The renderUser function is a Node.js module that retrieves and renders templates from Google Sheets for a given user, incorporating user-specific data and links. The function, which returns a promise, is part of a larger application that utilizes Google Sheets as a data source for templates.

Run example

npm run import -- "create a study sauce user directory"

create a study sauce user directory

var uuid = require('uuid/v1');
var {Readable} = require('stream');
var importer = require('../Core');
var getTemplates = importer.import("templates google sheet");
var wrapTemplate = importer.import("output google sheet template");
var getTemplateProperties = importer.import("google sheet template properties");
var collectTemplateResources = importer.import("collect google sheet resources");


// TODO: make this generic for use with user related packs and state changes?
function renderUser(user) {
    var properties = {}, templates;
    
    return getTemplates(process.env.DOCID)
        .then(t => {
            templates = t;
            return getTemplateProperties('app', properties, templates);
        })
        .then(() => getTemplateProperties('user', properties, templates))
        .then(() => {
            var users = properties['user-data'];
            Object.assign(properties, {
                'base': user + '/',
                'users-users-link': `/${user}/users`
            })
            templates['users-users'] = {template: {rows: [[`{{> users/users-users-link}}`]]}}
        })
        .then(() => getTemplateProperties('users-users', properties, templates))
        .then(() => wrapTemplate(`${user}/users`, 'users', properties['users-users'], properties))
        .then(page => collectTemplateResources(
            `${user}/users`,
            page,
            properties,
            templates,
            process.env.BUCKET))
        .then(resources => (console.log(resources), `/${user}/users`))
}

module.exports = renderUser;

  });

  // Collect template properties for 'users-users' page.
  await getTemplateProperties('users-users', properties, templates);

  // Wrap the template and collect resources.

Code Breakdown

This code is written in JavaScript and utilizes the Node.js ecosystem. It appears to be a part of a larger application that utilizes Google Sheets as a data source for templates.

Dependencies and Imports

• uuid/v1 is a library for generating unique IDs.
• stream is a built-in Node.js module for working with streams.
• importer is a custom module that imports other modules from the ../Core directory.
• getTemplates, wrapTemplate, getTemplateProperties, and collectTemplateResources are functions imported from other modules using the importer.

Function: renderUser

renderUser is a function that takes a user object as an argument and returns a promise. The function is responsible for retrieving and rendering templates from Google Sheets for a given user.

Here's a high-level overview of the steps involved:

1. Retrieve templates from Google Sheets based on the DOCID environment variable.
2. Retrieve template properties for the app and user templates.
3. Update the template properties with user-specific data and links.
4. Retrieve template properties for the users-users template.
5. Wrap the users-users template with the updated template properties.
6. Collect resources for the users-users template.
7. Log the collected resources and return the URL of the rendered template.

Export

The renderUser function is exported as a module, making it available for use in other parts of the application.
