about vue-cli 3.x main.js

Question

In vue-cli 2.x, when you create a vue object in main.js, I remember that the template option was available.

In vue-cli 3.x, however, using the template option causes an error and you must use the render function.

I wonder why.

Answer 1

vue ui execute project preset add/remove(project setting) runtimeCompiler : true setting

or vue.config.js write

module.exports = {
runtimeCompiler: true
}
