Features

• Simplified result, so you don't need to deal with complex objects and arrays.
• Automatic data recognition, whether it's Base64, a Data URL, or a URL.

Example

var virusNsfw = require('virus-nsfw');

var filter = new virusNsfw.Filter("YOUR_CLARIFAI_API_KEY_HERE");

function handleResult(result) {
    if (result.sfw) {
        console.log(`This image is A-OK with a confidence of ${result.confidence}.`);
    } else {
        console.log(`This image is NSFW with a confidence of ${result.confidence}.`);
    }
}

function handleError(error) {
    console.error(error);
}

filter.get("https://example.com/example.png").then(handleResult).catch(handleError); // URL
// or // 
filter.get("data:image/png;base64,dGhpc2lzbm90YW5pbWFnZQ==").then(handleResult).catch(handleError); // Data URL
// or // 
filter.get("dGhpc2lzbm90YW5pbWFnZQ==", handleResult).then(handleResult).catch(handleError); // Base64

Setting up your project

First, you'll need to install virus-nsfw via NPM. Use the --save-dev flag, so it gets saved into your package.json file.

npm install --save-dev virus-nsfw

Or without save into devDependencies

npm install virus-nsfw

First, you'll need to require and initialize FILTER in your code. Use require('virus-nsfw'), and then, you'll need to create a new FILTER instance. Here's where your API key comes in.

For security reasons, you shouldn't hardcode your API key into your code, because if you upload it to GitHub, or someone gets the code, they can just read out the key. What we recommend, is storing it in your environment variables. You know, that place where PATH, and stuff like that is.

Go ahead and save your API key in an environment variable. Now, when you push the code to GitHub, or upload is somewhere, people can't see it.

After you've securely saved your API key into an environment variable, we can create the virus-nsfw instance. Use new Filter(process.env.YOUR_ENVIRONMENT_VARIABLE_NAME_HERE) for that.

var { Filter } = require('virus-nsfw');

var filter = new FILTER(process.env.MYAPP_CLARIFAI_KEY);

Or you can do else 

var Nsfw = require("virus-nsfw")
var filter = new Nsfw.Filter(process.env.MYAPP_CLARIFAI_KEY)

Congratulations! Now you can predict the NSFWness of images. Let's see an example of how to do that!

var { Filter } = require('virus-nsfw'); 
var filter = new Filter(process.env.MYAPP_CLARIFAI_KEY);
/**
you can do else 
var Nsfw = require("virus-nsfw")
var filter = new Nsfw.Filter("your key")
*/
filter.get("https://example.com/image.png").then(function(result) {
    if (result.sfw) { // If the result is safe for work:
        console.log(`This image is safe for work, with a confidence of ${result.confidence}!`);
    } else { // If the result is not safe for work:
        console.log(`This image is not safe for work, with a confidence of ${result.confidence}!`);
    }
}).catch(function(error) {
    console.error(error); // Print the error to the console.
});
