How to Convert EML to JPG in Node.JS

Today we are going to be taking a quick look at how to solve the problem of converting EML format, specifically into JPG images. Normally this would require a bunch of HTML parsing, rendering, rasterizing, etc. What a pain all of that is, let me tell you. So in the name of keeping things simple, we shall instead make use of an API, shaving off hours from our implementation time.

So we shall begin with client installation, as so:

npm install cloudmersive-convert-api-client --save

Now we call convertDocumentEmlToJpg, which looks like this.

var CloudmersiveConvertApiClient = require('cloudmersive-convert-api-client');var defaultClient = CloudmersiveConvertApiClient.ApiClient.instance;// Configure API key authorization: Apikeyvar Apikey = defaultClient.authentications['Apikey'];Apikey.apiKey = 'YOUR API KEY';// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)//Apikey.apiKeyPrefix = 'Token';var apiInstance = new CloudmersiveConvertApiClient.ConvertDocumentApi();var inputFile = "/path/to/file"; // File | Input file to perform the operation on.var opts = {'quality': 56 // Number | Optional; Set the JPEG quality level; lowest quality is 1 (highest compression), highest quality (lowest compression) is 100; recommended value is 75. Default value is 75.};var callback = function(error, data, response) {if (error) {console.error(error);} else {console.log('API called successfully. Returned data: ' + data);}};apiInstance.convertDocumentEmlToJpg(inputFile, opts, callback);

Done! Sooo easy.

There’s an API for that. Cloudmersive is a leader in Highly Scalable Cloud APIs.
