0.1.13 • Public • Published


    A simple way to store app settings and configs. I thought this would be a quick find on nodejs, but everything was too basic, or too complicated... nothing in that "goldylocks" zone.

    Works in Node (stores to a simple text file as JSON) and in browsers (store to localStorage).


    • No complicated setup
    • No database
    • No dependencies
    • Easy set / get
    • Data stored as JSON.
    • Automatically stores in CWD (current working directory) (Node) or to localStorage (browser)
    • Manually modify store files (Node)
    • Pre-populate store files (Node)
    • Use "dot" notation to set/get objects/arrays -- or operate directly on the data object.
    • Use in browser (for browsers that support localStorage)

    Get it

    npm install storeset --save

    Use it

    // 30 second setup.
    var store = require("storeset");
    // Works "out of the box" without any setup --
    // data automatically saved to "store.json" in the CWD.
    // Setting values
    store.set("sunny", true);
    // Use dot notation for multi-dimensional objects and arrays
    store.set("sally.sees", ["bob", "tom"]);
    // Getting values:
    var sunny = store.get("sunny"); // Returns TRUE
    var sees0 = store.get("sally.sees.0"); // Returns the first index of the array.
    // Operate directly on the storage object
    var storeData = store.getDataObject();
    storeData.bob = "hello";
    // Access either way:
    var seeBob = store.get("bob"); 	// "hello" - These two are identical
    var seeBob = storeData.bob; 	// "hello" - These two are identical; // save it to disk (or localStorage for browser).

    Create (optional)

    By default data is store in the CWD (current working directory) via:

    var dataFilePath = path.resolve(process.cwd(), dataFileName);

    Specify a different location for the store file and JSON formatting manually.

    store.create(file [, format]);


        file    :   A filename or path to file. If using just a filename,
                    we'll automatically put it into CWD (current working directory).
                    Again, this create function is optional.
        format  :   [optiona] JSON formatting. Used for the JSON.stringify's "space" argument.
                    The default is "\t" to make the resulting JSOn human-readable.
                    You can use a number, such as 4 to use 4 spaces Or set to null
                    to remove formatting for a smaller store file size.


    store.create(path.resolve(__dirname, dataFileName))

    • You must call create() prior to calling get/set.
    • Use setFormat to configure the format independent of create.
    • There are a few configurable option variables within the storeset.js source file that you can adjust as well. Simply open the storeset.js file (located in the node_modules folder) and see the "Configuration" section.
    • Only one "store" can exist at one time. Calling store.create() multiple times will screw things up. Instead, just set to different keys. e.g. store.set("part1", data1), store.set("part2", data2);
    store.create("store.json", null); // Produces non-formatted store file
    store.create("store.json", 4);    // Formats human readable store file using 4 spaces
    store.create("store.json");       // Defaults human readable store file using tabs
    store.create();                   // Sets everything up using defauls.
                                      //    May make the first "set" faster as it will
                                      //    do preliminary setup
    store.create(null, 4);            // Does a defualt set up, and sets the format option.
    store.create("/system/path/to/store.json") // speifies the store file location

    Setting values

    For simple items, just use simple name / value. For objects and arrays, use the classic "dot" notation that you're familiar with -- the only difference is that it'll be a string.

    store.set(name, value);
        name        : (string) The name or to store the information.
        value       : (mixed) Anything that JSON can store.
    store.set("sunny", false);
    store.set("bob", {age:28, size:"large", glasses:true});
    store.set("sally.sees", ["bob", "tom"]);
    store.set("", 34);
    store.set("", 42);

    Getting values

    Pretty straight forward, behaves like any other varible or object, including "undefined" if not present.

    store.get([name, defaultValue])
       name            :   (optional) The name or to the data you want
       defaultValue    :   (optional) If the value doesn't exist, you can provide a
                            default value to set. This is a shortcut for populating
                            a location with a value if it doesn't exist.
    Examples (based on our "set" examples above):
    var bob = store.get("bob"); // Returns object
    var sally = store.get("sally"); // Returns object {sees : ["bob", "tom"] }
    var sees = store.get("sally.sees"); // Returns array ["bob", "tom"]
    var sees0 = store.get("sally.sees.0"); // Returns array "bob"
    var something = store.get(""); // Returns 34
    var all = store.get() // When no args, the entire store is returned.
    // The following:
    var val = store.get("path", "something");
    // ... is a shortcut for:
    var val = store.get("path");
    if( typeof val != "undefined" ){
        // set() returns what you've just set.
        val = store.set("path", "something");

    Getting all data

    Ways to get all the data:

    1. As a javascript object. Use the standard "get" without any arguments returns a javascript object.
        var storeData = store.get(); // returns a javascript object
    1. As a JSON string
        format  : (optional) mixed. See also "setFormat()" and "JSON Formatting"
                undefined   :   e.g. not set, returns the default, same as TRUE.
                TRUE        :   Formatted according to the formatting established.
                FALSE | null:   Collapse and remove formatting.
                String      :   Apply specific formatting (e.g. "\t")
                Number      :   Number of spaces to use for indent (e.g. 2)
    var storeData = store.getJSON(); // Returns JSON string using default formatting.
    var storeData = store.getJSON(true); // Returns JSON string using default formatting.
    var storeData = store.getJSON(false); // Returns minified JSON string (no formatting).
    var storeData = store.getJSON(null); // Returns minified JSON string (no formatting).
    var storeData = store.getJSON("\t"); // Returns JSON string using tabs for indents.
    var storeData = store.getJSON(4); // Returns JSON string using 4 spaces for indents.


    Resetting and clearing the store will wipe all the data from the store



    By default, the data is always saved when calling "set()".

    If the variable "saveOnSet" within storeset.js is set to FALSE, automatic save will NOT happen after each set() call, which may minimize overhead for each "set" operation.

    However you'll have to call save() manually in your app to store the data using:;

    There is also an additional configuration variable named "saveOnExit", which will save changes when the app closes. Note: saveOnExit is set to FALSE by default. To enable it you'll ahve to manually modify the storeset.js file.

    JSON Formatting

    The store data can be human readable (or not). NOTE: You may also set this up during creation, or modify the default options wihtin this file.

            format : A tab or number. Same as javascript JSON.stringify's "space" argument.
                    - Using a "\t" will make the JSON human readable and indent with tabs.
                    - Using a number will set the number of spaces for each indent level.
                    - Using null (or undefined) will eliminate any formatting, thereby compacting the JSON data.
    store.setFormat("\t")   // Humanize with tab indents
    store.setFormat(2)      // Humanize where each indent is 2 spaces
    store.setFormat()       // Un-humanize and compact JSON
