Tips on sending data with a unique identifier to the backend through a route parameter

Can anyone help me figure out how to send a message to a specific backend route parameter while passing the current ID? I'm not sure how to inform the system about this ID.

Here's the Vuex action:

postMessage({commit}, payload, id) {
  axios.post(`http://localhost:5000/channels/${id}/messages` ,payload)
    .then((res) => {
      commit(SET_POSTS, res.data)
    })
}

The above code is able to post the action, but I am struggling with passing the channel ID which is located in a different component. How can I achieve this?

postMessage() {
  const postData = {
    description: this.description,
    timestamp: this.timestamp
  };
  this.$store.dispatch("postMessage", postData)
},

In another component, I have a sidebar menu displaying a list of channels similar to Discord. Here's how it looks like:

 p.d-flex.align-items-center.channel-item(v-for="channel in channelName" :key="channel.id")
      strong.hash.mr-3 #
      | {{channel.channel_name}}

One of the main advantages of utilizing Vuex is its capability to establish state in one component and retrieve it from another component. In the receiving component, set a particular state like state.id. Subsequently, you have the option to either pass that id to the action or extract it directly from state within the action.

Below is an example demonstrating how to pass it:

Method

postMessage() {
  const postData = {
    id: this.$store.state.id,
    description: this.description,
    timestamp: this.timestamp
  };
  this.$store.dispatch("postMessage", postData)
}

Vuex actions always expect only 2 parameters - one for the context object (containing commit, dispatch, etc.) and the payload. Adjust your action as follows:

Action

postMessage({ commit }, payload) {
  axios.post(`http://localhost:5000/channels/${payload.id}/messages`, payload)
    .then((res) => {
      commit(SET_POSTS, res.data)
    })
}

If desired, you can opt to destructure the payload argument and utilize the spread operator to separate the id from the rest:

Action

postMessage({ commit }, { id, ...payload }) {
  axios.post(`http://localhost:5000/channels/${id}/messages`, payload)
    .then((res) => {
      commit(SET_POSTS, res.data)
    })
}

An alternative approach would be to exclude the id from the payload and instead retrieve it directly from the state within the action:

Action

postMessage({ state, commit }, payload) {
  axios.post(`http://localhost:5000/channels/${state.id}/messages`, payload)
    .then((res) => {
      commit(SET_POSTS, res.data)
    })
}
