I want to know if that is the correct way i do it.
Firstly i fetch the hard coded data from my API and display it into the screen. I also have a form from which i send data and i want the axios.get method to instantly fetch the newest updated data that was sent from a form. I made a helper state that is put in to "useEffect array dependencies" and whenever that state changes its value, app reloads and fetches again.
Context file with useEffect hook:
import { createContext, useState, useEffect } from "react";
import { apiService } from "../services/api/api.service";
const Context = createContext({
footer: false,
subjectForm: false,
storedSubjects: [],
footerVisibilityHandler: () => {},
subjectFormVisibilityHandler: () => {},
});
export const ContextProvider = ({ children }) => {
const [footer, setFooter] = useState(false);
const [subjectForm, setSubjectForm] = useState(false);
const [storedSubjects, setStoredSubjects] = useState([]);
const [send, setSend] = useState(false);
useEffect(() => {
const getData = async () => {
try {
const getSubjects = await apiService.getSubjects();
const tableRow = getSubjects.data.map((subject) => {
return {
name: subject.name,
};
});
setStoredSubjects(tableRow);
} catch (err) {
console.log(err);
}
};
getData();
}, [send]);
const footerVisibilityHandler = () => {
setFooter((previousState) => !previousState);
setSubjectForm(false);
};
const subjectFormVisibilityHandler = () => {
setSubjectForm((previousState) => !previousState);
};
const context = {
footer,
subjectForm,
storedSubjects,
footerVisibilityHandler,
subjectFormVisibilityHandler,
setSend,
};
return <Context.Provider value={context}>{children}</Context.Provider>;
};
export default Context;Form from which i send data:
import Context from "../../store/context";
import FormContainer from "../UI/FormContainer";
import { apiService } from "../../services/api/api.service";
import { useContext, useRef } from "react";
const AddSubject = () => {
const ctx = useContext(Context);
const subject = useRef("");
const sendData = (e) => {
e.preventDefault();
ctx.setSend((prevState) => !prevState);
apiService.addSubject(subject.current.value);
};
return (
<FormContainer show={ctx.subjectForm} send={sendData}>
<label htmlFor="subject">Subject Name: </label>
<input type="text" id="subject" ref={subject} />
<button type="submit">Add</button>
</FormContainer>
);
};
export default AddSubject;Api endpoints file:
import axios from "axios";
const api = () => {
const baseUrl = "https://localhost:5001/api";
let optionAxios = {
headers: {
"Content-Type": "multipart/form-data",
},
};
return {
getSubjects: () => axios.get(`${baseUrl}/subjectcontroller/getsubjects`),
addSubject: (subjectName) =>
axios.post(
`${baseUrl}/subjectcontroller/createsubject`,
{
name: subjectName,
},
optionAxios
),
};
};
export const apiService = api();
