ql.io-uri-template v0.8.0

This module provides a small URI template parser. ql.io uses URI templates for specifying URIs of APIs. See docs for more examples.

Syntax Overview

Here is overview of the syntax.

1. Each template can have an arbitrary number of tokens enclosed in braces ({ and }).

   http://myserver/somepath?p1={v1}&p2={v2}

2. You can generate URIs from URI templates by calling the format() function with an object containing values, and optionally, default values.

3. All tokens are optional and single valued by default.

4. You can mark that a token is required by prefixing the name of the token with ^. When the value for a required token is missing, formatting will fail.

   http://myserver/somepath?p1={^v1}&p2={v2}

5. You can also mark that a token is multi-valued by prefixing the name of the token with a |.

   http://myserver/somepath?p2={|v2}

If the value of v2 is ['v2_1','v2_2'], calling the format() would result in

http://myserver/somepath?p2=v2_1,v2_2

Some APIs may not take more than a given number of values. In such cases, you can specify a maximum integer before |.

http://myserver/somepath?p1={^v1}&p2={5|v2}

If you supply more than 5 values, the format() function will return Math.ceil(n/5) URIs.
