How can I get all the name parts of all the second choices in a json object

This is the full object that I want to get something from is:
{
"name": "permissions",
"description": "Get or edit permissions for a user or a role",
"options": [
{
"name": "user",
"description": "Get or edit permissions for a user",
"type": 2,
"options": [
{
"name": "get",
"description": "Get permissions for a user",
"type": 1,
"options": [
{
"name": "user",
"description": "The user to get",
"type": 6,
"required": true
},
{
"name": "channel",
"description": "The channel permissions to get. If omitted, the guild permissions will be returned",
"type": 7,
"required": false
}
]
},
{
"name": "edit",
"description": "Edit permissions for a user",
"type": 1,
"options": [
{
"name": "user",
"description": "The user to edit",
"type": 6,
"required": true
},
{
"name": "channel",
"description": "The channel permissions to edit. If omitted, the guild permissions will be edited",
"type": 7,
"required": false
}
]
}
]
},
{
"name": "role",
"description": "Get or edit permissions for a role",
"type": 2,
"options": [
{
"name": "get",
"description": "Get permissions for a role",
"type": 1,
"options": [
{
"name": "role",
"description": "The role to get",
"type": 8,
"required": true
},
{
"name": "channel",
"description": "The channel permissions to get. If omitted, the guild permissions will be returned",
"type": 7,
"required": false
}
]
},
{
"name": "edit",
"description": "Edit permissions for a role",
"type": 1,
"options": [
{
"name": "role",
"description": "The role to edit",
"type": 8,
"required": true
},
{
"name": "channel",
"description": "The channel permissions to edit. If omitted, the guild permissions will be edited",
"type": 7,
"required": false
}
]
}
]
}
]
}
I want to get all of these name attributes from the first json object and assign them all to different variables in javascript? How can I achieve this?
Permissions ---> role ---> edit ---> channel (In other words I want to get all of the name parts in all the second choices in the json object)

If you know that JSON structure is fixed then it will be easy.
Consider your json is assigned to permissionJson then you can write it as
permissionJson.name // permissions
permissionJson.options[1].name. // role
permissionJson.options[1].options[1].name // edit
permissionJson.options[1].options[1].options[1].name // channel
if JSON structure is dynamic then you might need loops to extract the options array index 1 element at each level and find its name.

first of all i want to make clear that i don't understand your question very well. So correct me if i misunderstood something.
you said you want to get all name parts in all second member of options(root one) array. so all you have to do is
JSON_DATA.options[1]
Here you have selected whole role object. to get more deeper you can use dot operator. For instance Permissions ---> role ---> edit ---> channel. this could be accessed by this line JSON_DATA.options[1].options[1]
it will return this
{
"name": "channel",
"description": "The channel permissions to get. If omitted, the guild permissions will be returned",
"type": 7,
"required": false
}

This solution works generic for as deep as the object might get in the future
This is the solution for you: Just use this function, and create the variable allSecondNames:
const allSecondNames = [];
func = a => {
if (a.name) allSecondNames.push(a.name);
if (a.options) func(a.options)
if (a[1] && a[1].name) allSecondNames.push(a[1].name);
if (a[1]?.options) func(a[1].options)
}
Sending your JSON to function func would put in variable allSecondNames:
["permissions", "role", "edit", "channel"]

How can I access all the "text" properties of the json of cucumber's "step"-object and log them to the console?

I'm trying to log the string/regex of a step description of a cucumber 'step'-oject to the console. This is an example step
Given Alice is hungry
... and this is the first line to the step definition
Given( /^Alice is hungry$/, () => {
I'm trying to log 'Given Alice is hungry' to console, using the string representation of a 'step'-object that's provided as an argument, in the context of a cucumber-specific hook of webdriverio. Running
beforeStep: function ({ uri, feature, step }, context) {
console.log(`Running "${JSON.stringify(step, null, 4)}"`);
}
...produces this output:
[0-0] Running "{
"uri": "featureFiles\\dev\\my-first-feature-file.feature",
"feature": {
"type": "Feature",
"tags": [],
"location": {
"line": 8,
"column": 1
},
"language": "en",
"keyword": "Functionality",
"name": "Eating too many cucumbers is not good for you",
"children": [
{
"type": "Scenario",
"tags": [

