tailwindcss-mongodb v0.0.5

Tailwindcss Mongodb

Retreive css classes from the database and add them to safelist so that tailwind can detect those classes.

Basic Usage

Add the plugin and the path to the safelist file in tailwind.config.js

module.exports = {
    content: [
        ".safelist"
    ],
    plugins: [
        require("tailwindcss-mongodb")({
            callback: async (client) => {
                // return an array of strings (classnames)
                return [
                "md-1", "text-white/70" //...
                ];
            }, 
            // Path to save the safelist file, the same must be added in the content so that tailwind can parse the file
            path: ".safelist",
            // Mongodb connection string
            uri: "mongodb+srv://<username>:<password>@<your-cluster-url>/test?retryWrites=true&w=majority",
            debug: false
        })
    ]
};

Basic usage

Sample Callback function:

async (client) => {
    // Select database `test`
    const db = client.db("test");
    // Select collection `page`
    const collection = db.collection("page");

    // Get all records
    const findResult = await collection.find({}).toArray();

    // Flatten the JSON  `findResult
    // flat library is required
    // const flatten = require("flat")
    const arr = flatten(findResult);

    // Find all values where key includes class and split the value by space
    let classes = [];
    Object.keys(arr)
        .filter((key) => key.includes("class"))
        .map((key) => arr[key])
        .map((item) => {
            if (item.trim() != "") {
                classes = classes.concat(item.trim().split(" "));
            }
        });
    // Ensure classes are unique
    return classes.filter((cls, index, cls_array) => cls_array.indexOf(cls) === index);
}

Full Example

const flatten = require("flat")

module.exports = {
    content: [
        ".safelist",
    ],
    plugins: [
        require("tailwindcss-mongodb")({
            callback: async (client) => {
                const db = client.db("test");
                const collection = db.collection("page");
                const findResult = await collection.find({}).toArray();
                const arr = flatten(findResult);
                let classes = [];
                Object.keys(arr)
                    .filter((key) => key.includes("class"))
                    .map((key) => arr[key])
                    .map((item) => {
                        if (item.trim() != "") {
                            classes = classes.concat(item.trim().split(" "));
                        }
                    });
                return classes.filter((cls, index, cls_array) => cls_array.indexOf(cls) === index);
            }, 
            path: ".safelist",
            uri: "mongodb://localhost:27017",
        })
    ]
