In this article, you are going to learn about how to build a sticky note app using html,css and javascript. You're going to store the notes in Api and get the notes from api for display in the screen.
Here are four steps we will follow to build sticky note app:
- Set up html structure and css
- Create form to capture note
- Post note to Api
- Get notes from Api
To follow along with this tutorial, you'll need to be familiar with the following:
- html and css
- javascript and dom manupilation
- fetch api
NOTE: In this tutorial you will use mock api to store notes.
1. Set up html structure and css
Create index.html
file and link it to style.css
file. Add the following html code to index.html
.
NOTE: The follow html code, also link index.js
file
<head>
<!-- link style.css file -->
<link rel="stylesheet" href="./style.css" />
<title>my notes</title>
</head>
<body>
<main>
<header>
<h1>My Notes</h1>
<a id="display-form-input"
class="Add-new-note-btn">+ Add a new note</a>
</header>
<section id="note-section" class="main-article-section">
<div id="article-div" class="flex-section-div"></div>
</section>
</main>
<script src="./index.js"></script>
</body>
Now create a style.css
file. Add the code below to style.css
file.
:root {
--head-color: hsla(0, 0%, 13%, 1);
--dark-blue: hsla(228, 69%, 13%, 1);
--blue: hsla(228, 69%, 20%, 1);
--content-color: hsla(0, 0%, 13%, 1);
--greyish: hsla(0, 2%, 44%, 1);
--white: hsla(0, 0%, 100%, 1);
}
body {
position: relative;
inline-size: 100%;
block-size: 100%;
font-family: "DM Sans", sans-serif;
background: var(--white);
display: flex;
flex-direction: column;
align-items: center;
justify-content: center;
padding: 0.8rem;
}
header {
display: flex;
align-items: center;
justify-content: space-between;
}
main {
inline-size: 90%;
}
.add-new-note-btn {
background-color: var(--dark-blue);
font-size: 16px;
line-height: 16px;
display: inline-block;
inline-size: 15%;
text-align: center;
text-decoration: none;
padding: 15px 24px;
color: var(--white);
border-radius: 25px;
margin-block-end: 1.5rem;
}
.submit-note{
padding: 15px 24px;
background:var(--dark-blue);
border-radius: 20px;
color: var(--white);
margin-block-start: 1rem;
inline-size: 40%;
margin-inline-start:60%;
border:none;
white-space: nowrap;
}
textarea{
resize: none;
padding: 0.7rem;
display: block;
inline-size: 310px;
block-size: 112px;
border-radius: 10px;
background:var(--greyish);
color: var(--white);
}
.note-div{
inline-size: 160px;
block-size: 120px;
background: #FCF5D2;
border-radius: 10px;
margin: 1rem;
padding: 0.4rem;
}
#note-section{
display: flex;
flex-wrap: wrap;
}
Run index.html
file in the browser. The code output should ressemble the image below.
2. Create form to capture note
Now user needs somewhere to type their note. In this section you will implement display form logic. When user clicks +Add new note
button, a form displays. Users can then type note in the textarea
. The steps below implements display form logic.
Create
index.js
file.Add click event listener to
+Add a new note
button. The code below handles the clicked event by callingdisplayForm
function.
const addNewNote = document.querySelector(".Add-new-note-btn");
addNewNote.addEventListener("click",function (event){
event.preventDefault();
displayForm()
})
function displayForm(){
const form = document.createElement("form");
form.setAttribute("id", "note-form");
// create textarea
const textArea = document.createElement("textarea");
textArea.setAttribute("id", "note");
textArea.setAttribute("placeholder","Add note");
// create add note button
const button = document.createElement("button");
button.setAttribute("class", "submit-note btn-state");
button.setAttribute("id", "add-note");
button.textContent = "Add note";
// add textarea and button element to form created
form.append(textArea, button);
document.body.appendChild(form);
}
- Run
index.html
file and clickAdd new note
button. The browser should resemble the image below.
3. Post note to Api
User is able to type the note in our application. But, the text vanishes when submitted. You need to prevent the default behavior of form submission. Then get note content and store the note in Api.
To store note in Api, follow the following steps:
- Add click event listener to
add note
button - Call
postNote
function passing inurl
as parameter
const postNoteBtn = document.querySelector("#add-note");
postNoteBtn.addEventListener("click", function (e) {
e.preventDefault();
postNote("https://64e507a7c555638029140f2a.mockapi.io/note");
});
NOTE: add note
button event listener, is added inside displayForm
function to prevent TypeError
messege(postNoteBtn is null) since the form to type text, is not yet displayed.
The postNote
function does the following:
- Gets user typed value.
- Creates new object(noteObject) with
content
as key - Assign typed value to
const noteObject = {content:typedValueFromUser};
- Post noteObject to Api using
fetch
method - Create new
div
html element - Assign
textContent
property of newdiv
to value obtained fromfetch
method - Append created
div
to a section element of idnote-section
inindex.html
- Remove the form element
function postNote(url) {
const note = document.getElementById("note").value;
let noteObject = { content: note };
// request object used in fetch api
const requestObject = {
method: "POST",
headers: {
"content-type": "application/json",
},
body: JSON.stringify(noteObject),
};
fetch(url, requestObject).then((response) => {
if (response.statusText == "Created") {
response.json().then((noteObj) => {
const div = document.createElement("div");
div.setAttribute("class", "note-div");
div.textContent = noteObj.content;
document.querySelector("#note-section").appendChild(div);
document.getElementById("note-form").remove();
});
}
});
}
4. Get notes from Api
You are able to post note to api. You are also able to display note in the browser. But when the browser loads, every note disappear. You need to get all notes displayed in the browser when browser loads.
Add load event listener to window object. When browser loads, it triggers fetchNote
function. fetchNote
function does the following:
- Gets all notes from Api in array form
- Create div for each note in the array
- Set
textContent
for each div to each note in array - Append each
div
to a section element of idnote-section
inindex.html
window.addEventListener("load", function fetchNote() {
fetch("https://64e507a7c555638029140f2a.mockapi.io/note").then((response) => {
if (response.statusText == "OK") {
response.json().then((notes) => {
notes.forEach((note) => {
const div = document.createElement("div");
div.setAttribute("class", "note-div");
div.textContent = note.content;
document.querySelector("#note-section").appendChild(div);
});
});
}
});
});
Great! Now you have created your own sticky note application. The end result for the sticky note resembles the image below
Conclusion
In conclusion, You've embarked on a journey to create a dynamic and engaging Sticky Note application using the fundamental web technologies of HTML, CSS, and Vanilla JavaScript, enhanced with API integration.Through this step-by-step tutorial, we've learned how to :
- Set up html structure and css
- Create form to capture note
- Post note to Api
- Get notes from Api
Remember there are endless possibilities for expansion. You can expand your sticky note app to edit and delete posted note.
