Gatsby: Re-execute page queries manually

Do you know if it's possible to re-execute Gatsby page queries (normal queries) manually?
Note, This should happen in dev mode while gatsby develop runs.
Background info: I'm trying to set up a draft environment with Gatsby and a Headless CMS (Craft CMS in my case). I want gatsby develop to run on, say, heroku. The CMS requests a Gatsby page, passing a specific draft-token as an URL param, and then the page queries should be re-executed, using the token to re-fetch the draft content from the CMS rather than the published content.
I'm hooking into the token-request via a middleware defined in gatsby-config.js. This is all based on https://gist.github.com/monachilada/af7e92a86e0d27ba47a8597ac4e4b105
I tried
createSchemaCustomization({ refresh: true }).then(() => {
sourceNodes()
})
but this completely re-creates all pages. I really only want the page queries to be extracted/executed.

Probably you are looking for this. Basically, you need to set an environment variable (ENABLE_GATSBY_REFRESH_ENDPOINT) which opens and exposes a /__refresh webhook that is able to receive POST requests to refresh the sourced content. This exposed webhook can be triggered whenever remote data changes, which means you can update your data without re-launching the development server.
You can also trigger it manually using: curl -X POST http://localhost:8000/__refresh
If you need a detailed explanation of how to set .env variables in Gatsby just tell me and I will provide a detailed explanation. But you just need to create a .env file with your variables (ENABLE_GATSBY_REFRESH_ENDPOINT=true) and place this snippet in your gatsby-config.js:
require("dotenv").config({
path: `.env.${activeEnv}`,
})
Of course, it will only work under the development environment but in this case, it fits your requirements.

Rebuild for all is needed f.e. when you have indexing pages.
It looks like you need some logic to conditionally call createPage (with all data refetched) or even conditionally fetch data for selected pages only.
If amount (of pages) is relatively not so big I would fetch for all data to get page update times. Then in loop conditionally (time within a few minutes - no needs to pass parameter) call createPage.
If develop doesn't call 'createPage' on /__refresh ... dive deeper into gatsby code and find logic and way to modify redux touched nodes.
... or search for other optimization techniques you can use for this scenario (queried data cached into json files?).

Does anyone have the ability to create an account with my key?

EDIT : tried the authorized domain and it seems to be what i need, i'll try to go deeper with André's answer :)
Thank you !
Hi,
I'm new to firebase and i just finished a project but i had a question:
Since the doc says i have to put my api keys and else in the javascript, they are visible to anyone even if put into process.env
i've read here : Is it safe to expose Firebase apiKey to the public?
that making the api key public is normal and not a big deal.
I'm using the email/password auth and i'm scared
If someone takes my :
API_KEY_FIREBASE
AUTH_DOMAIN
DB_URL
PROJECT_ID
that are in the source code and use the createAccount function, is he gonna be able to create an account ?
Is yes, is there a way to disable this ?
I want to be able to create account only through the firebase console
I'm not using firebase database for my data, i only use it for auth so i don't have to create a user table in my database, but i use the IDTokens they provide to secure some routes on express.
thank you ! :)

Someone can only create an account when you have that option enabled in your firebase console. So If you have it disabled there is no problem.
You can look here in the "before you begin" section for how to enable/disable Email/password sign-in method.

How can I keep both users tables "synchronized" using BackAnd?

I'm good with registering users, login, etc.
Now I'm getting into modifying users with:
this.backand.object.update('users', user.userId, user)
but I can see that only my table gets modified, while I'll also need to modify the "Registered Users" table existing in "Security & Auth > Registered Users".
I understand I might need to create a custom action...maybe "Before Update"? ...but I can't find documentation on how to modify that specific table (via API or via BackAnd actions).
Thank you.

thanks for using Backand! We don't offer any methods via the SDK to update the registered users. You can use the HTTP object to send a call to the back-end's REST API directly, hitting the same URL that the SDK requests when creating a new user, but this isn't officially documented. In general, we try to limit direct modifications of the registered users table, as there are some security concerns regarding how frequently the data is accessed and modified, but you can access the users object directly via the /users URL. There is an article in our documentation at http://docs.backand.com/en/latest/apidocs/security/index.html#link-your-app-39-s-users-with-backand-39-s-registered-users that covers an automated process for making these kinds of changes - you should be able to adapt some of the server side code in that example to work with your use case.
One alternative that would work now would be to have any change in basic information (username, password, firstname, lastname) result in a new user being created, and you could then use a custom action to perform the migration to the new user, but that is unnecessarily complex. I will add a ticket for our developers to look at adding this registered user management functionality in the future.

how to get account details when integrating plaid api

I am actually trying to integrate Plaid api for ACH payments and following "https://plaid.com/docs/link/" tutorial in Ruby. In this I have written the js code and it shows me pop up to select bank accounts.
I am using it in sandbox mode in which I am using test credentials to verify the account and it successfully verifies the account. For server side scripting I have installed plaid gem and configured it using following code into my_app/config/initializers/plaid.rb
Plaid.config do |p|
p.customer_id = 'test_id'
p.secret = 'test_secret'
p.environment_location = 'https://tartan.plaid.com'
end
where I have replaced the customer_id and secret key with my own. I am using a user controller in which under create method I am trying to create a user like this:
user = Plaid.add_user('auth', 'plaid_test', 'plaid_good', 'usaa', '1234')
Now I am confused how would it work.
I am trying to create a server side handler using ruby but I dont understand where I am lacking (as I am new to Ruby). I actually want that after successfully validating credentials there should be an option to select account like in the given demo
https://demo.plaid.com/stripe
I really need help as I am badly stuck in this from last three days. Any help would be appreciated. Thanks

Plaid Link returns a 'public_token' - you'll need to use the /exchange_token API endpoint to exchange the public token for an API access token.
The plaid-ruby library has a detailed example of the exchange token flow!

Where to place remote hooks (beforeRemote, afterRemote)code in yo loopback generated code

I'm using loopback generator to generate models and rest APIs service. Now I wanted to modify a rest api such that everytime the api is called, some spcific logging/actions are taken.
I've come to know that by using remote hooks(beforeRemote, afterRemote), we can specify actions to be taken for different remote method calls. But what I don't know is that where to place the code of remote hooks. In which file this code will go when the project has been created using 'yo loopback'.

You would add code to the files under /common/models.
If you are using a Person model. You would add the following code in /common/models/person.js:

If you want to protect the REST API from a non logged in user or anonymous user you should use ACL. Have a look here:
Define access control from the intermediate tutorial
Authentication, authorization, and permissions
The REST API will respond with codes if someone unauthorized tries to get access (depending on what you define), for example 401. Then in the app if you receive that code, you should redirect to the login.
Now, every time you create a new model with slc loopback:model, it will generate 2 files in the common/models folder. One is a .js and the ohter a .json. You have to add the code in the .js file for the remote hooks.
Have a look to this link that explains how to add remote methods.