"type": "Tag",
"location": {
"line": 10,
"column": 3
},

}
],
"location": {
"line": 11,
"column": 3
},
"keyword": "Szenario",
"name": "Eating a few is no problem",
"steps": [
{
"type": "Hook",
"location": {

},
"keyword": "Hook",
"text": ""
},
{
"type": "Step",
"location": {
"line": 12,
"column": 3
},
"keyword": "Given",
"text": "Alice is hungry"
},
{
"type": "Step",
"location": {
"line": 13,
"column": 5
},
"keyword": "When ",
"text": "she eats 3 cucumbers'"
},
{
"type": "Step",
"location": {
"line": 14,
"column": 5
},
"keyword": "Then ",
"text": "she will be full"
},
However, when I use
beforeStep: function ({ uri, feature, step }, context) {
// eslint-disable-next-line no-undef
console.log(\`Running step "${step.text}"`);
}
...all i get is
[0-0] Running "undefined"
[0-0] Running "undefined"
I've tried these 2 options instead:
console.log(`Running "${step.feature.children.steps.text}"`);
console.log(`Running "${feature.children.steps.text}"`);
In both cases this produces the following result:
[0-0] Error in "BeforeStep Hook"
Cannot read property 'text' of undefined
What am I doing wrong?

Let's take this example:
${step.feature.children.steps.text}
children is an array, so you can't just type .steps. You need to access a certain element first, like [0].steps.
Similarly with steps, steps is an array:
"steps": [ ... ]
This ${step.text} doesn't work because step doesn't have a property text. It has the following keys:
uri
feature

I accepted pavelsman answer as the problem's solution.
For anyone who wants to log the cucumber steps to the console right when they're executing, just add this to the wdio-configuration file:
let scenarioIndex = 0;
let stepIndex = 0;
beforeStep: function ({uri, feature, step}, context) {
if(typeof step.feature.children[scenarioIndex] !== "undefined") {
let keyword = step.feature.children[scenarioIndex].steps[stepIndex].keyword;
let stepText = step.feature.children[scenarioIndex].steps[stepIndex].text;
if (stepText !== "") {
console.log(keyword + stepText);
}
stepIndex++;
}
},
afterScenario: function () {
scenarioIndex++;
stepIndex = 0;
},

Generate an output JSON message from an input JSON message based on an output JSON schema

I have a requirement to write a NodeJS solution and library to receive an input JSON data which the solution must transform into an output JSON data that matches or validates to a provided output JSON schema.
At the moment, I have an input file that validates to the destination JSON schema but has some missing fields and default values that the business rules permit as part of the transformation.
The source JSON is as follows:
{
"messageContext" : {
"statement" : "mediaDelivered",
"services" :[
"mss"
],
"domain":"my.xxx.yyy.create",
"function":"FCG"
},
"header" : {

},
"data" :{
"operation": "CREATE",
"payload": {
"s3": "https://wildwildwest.amazonaws.com/png/myimg.mov"

I have been digging about and would like to know your thoughts on the best approach and Node libraries for solving this problem in NodeJS Javascript.

I found the Joi library to be a direct fit for my use case. I have tested and used it and it worked for me and gave me the need control to enforce the schema's constraints.
https://www.npmjs.com/package/joi
Another library the might be useful is https://www.npmjs.com/package/is-my-json-valid. However, I have not tested this library in depth.

trouble while parsing json

I am trying to react displayName in req
when I write
console.log(req.session.passport.user._raw)
the output is:
{
"kind": "plus#person",
"etag": "\"ucaTEV-ZanNH5M3SCxYRM0QRw2Y/XiR7kPThRbzcIw-YLiARoF22TMY\"",
"emails": [
{
"value": "rajanlagah#gmail.com",
"type": "account"
}
],
"objectType": "person",
"id": "100428644453494579140",
"displayName": "Rajan Lagah",
"name": {
"familyName": "Lagah",
"givenName": "Rajan"
},
"url": "https://plus.google.com/100428644453494579140",
"image": {
"url": "https://lh3.googleusercontent.com/-XdUIqdMkCWA/AAAAAAAAAAI/AAAAAAAAAAA/4252rscbv5M/photo.jpg?sz=50",
"isDefault": true
},
"isPlusUser": true,
"language": "en",
"circledByCount": 0,
"verified": false
}
Now the from this object I am trying to get kind (say)
console.log(req.session.passport.user._raw.kind)
then the output is undefined
Can any one tell my mistake?

