Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

<img src="http://lucene.apache.org/solr/assets/identity/Solr_Logo_on_white.png"width="100"/> sails-solr

Provides easy access to solr from Sails.js & Waterline.

This module is a Waterline/Sails adapter, an early implementation of a rapidly-developing, tool-agnostic data standard. Its goal is to provide a set of declarative interfaces, conventions, and best-practices for integrating with all sorts of data sources.

The main goal is a simple usage and integration of a full managaged Solr.

NPM

Installation

To install this adapter, run:

$ npm install sails-solr

Getting started with sails-solr

To install/start solr if you not have one running

make kickstart

Note: not recommended for production systems! Solr installation Tomcat for more

Configuring Connections

Add the solr configuration to the config/connections.js file. The basic options are as follows:

module.exports.connections = {
  solrConnectionOne: {
    module : 'sails-solr',
    host: 'localhost',
    port: 8983,
    core: 'schemaless',
    schema: true,
    migrate: 'drop'
  }
};

Note: you can define multiple solr connections/cores. By default sails-solr will run multiple models inside one core manageCores. Connection Options

Configuring Models

And then change default model configuration to the config/models.js:

module.exports.models = {
  connection: 'solrConnectionOne',
  attributes: {
    name:'string'
    ...
  }
};

Note: you can add more model based configuartion Model Options / Connection Options

Usage

create a user:

  User.create({name:'foo'},console)

find a user:

  User.find({name:'foo'},console);
  User.findOne({name:'foo'},console);
  User.findByName('foo',console);

Note: See Waterline Documentation Query Language and Query Methods

Special Adapter Interfaces

Autocompleter

search suggestion and spellchecked phrase. Known as "Did You Mean: foo?"

Layerd Navigation

Well known as filter. facet for strings and min,max,avg for ìnteger to build Options and Range Slider Elemets. Query Methods

Field Type Map

The following table represents mappings between Sails/Waterline model data types and Solr field types:

Note: You can even define your custom mapping as fieldTypeMap: inside connection settings and as model option. If you want a field type explicit mapping use fieldType as additional fieldTypeMapattribute

Solr default field attributes

The following table represents Solr field attributes:

| Solr Field Attributes | Default | |:-------------------------|:-------------| | name | newField | | type | text_general | | indexed | true | | stored | true | | docValues | false | | sortMissingFirst | false | | sortMissingLast | false | | multiValued | false | | omitNorms | true | | omitTermFreqAndPositions | false | | omitPositions | false | | termVectors | true | | termPositions | false | | termOffsets | false | | termPayloads | false | | required | false | | dynamicField | false | | json | text_general |

Note: You can even define your custom field attribute default as schemaDefaultFieldAttributes: inside connection settings and as model option. If you want a field attribute explicit you can add this attribute as an additional option inside the Model attribute settings
