Node.js parse non-standard hast data to HTML?

How can we convert non-standard hast (which is parsed from a Markdown file) to HTML?
For example, this is the HTML tree data I have:
{
"_path": "/hello",
"_draft": false,
"_partial": false,
"_empty": false,
"title": "Hello!",
"description": "",
"body": {
"type": "root",
"children": [
{
"type": "element",
"tag": "h1",
"props": {
"id": "hello!"
},
"children": [
{
"type": "text",
"value": "Hello!"
}
]
}
],
"toc": {
"title": "",
"searchDepth": 2,
"depth": 2,
"links": []
}
},
"_type": "markdown",
"_id": "content:hello.md",
"_source": "content",
"_file": "hello.md",
"_extension": "md"
}
How can I parse that 'body' bit to HTML in Node.js?
I tried to use hast-util-to-html:
import { toHtml } from 'hast-util-to-html'
console.log('data.body =', toHtml(data.body))
But I got the following error:
TypeError: Cannot read properties of undefined (reading 'toLowerCase')
I think the tag key in the data should be tagName for using hast-util-to-html. tag and prop are non-standard keys I suppose, how can I standardise them?

Passing a parameter between multiple intents triggering Dialogflow's Fulfillment

I have a Dialogflow agent that I've setup with a web hook that is pulling info from a Firebase database. I am trying to have different intents kick off different queries on the DB. From the Welcome Intent the agent asks for a name that it will matching the DB (e.g. Hi it's nice to meet you? What is the name you looking for?). From there the user is gives a name which is a response that triggers another intent called "name." This intent has a parameter called "agent.parameters.defaultName" which is passed into the fulfillment and used to query the DB. Below is the webhook kicks off the following script:
});
process.env.DEBUG = 'dialogflow:debug'; // enables lib debugging statements
exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request,
response) => {
const agent = new WebhookClient({ request, response });
console.log('Dialogflow Request headers: ' +
JSON.stringify(request.headers));
console.log('Dialogflow Request body: ' + JSON.stringify(request.body));
//function to request bio info on the db
function handleData(agent) {
const congressName = agent.parameters.congressName;
return admin.database().ref().once("value").then((snapshot) => {
var nameInfo = snapshot.child('Name/' + congressName + '/profile').val();
agent.add(nameInfo + "\n \n Tell me the first and last name of the next
person you'd like to learn about. Or you can say Twitter to get this
individual's Twitter info.");
});
}
//Function to return the name's tweet info
function handleTweet(agent) {
const congressName = agent.parameters.congressName;
return admin.database().ref().once("value").then((snapshot) => {
var nameTweet = snapshot.child('Name/' + congressName + '/twitter_handle').val();
agent.add(nameTweet);
});
}
// Run the proper function handler based on the matched Dialogflow intent
name
let intentMap = new Map();
intentMap.set('name', handleData);
intentMap.set('name - custom', handleTweet);
agent.handleRequest(intentMap);
});
This returns the bio and prompts the user to say another name or say twitter to pull the twitter info.
If the user says Twitter I'd like for another intent to be triggered. This Intent would also have a fulfillment that would call the DB, but this time it'd pull the Twitter info. Where I'm having an issue is I can't get this intent to trigger the fulfillment. I'm wondering if my parameter is in the right section or if I need to figure out how to pass it to the Twitter intent. I'm not sure where I'm off.
Below are the intents:

Extract information from json

So I have the following object from my controller, which has a name, a list of beans and a list of operations:
{
"name": "Charge",
"beans": [
],
"operations": [
{
"name": "getSize",
"returnType": "java.lang.Integer",
"description": "empty description",
"parameters": [
]
},
{
"name": "truncate",
"returnType": "java.lang.Void",
"description": "empty description",
"parameters": [
]
},
{
"name": "count",
"returnType": "java.lang.Integer",
"description": "empty description",
"parameters": [
{
"name": "javaCode",
"type": "java.lang.String",
"value": null
}
]
},
{
"name": "update",
"returnType": "java.lang.Integer",
"description": "empty description",
"parameters": [
{
"name": "javaSelectCode",
"type": "java.lang.String",
"value": null
},
{
"name": "javaUpdateCode",
"type": "java.lang.String",
"value": null
}
]
},
{
"name": "delete",
"returnType": "java.lang.Integer",
"description": "empty description",
"parameters": [
{
"name": "javaCode",
"type": "java.lang.String",
"value": null
}
]
},
{
"name": "dump",
"returnType": "java.lang.Void",
"description": "empty description",
"parameters": [
{
"name": "javaSelectCode",
"type": "java.lang.String",
"value": null
},
{
"name": "destinationPath",
"type": "java.lang.String",
"value": null
}
]
},
{
"name": "select",
"returnType": "java.lang.String",
"description": "empty description",
"parameters": [
{
"name": "javaCode",
"type": "java.lang.String",
"value": null
}
]
}
],
"$$hashKey": "object:620"
}
Basically I want to display all the operations from this object in a dropdown menu.
So I was thinking of having something like:
<div ng-repeat="operation in object.operations">
{{operation.name}}
</div>
Except the code above doesn't display anything on the screen, no errors in the console, nothing.
Any help would be much appreciated!
EDIT:
Javascript service:
app.controller('selectAll', ['$http', '$scope' , '$rootScope', function ($http, $scope, $rootScope) {
$scope.response;
$scope.operations;
$rootScope.$on("invokeSelectAll", function(){
$scope.invokeSelectAll();
});
$scope.invokeSelectAll = function(){
$scope.response = $http.post('/invoke/selectAll/', $rootScope.dataObj);
$scope.object = JSON.stringify($rootScope.object);
console.log(" object operation from selectAll " + $scope.object);
$scope.response.then(function(data) {
$scope.responses = data.data ? data.data : "Select Operation not supported on this bean";
});
}
}]);

