vazco/Listing Query Manager

 

-- Abandonware. This package is deprecated! --

 

This utility allows you to handle repetitive tasks related to fetching data for listing: state management, url parsing, validation. It keeps state in url, and transforms it to two additional formats:

1. Url - pretty and customizable formating e.g.

    /my-listing?sort=created-desc&name=Donald%20T

2. Params - ready to pass as argument to server call. Only allowed fields will pass e.g.

    MyQuery.toQuery();
    // => {
    //     sort: 'created-desc',
    //     filter: {
    //         name: 'Donald T'
    //     }
    // }

2. Mongo query - ready to pass to mongo find(). Define your default regex pattern once and use it across whole project e.g.

    MyQuery.toMongo();
    // => {
    //     sort: {
    //         createdAt: -1
    //     },
    //     filter: {
    //         name: {$regex: `^.*Donald T.*$`}
    //     }
    // }

Usage

import {QueryManager} from 'listing-query-manager';

// client and server: Define query
const ItemsQuery = QueryManager.define({
    filter: {
        title: 'regex',
        authorId: 'eq'
    },
    sort: {
        created: 'createdAt',
        title: 'title',
    }
});


// client: subscribe and get data
Meteor.subscribe('items', {
    query: ItemsQuery.toQuery()
}, function () {
    const {filter, sort} = ItemsQuery.toMongo();

    Items.find(filter, {sort});
});

// server: get data
Meteor.publish('items', function ({query}) {

    const {filter, sort} = ItemsQuery.toMongo({query});

    Items.find(filter, {sort});

    return cursor;
});

// client: handle sorting by render clickable labels
class Listing extends React.Component {
    render () {
        return (
            <ClickToSort name="name" queryParams={queryParams}>
                Name
            </ClickToSort>
            <ClickToSort name="createdAt" queryParams={queryParams}>
                Created At
            </ClickToSort>
        );
    }
}

// client: handle filtering

ItemsQuery.setFilter({
    name: 'Donald T'
});
