Vuejs Basic Tutorial part 1
1: Create Vue App, Template and Data
Create app.js file and paste below code
const app = Vue.createApp({
data(){
return {
title:"My first components",
age:29,
author:"Vishavjeet Singh",
languages:["Python", "JavaScript"]
}
}
});
app.mount("#app")
Create index.html file and paste below code
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=Test, initial-scale=1.0">
<title>Document</title>
<script src="https://unpkg.com/vue@3.0.2" ></script>
</head>
<body>
Hi vue js
<div id="app">
{{ title}} - {{ age}} - {{ author}} - {{ languages}}
</div>
<script src="app.js"></script>
</body>
</html>
2: Method and click events
- app.js
const app = Vue.createApp({
data(){
return {
title:"My first components",
age:29,
name:"Vishavjeet Singh",
languages:["Python", "PHP"]
}
},
methods:{
changeTitle(){
this.title = "Change title by changeTitle method"
},
changeTitleWithParam(title){
this.title =title
}
}
});
app.mount("#app")
- index.html
<div id="app">
<button v-on:click="age++"> Increase Age by 1</button>
<button v-on:click="age--">Decrese Age by 1</button>
<button @click="title= 'Change title using assingment '"> Change title by attribute</button>
<button @click="changeTitle()"> Change title by changeTitle function without argument</button>
<button @click="changeTitleWithParam('My new title')"> Change title by changeTitle function with argument</button>
</div>
3: Conditinal rendering
- app.js
const app = Vue.createApp({
data(){
return {
title:"Core Python Book",
age:29,
author:"Vishavjeet Singh",
languages:["Python", "PHP", "JavaScript", "SQL", "CQL"],
showBook: true
}
},
methods:{
changeTitle(){
this.title = "Change title by changeTitle method"
},
changeTitleWithParam(title){
this.title =title
},
toggleShowBook(){
this.showBook = !this.showBook
}
}
});
app.mount("#app")
- index.html
<div id="app">
<div v-if="showBook">
{{ title}} - {{ age}} - {{ author }} - {{ languages}}
</div>
<button v-if="showBook">
<span @click="toggleShowBook()"> Hide Book</span>
</button>

<span> v-show </span>
</button>
</div>
# 4: Other Mouse Events - app.js
const app = Vue.createApp({
data(){
return {
x:0,
y:0
}
},
methods:{
handleEvent(e, data){
console.log(e, e.type)
if(data){
console.log("data found", data)
}
},
handleMouseMove(e){
this.x = e.offsetX
this.y = e.offsetY
}
}
});
app.mount("#app")
- index.html

<div class="box" @mouseleave="handleEvent($event)"> Mouse Over</div>
<div class="box" @dbclick="handleEvent"> Double click </div>
<div class="box" @mousemove="handleMouseMove"> Mouse Move: {{x}}, {{y}} </div>
</div>
</body>
5: output list v-for

print(f'Next Monitoring date will be {next_monitoring} or after {remaining.days} days')

Using Class

else:

while flag:
next_monitoring = next_monitoring + timedelta(days=self.frequency)
difference = next_monitoring - self.today_date
if difference.days >= 0:
flag = False
remaining = next_monitoring - self.today_date
return remaining.days, next_monitoring
def __str__(self):

return f'Next Monitoring date will be {next_monitoring} or after {remaining_days} days'
remaining_days = RemaningDayFinder("2022-04-15", 20) print(remaining_days)
Best Logic Based on Performance
def get_remaining_days(review_date, frequency): date_formate = '%Y-%m-%d' review_date = datetime.strptime(str(review_date), date_formate) today_date = datetime.strptime(str(datetime.now()).split(" ")[0], date_formate)
difference = today_date - review_date
if difference.days <= 0:
next_monitoring = review_date + timedelta(days=frequency)
else:
pass_days = ((difference.days//frequency)*frequency)+frequency
next_monitoring = review_date + timedelta(days=pass_days)
remaining = next_monitoring - today_date
print(f'Next Monitoring date will be {next_monitoring} or after {remaining.days} days')
return remaining.days, next_monitoring