Is req.session.passport.user._raw a string? You may need to parse it first, eg:
var data = JSON.parse(req.session.passport.user._raw);
console.log(data.kind);

TypeError: Object [object Array] has no method 'getProperty'

I'm kind of new to this whole posting a question thing, so please be gentle!
I am using Breeze as part of the "Hot Towel" SPA stack and retrieving data from a custom WebApi endpoint written in PHP. It's not a full implementation, I've just written enough to give me what I need.
The metadata my endpoint is generating is as follows:
{
"shortName": "Project",
"namespace": "WebApi.ORM.Cartesius",
"autoGeneratedKeyType": "Identity",
"defaultResourceName": "Project",
"dataProperties": [
{
"name": "id",
"isPartOfKey": true,
"isNullable": false,
"dataType": "Int32"
},
{
"name": "title",
"isNullable": false,
"maxLength": 256,
"dataType": "String"
},
{
"name": "date",
"isNullable": false,
"dataType": "DateTime"
},
{
"name": "review_date",
"isNullable": true,
"dataType": "DateTime"
},
{
"name": "summary",
"isNullable": true,
"dataType": "String"
}
],
"navigationProperties": [
{
"name": "Team",
"entityTypeName": "Team:#WebApi.ORM.Cartesius",
"isScalar": true,
"associationName": "team_project_id_fkey",
"invForeignKeyNames": [
"project_id"
]
},
{
"name": "ProjectAuthor",
"entityTypeName": "ProjectAuthor:#WebApi.ORM.Cartesius",
"isScalar": true,
"associationName": "project_author_project_id_fkey",
"invForeignKeyNames": [
"project_id"
]
},
{
"name": "Itinerary",
"entityTypeName": "Itinerary:#WebApi.ORM.Cartesius",
"isScalar": true,
"associationName": "itinerary_project_id_fkey",
"invForeignKeyNames": [
"project_id"
]
},
Everything is working fine until I try and do an expand on my query:
var query = new breeze.EntityQuery()
.from("Project")
.where("id","eq",project.id)
.expand("ProjectAuthor");
This query returns the following from my endpoint:
[
{
"$id": 1,
"$type": "WebApi.ORM.Cartesius.Project",
"id": 2,
"title": "teat",
"date": "2013-11-04 14:00:00+07",
"review_date": null,
"summary": null,
"ProjectAuthor": [
{
"$id": 2,
"$type": "WebApi.ORM.Cartesius.ProjectAuthor",
"id": 1,
"account_id": 1,
"project_id": 2,
"Project": [
{
"$ref": 1
}
]
},
{
"$id": 3,
"$type": "WebApi.ORM.Cartesius.ProjectAuthor",
"id": 3,
"account_id": 2,
"project_id": 2,
"Project": [
{
"$ref": 1
}
]
}
]
}
]
Then Breeze chokes on it throwing:
TypeError: Object [object Array] has no method 'getProperty'
Debugging points to line 5059 in Breeze where it tries to getProperty on an array of entities rather than a single entity I assumed this had something to do with whether the navigation property was set to scalar or not but switching them around made no difference.
I'm sure I'm doing something massively wrong, but I can't figure out what it is and I've kind of hit a brick wall. I've read the docs from top to bottom and am implementing this as best as I can understand but it's possible I'm a little confused.
Thanks in advance for any help and apologies if I have not made myself clear or provided enough info

I think your problem is in the metadata
"name": "ProjectAuthor",
"entityTypeName": "ProjectAuthor:#WebApi.ORM.Cartesius",
"isScalar": true,
"associationName": "project_author_project_id_fkey",
"invForeignKeyNames": [
"project_id"
]
},
On that nav property Project->ProjectAuthor your telling it that its a scalar but its not in the data set..
"ProjectAuthor": [
{
..........
I've had this problem aswell .. 99% time its a metadata problem, if not there then start cutting metadata apart until you isolate the error .. though I'm sure thats the problem.. you need a hasMany there and an isScalar on the inverse navigation
