Fake data when requesting vue?

Question

Vue.js

Maybe there is some library that, when requested. intercepts the answer and gives me the data from the file for example?
What is the best way to write the front, while the back is not ready, but you already know the data model?

Answer 1

Why a library? Decide on the data format and go ahead)))
Before developing the back, I just indicated json
Example:

mounted: function(){
    axios
      .get('http://localhost:8080/static/MainData.json')
      .then(response=>(this.MainData=response.data.filter(function(e){
        return e.Deadlines.length >0;
      })
      ))
      .catch(error=>console.log(error));
  },
