A tiny language that defines a simple, familiar interface to substitute JSON into strings.
A Javascript implementation of the JSON Template Language as defined in the JSON Template Language Draft.
Specifying interfaces, runtime expression mapping, other forms of programmatically interacting with JSON and URIs.
- specifying interfaces
- easily identify and describe the object and array parts of a template.
- define computed links.
- runtime usage
- a simple and restricted embedded template language.
- interopability between JSON, URIs specifications
- its just JSON -- nothing new to learn.
- familiar Javascript template syntax.
To use the Javascript client you can:
Install it:
npm install @etclabscore/string-json-template-language --save
Import it:
import compileTemplate from "@etclabscore/string-json-template-language";
Use it somewhere:
const parsedJson = JSON.parse('{ "foo": "bar" }');
const template = "${foo}";
const resultString = compileTemplate(parsedJson, template);
// => "bar"
for the given JSON:
{
"query": {
"number": 1,
"salad": "potato"
}
}
and the given template:
http://www.example.com/foo?number=${query.number}&salad=${query.salad}
\__________/ \__________/

| |
For each key in given JSON, substitute it by key into the string.
http://www.example.com/foo?number=1&salad=potato
for the given JSON
{
"query": {
"numbers": [0, 1, 2, 3],
"salads": ["caesar", "potato"]
}
}
and the given template:
http://www.example.com/foo?number=${query.numbers[1]}&salad=${query.salads[1]}
\_____________/ \_____________/

For each key in given JSON, subtitute it by array index into the string.
