Loopback ilike - JavaScript

Loopback ilike is a plugin for the Loopback framework that enables case-insensitive search for string fields. This plugin can be used in any application built on top of the Loopback framework, and it is a powerful tool for developers who need to perform database queries based on user input.

Installation

To install Loopback ilike, you can use npm:

npm install loopback-connector-postgresql
npm install loopback-connector-mysql
npm install loopback-connector-mongodb
npm install loopback-connector-remote
npm install loopback-ilike-mixin

Usage

Once you have installed Loopback ilike, you can use it in your models. First, you need to enable the mixin in your model's definition:

{
  "mixins": {
    "Ilike": true
  }
}

Once the mixin is enabled, you can use the ilike operator in your queries:

MyModel.find({
  where: {
    fieldName: { ilike: searchString }
  }
}, function(err, results) {
  console.log(results); // will return all rows where fieldName matches the search string case-insensitively
});

You can also use ilike in remote methods:

MyModel.remoteMethod('search', {
  accepts: [
    { arg: 'searchString', type: 'string' },
    { arg: 'limit', type: 'number' },
    { arg: 'offset', type: 'number' }
  ],
  returns: { arg: 'results', type: 'array' },
  http: { path: '/search', verb: 'get' }
});

MyModel.search = function(searchString, limit, offset, callback) {
  var filter = {
    where: {
      fieldName: { ilike: searchString }
    },
    limit: limit,
    offset: offset
  };
  MyModel.find(filter, function(err, results) {
    if (err) return callback(err);
    callback(null, results);
  });
};

Conclusion

Using Loopback ilike in your application can greatly improve the search functionality of your application, without requiring complex query logic. By enabling case-insensitive search, your users will be able to find the data they need more easily, and you'll be able to focus on other aspects of your application.