Use JSON.stringify() to create a JSON string from a JavaScript object.
Use JSON.parse() to parse a JSON string to a JavaScript object.
In your case, you need to use JSON.parse() because you get a JSON string from the server and want to parse it to a JavaScript object.
$scope.object = JSON.parse($rootScope.object);

you are using JSON.stringify which is used to change javascript object to string and store it as a string only.
You should Parse the data with JSON.parse(), and the data becomes a JavaScript object. and you can easily use that in ng-repeat.
Try it ,It will work fine

How do I expand nested relationships in REST API using Sails.js

I am a newbie to NodeJS and Sails.js.
I want create a REST API that allows me to expand a resource based on query parameter. For eg
HTTP GET /snippets
{
"count": 1,
"next": null,
"previous": null,
"results": [
{
"url": "http://localhost:8000/snippets/1/",
"highlight": "htep://localhost:8000/snippets/1/highlight/",
"title": "test",
"code": "def test():\r\n pass",
"linenos": false,
"language": "Clipper",
"style": "autumn",
"owner": "http://localhost:8000/users/2/",
"extra": "http://localhost:8000/snippetextras/1/"
}
]}
HTTP GET /snippets?expand=owner
{
"count": 1,
"next": null,
"previous": null,
"results": [
{
"url": "http://localhost:8000/snippets/1/",
"highlight": "http://localhost:8000/snippets/1/highlight/",
"title": "test",
"code": "def test():\r\n pass",
"linenos": false,
"language": "Clipper",
"style": "autumn",
"owner": {
"url": "http://localhost:8000/users/2/",
"username": "test",
"email": "test#test.com"
},
"extra": "http://localhost:8000/snippetextras/1/"
}
]}
Wondering how can I do that in Sails.js or NodeJS?

You should use assocations.
Here is how you would create a one-to-many association between your User model and your Snippet model:
// User.js
module.exports = {
// ...
attributes: {
// ...
snippets: {
collection: 'Snippet',
via: 'owner'
}
}
};
// Snippet.js
module.exports = {
// ...
attributes: {
// ...
owner: {
model: 'User'
}
}
};
Then you can hit /snippets if you want a list of snippets, and hit /snippets?populate=[owner] if you need details about the owners of the snippets.

Iterate through nested Javascript Objects from API response

I've tried 100 different things, and spend days looking through Google and Stackoverflow, but I can't find a solution to this problem. Everything I call after the body of this API response returns undefined!
The response from Facebook SDK looks like this:
[
{
"body": "[
"data": [
{
"name": "Larry Syid Wright",
"administrator": false,
"id": "xxx"
}, {
"name": "Melissa Long Jackson",
"administrator": false,
"id": "xxx"
}, {
"name": "Charlotte Masson",
"administrator": false,
"id": "xxx"
}
],
"paging": {
"next": "url"
}
]"
},{
"body": "{
"data": [
{
"id": "xxx_xxx",
"message": "In honor of Halloween, how many of you have your own ghost stories? Who believes in ghosts and who doesn't?",
"type": "status",
"created_time": "2014-10-31T20:02:01+0000",
"updated_time": "2014-11-01T02:52:51+0000",
"likes": {

}
}
}
},{

"name": "Jessica Starling"
},

"updated_time": "2014-11-01T02:36:21+0000",
"likes": {
"data": [
{
"id": "xxx",
"name": "Scott Williams"n
}
]
}
}
],
"paging": {
"previous": "xxx",
"next": "xxx"
}
}"
}
]
This response is from a batch call. If I call them separately, I can easily iterate through the responses, and get everything from them. When I call them in the batch though, I can't get past "body", and I need to use a batch call.
console.log(response[0].body); will return the object inside the body of the first part of the response, but console.log(response[0].body.data); returns undefined. I just don't get it. This should be simple but it's like there's a lock on the door and I don't have the right key.
I normally have no issue iterating through objects, so I don't need a generalized answer. I need help seeing whatever it is here that I don't see. Why does the console show undefined when I call anything after the body, and what do I need to be doing to get any of these values?

That JSON contains nested JSON. body seems to be a string. Use
var body = JSON.parse(response[0].body);

The values from the body are just strings.which are embedded as json.So firstly you would need to parse them using JSON.parse.
The code would be like
var body = JSON.parse(response[0].body);
