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 🙏

CartoCC — Carto Config Customizer

Very simple tool for customizing layers values of a .mml config file.

Warning: it's experimental and work in progress.

Usage

For example, you may want to customize the database connection or some shp file path.

CartoCC makes it very simple. You just create some rules, stored in a json file, applying to layers fields. Each rule define some values to set to a layer if some field has some value.

Example of rules:

[
    {
        "if": {
            "Datasource.type": "postgis"
        },
        "then": {
            "Datasource.dbname": "osm2",
            "Datasource.host": "localhost2",
            "Datasource.password": "blahblah"
        }
    },
    {
        "if": {
            "class": "shp"
        },
        "then": {
            "Datasource.file": "/data/{id}.shp"
        }
    }
]

You can also have multiple conditions (which are ANDed):

[
    {
        "if": {
            "geometry": "multipolygon",
            "class": "bigdata"
        },
        "then": {
            "Datasource.dbname": "anotherdb",
            "Datasource.host": "hostforbigqueries",
            "Datasource.password": "123456"
        }
    }
]

You can also test on an array of values (which are ORed):

[
    {
        "if": {
            "id": ["id1", "id2"]
        },
        "then": {
            "Datasource.dbname": "anotherdb",
            "Datasource.host": "anotherhost",
            "Datasource.password": "123456"
        }
    }
]

You can use dynamic properties of the layer in the final value (this will use Layer.id in the final path):

[
    {
        "if": {
            "class": "shp"
        },
        "then": {
            "Datasource.file": "/data/{id}/{id}.shp"
        }
    }
]

Notes:

  • Fields are relative to Layer. You can use a path as field reference. For example, Datasource.type will look for the field type of Layer.Datasource.
  • only first matching rule apply

Then run the script from command line to get the customized .mml file:

node cartocc.js <path-to-project.mml> <path-to-custom-rules.json> > local_project.mml
