interface is left to redux to handle. The page just takes the data from redux.

consider Promise

I'm just writing a solution. I assume here that your A, B, C all return a promise, to do it using Promise.all, and the A, B, C you said is also used in interoperability, so what to do when interacting. Does not affect the initialization page.

componentDidMount() {
      const actionsCreators= [A,B,C]
      const promiseArr = []
      for (const v of actionsCreators) {
        promiseArr.push(dispatch(v))
      }
      Promise.all(promiseArr).then(() => {
          // 
      })
}
