Jexia documentation

# Interact with data

# Install SDKs

  • JavaScript
  • Python
  • cURL 
npm install jexia-sdk-js node-fetch ws --save

# Make request

Now let's make simple CRUD to access our Dataset. For this, you can use the REST API or one of our SDKs. Our JS SDK is built on top of the RxJS library, so you can use all the power of this library. Other SDKs can be found on our GitHub.

  • JavaScript
  • Python
  • cURL

Below you can see an example with all the modules imported from SDK. If you do not need to access Filesets, Project Users (UMSModule) or real-time events, feel free to skip importing them.

import {
  jexiaClient,
  dataOperations, // To work with Datasets
  fileOperations, // To work with Filesets
  UMSModule, // To work with Project Users
  realTime // To get real-time notification for data changes and work channels
} from "jexia-sdk-js/node";

const ds = dataOperations();
const jfs = fileOperations();
const ums = new UMSModule();
const rtc = realTime();

// You need to use your API Key / API Secret which is generated within your Jexia application.
// Do not forget to create a Policy for your API and set the proper restrictions!

// In addition to key and secret, you need to provide either projectID and zone OR just provide projectURL
jexiaClient().init({
  projectID: "PROJECT_ID",
  key: "API_KEY",
  secret: "API_SECRET",
  /**
   * Zone parameter was introduced in v5.2.0
   * If your project uses a previous version it will keep working for a while.
   * You can find you project zone inside "Settings" section of your project.
   */
  zone: "PROJECT_ZONE",
}, ds, /* pass any other modules you need like jfs, ums, rtc */);

// or

jexiaClient().init({
  projectURL: "PROJECT_URL", // you can find it in your project settings
  key: "API_KEY",
  secret: "API_SECRET",
}, ds);

// Now you can run any CRUD operations for your Datasets
const orders = ds.dataset("orders");
const archive = ds.dataset("arch");
const selectQuery = orders
  .select()
  .where(field => field("dislike").isEqualTo(true));

// const insertQuery = orders.insert([order1, order2]);
// const updateQuery = orders.update([{ title: "Updated title" }]);
// const deleteQuery = orders.delete();

selectQuery.subscribe(records => {
    // You will always get an array of created records, including their
    // generated IDs (even when inserting a single record)
  },
  error => {
    // If something goes wrong, you'll get an IRequestError object
});

# Work from browser

You can work with Jexia platform directly from browser. For this you need to import Jexia SDK through unpkg

<html>
<head>
     <script src="https://unpkg.com/jexia-sdk-js/bundle/browser.umd.min.js"></script>
</head>

and then do similar commands to get data. Below you can find example:

<html>
<head>
     <script src="https://unpkg.com/jexia-sdk-js/bundle/browser.umd.min.js"></script>
</head>
<body>
<i>loading...</i>
<ul></ul>
<script type="text/javascript">
  window.onload = function() {
    if (!jexia) {
      throw new Error("Please inform support team of Jexia.");
    }
    // Initialize dataOperationsModule
    const dataModule = jexia.dataOperations();
    const credentials = {
      projectID: "<your-project-id>",
      key: "<your-project-api-key>",
      secret: "<your-project-api-secret>",
      zone: "<your-project-zone>",
    };
    jexia.jexiaClient().init(credentials, dataModule);
    const postsList = document.querySelector("ul");
    dataModule.dataset("posts")
      .select()
      .subscribe(
        (posts) => {
          posts.forEach((post) => {
            const postTitle = document.createElement("li");
            postTitle.innerText = post.title;
            postsList.appendChild(postTitle);
          });
        },
        (errors)=>{console.log(errors)}
      )
  }
</script>
</body>
</html>
