Odoo is a powerful open-source management software with a wide range of applications to simplify various business processes. A key feature of Odoo is its JavaScript framework, which allows developers to create custom web interfaces and improve user experience. However, as with any software, the quality of the work is important for the work to be efficient and effective. In this blog post, we will explore some tips and optimizations for working effectively with Odoo JS.
Minify and Bundle JavaScript Files:
One of the simplest yet effective ways to improve Odoo JS performance is to minify and bundle JavaScript files. Shrinking reduces the size of files by removing unnecessary spaces, comments, and renaming variables to shorter names. Bundling combines multiple JavaScript files into a single file, reducing the number of requests and increasing loading speed.
Use Odoo's Built-in Caching Mechanisms:
Odoo provides several caching mechanisms that can improve performance. Take advantage of caching options such as server-side caching, browser caching, and CDN caching. Server-side caching reduces processing time by storing frequently accessed data in memory. Browser caching allows the user's browser to store static files locally, reducing the need for repeated downloads. A content delivery network (CDN) cache reduces latency for users in different regions by statically distributing data to multiple servers around the world.
Lazy Loading:
Lazy loading is a technique that delays the loading of non-critical resources until they are needed. Implement lazy loading for images, videos, and other heavy assets to improve initial page load times. Odoo provides lazy loading mechanisms that can be used to load components dynamically as the user interacts with the interface, reducing the initial payload.
Here is an example of how to use late loading of content in Odoo JS using Odoo JS Core:
odoo.define('your_module_name.lazy_loading', function (require) {
"use strict";
var core = require('web.core');
var ListController = require('web.ListController');
var _t = core._t;
ListController.include({
renderPager: function () {
var self = this;
return this._super.apply(this, arguments).then(function () {
if (self.$pager && self.$pager.hasClass('o_lazy_loading')) {
self.$pager.find('.o_lazy_load').waypoint(function () {
self.loadMore();
}, {
offset: '100%'
});
}
});
},
loadMore: function () {
if (this._infiniteLoading) {
return;
}
var self = this;
this._infiniteLoading = true;
// Perform your lazy loading logic here
// For example, fetch more records from the server
// Once new records are loaded, append them to the view
// using the `append` or `prepend` method
// Example:
/*
this._rpc({
model: 'your.model',
method: 'load_more',
args: [],
}).then(function (result) {
// Process the result and append the new records to the view
self.$('.o_list_view').append(result);
self._infiniteLoading = false;
}).fail(function () {
self.displayNotification({
title: _t('Error'),
message: _t('Failed to load more records.'),
type: 'danger',
});
self._infiniteLoading = false;
});
*/
},
});
});In this example, we extend ListController in Odoo JS Core to implement the late loading of items. The renderPager function is called when the page has been rendered and has the class o_lazy_loading. In this function, we initialize the waypoint extension for the loadMore() function with the waypoint() method when the element reaches 100% in the viewport. The loadMore() function handles the slow load logic. You can customize this function according to your needs.
Optimizing performance with Odoo JS is crucial to providing responsive service to users. You can improve the performance of your Odoo app by following the tips and tricks outlined in this blog post. Be sure to regularly define and monitor performance metrics to detect and further improve inconsistencies. With the effectiveness of the Odoo JS application, you can offer effective business solutions to your users.
