endPoint and key.…

We will find that very useful shortly…but for now let's focus on index.ts.…So at a very high level, I'm going to need a function…call readImage which will go to the file system…and it will read an image from the file system…and provide it to me as a buffer.…So I'm going to go ahead and import…* as fs from the fs object, which is part of Node.js…And I'm also going to import Buffer,…which is also part of node Node.js, excellent.…

Next here I'm going to say const fileData…is fs.readFile, let's just go with Sync,…we're trying to keep things simple here…
