How To Create Language Detection Using An AI-Powered API?

The difference between a really successful application and one not so successful is often the number of languages it can support. in fact, having multi-language support in your software makes your application much more likely to be welcomed by millions of people around the world.

LanguageLayer is one of the market-leading language detection RESTful web services. LanguageLayer is powered by AI and also supports 173 languages. Using ip geolocation can also be useful to location a user’s country.

How to do batch detection?

The LanguageLayer API also processes multiple query texts in a single API request. To make use of this feature, simply include the API’s batch endpoint and pass a series of the query into the API request URL:


After executing this batch request, the API returns single or multiple language detection results for each requested query text. Languagelayer returns results in the same order you specified in the API request. 

How to start a Node.js web app?

In this demonstration, we will create a simple Node.js app that fetches data from the LanguageLayer API and shows it to a user.

Open your PowerShell or Bash if you are using Linux and type these commands to set up basic files for the project:

Now, go back to your terminal and write these commands to install the packages our project requires. It installs Express, axios and body-parser, as well as EJS.


Next, make sure you have these files and project folder structure.

Here is our Node.js web app source code:

Finally, this is the result:

It really is that simple to autodetect languages. Want to see more or try it yourself? Check out the whole project in this repository.
