I think it is used as “this._vm.axios”, but did not work for me I have found this boot solution.
For one thing, you would need to access it as: this._vm.$axios because you put a $ in front on the prototype definition
Second, I don’t know how you are writing your functions but the this will be inforrect if you used fat arrow (=>) – they need to be functions for this to be referencing the store.
