Given a template string like "/posts/{postId}.json", query the replica for docs with matching paths.

See the docs for matchTemplateAndPath for details on template strings.

You can get the variables out of your document paths like this:

 let template = '/posts/{postId}.json';
 let docs = await queryByTemplate(myReplica, template);
 for (let doc of docs) {
     // vars will be like { postId: 'abc' }
     let vars = extractTemplateVariablesFromPath(template, doc.path);
 }
