1.Managing 2.Monitoring 3.Scaling MongoDB Realm is a set of whole Bunch of Features : Users & Authentication MongoDB Data Access Sync GraphQL API Functions Triggers Services Static Hosting Values & Secrets Application Management
The serverless platform from MongoDB
Functions : Run your Javascript code server-side, within the Realm serverless backend. Realm transparently scales to meet your usage
Triggers : Executes functions according to a schedule, or in real time in response to changes in the database or user authentication events.
Rules : Declratively control which fileds a user can access by defining simple JSON rules or Javascript functions
Services : Third-party services, such as Twilio can easily be referenced in the client.
Static Hosting : Run your entire web application on MongoDBRealm and MongoDB Atlas
Example : 1
const userAction = async () => {
let cust = await document.getElementById('myInput').value;
let txt = "";
let account_txt = "";
let img = "https://www.clipartkey.com/mpngs/m/96-966685_contact-person-icon-png.png"
console.log(cust);
const resp = await axios({
url: 'https://realm.mongodb.com/api/client/v2.0/app/bankingdongs-jbwjq/graphql',
method: 'post',
headers: {
'Authorization': `Bearer ${user.auth.activeUserAuthInfo.accessToken}`
},
data: {
query: `
query {
customer (query: {name: "${cust}"}){
name
email
address
accounts {
account_id
products
}
}
}
`
}
})
console.log(resp);
// IF Dog Quote is hit
if(resp.data.data.DogAndQuote){
txt = `${resp.data.data.DogAndQuote.quote} <br> - ${resp.data.data.DogAndQuote.author}`;
img = resp.data.data.DogAndQuote.dogImage;
showElement("quote")
}
}
<form method="POST" onsubmit="userAction()" action="javascript:">
<input type="text" onsubmit="userAction()" autocomplete="off" id="myInput" class="form-control" placeholder="customer name..." style="font-size: 2em; order:none">
</form>
