falcor-query-syntax

Create Falcor paths from ES6 Template strings with a JSON-like structure.

Usage

Importing the syntax and initializing a Falcor Model:

var falcor = require('@graphistry/falcor');

var model = new falcor.Model({ source: new falcor.HttpDataSource('/model.json') });

Using a Path Map to retrieve data from a Falcor Model:

var range = {length: 2};

var QL = require('@graphistry/falcor-query-syntax');

var results = model.
  get(...QL`{
    genreLists: {
      [0..1]: {
        name,
        titles: {
          [${range}]: {
            name,
            rating,
            boxshot
          },
          length
        }
      },
      length
    }
  }`).
  then(({json}) => console.log(JSON.stringify(json,null,2)));

The code above is equivalent to the following:

var range = {length: 2};

var results = 
  model.
    get(
      ["genreLists", {to:1}, "name"],
      ["genreLists", {to:1}, "titles", range, ["name","rating","boxshot"]],
      ["genreLists", {to:1}, "titles", "length"],
      ["genreLists", "length"]).
    then(({json}) => console.log(JSON.stringify(json,null,2)));
