vertx-diff

This is a web application that makes a diff of two files.

  • If the files have the same length -> they are equal
  • If the files differ in length -> they are not equal
  • If the files have the same length and different content -> an array of position and offset will be returned indicating where the differences are

The files are stored in MongoDb that is started by using docker (instructions below). Docker runs on its default 27017 port and it must be started before running the application and the integration tests.

There are three endpoints:

  • POST http://localhost:4004/v1/diff/{id}/left -> to upload the left document
  • POST http://localhost:4004/v1/diff/{id}/right -> to upload the right document
  • GET http://localhost:4004/v1/diff/{id} -> to make the diff

In the POST methods the body must be application/json and have one attribute text. This attribute must have the text encoded in B64.

Starting MongoDB

$ docker pull mongo

$ docker run -d -p 27017:27017 mongo

Running the tests

$ mvn clean verify

This will run both unit tests and integration tests

Starting application

$ cd diff-app; mvn vertx:run
