tv4 File Loader

Adds loading schemas from a single file or a directory functionality to the tv4 schema validator.

npm version Build Status Dependencies Dev Dependencies codecov.io

Overview

Simplifies the process of adding all schemas from a folder or a single file by attaching the loadSchemaFileAsync() and loadSchemaFolderAsync functions to tv4.

Installation

Use npm to install this package easily.

$ npm install --save tv4-file-loader

Alternately you may edit your package.json and add this to your dependencies object:

{
    ...
    "dependencies": {
        ...
        "tv4-file-loader": "*"
        ...
    }
    ...
}

Functions attached to tv4

promise = loadSchemaFileAsync(schemaPath, relativeTo)

Loads a schema from a file. Returns an empty promise when it has finished loading the schema.

  • schemaPath is the path to the desired schema on the filesystem.
  • relativeTo this property is used to create the schema name. For example if your schema was in my-schemas/hello.json but you wanted to reference it as hello.json you could pass relativeTo as my-schemas`.

promise = loadSchemaFolderAsync(startPath)

Loads a directory of schemas. Returns an empty promise when it has finished loading the schemas in the folder.

  • startPath is the folder containing the schemas that will be loaded.

Usage

First, require tv4.

var tv4;

tv4 = require("tv4");

Then, require the tv4-file-loader module and pass the newly created tv4 into it. The tv4-file-loader factory returns the tv4 instance for convenience.

tv4 = require("tv4-file-loader")(tv4);

Voila! Now you have the loadSchemaFileAsync() and loadSchemaFolderAsync() functions available to you through tv4. You can use them like so:

tv4.loadSchemaFileAsync(`${__dirname}/schemas/example-schema.json`, ".");
tv4.loadSchemaFolderAsync(`${__dirname}/anotherSchemaFolder/`);

Since both function return promises, they are able to be .then()ed.

tv.loadSchemaFolderAsync("./testSchemaFolder/").then(() => {
    console.log("Yay, our schemas from ./testSchemaFolder/ have been loaded!");
});
