Read Operations

Get by ID

JavaScript

// MongoDB

db.collection("Users")
  .id("7b5f87cfb6ce44f98c82a1c6")
  .then(result => {
     if(result.success)
     {
        const user = result.doc;
     }
     else
     {
        // handle error
     }
  })
  
// MySQL

db.table("Users")
  .id("7b5f87cfb6ce44f98c82a1c6", "UserID")
  .then(result => {
     if(result.success)
     {
        const user = result.doc;
     }
     else
     {
        // handle error
     }
  })

Flutter

collection("users") and table("users") is interchangable and has the same effect. Appstitch offers a linguistic convention for both the NoSQL and SQL world

Get multiple documents

JavaScript

// MongoDB

db.collection("Users")
  .where("City", "==", "NewYork")  
  .then(result => {
     if(result.success)
     {
        const user = result.doc;
     }
     else
     {
        // handle error
     }
  })

Flutter

Write Operations

Insert

JavaScript

db.collection("Users")
    .insert({name : "Bruce", city : "Gotham"})
    .then(result => {
        if (result.success) {
            const userID = result.id;
        } else {
            // handle error
        }
    })

Flutter

Update

JavaScript

const result =  db
               .collection("users")
               .doc(userID)
               .update({city : "New York"})
               .then(result => {
                 if (result.success) {
                   // success 
                 } else {
                     // handle error
                 }
               })

Flutter

Delete

JavaScript

const result =  db
               .collection("users")
               .doc(userID)
               .update({city : "New York"})
               .then(result => {
                 if (result.success) {
                   // success 
                 } else {
                     // handle error
                 }
               })

Flutter

Algolia Integration

Appstitch can be used to keep your Algolia indices in sync. Just pass syncData with any write operation.

The Algolia index will need to have the identical name (and case) as your collection/table

Algolia example

JavaScript

db.collection("Users")
    .insert(
    {name : "Bruce", city : "Gotham"}, 
    {syncData : true} // <-- User will be created in Algolia 
    )
    .then(result => {
        if (result.success) {
            const userID = result.id;
        } else {
            // handle error
        }
    })
