+## Template Cheat Sheet
+
+### 1. Global objects injected into every `.erb`
+
+| Variable | Type          | Meaning                                                         |
+| -------- | ------------- | --------------------------------------------------------------- |
+| `@schema` | `Hash`        | Full JSON project skeleton.                                    |
+| `@entities` | `Array<Hash>` | Shortcut for `@schema['entities']`.                           |
+| `@migrations`, `@seeds` | `Array`        | Raw migration / seed arrays.                          |
+| `@project_with_web_site` | `Boolean`     | `true` if the project includes a public web-site.     |
+| `@component_types` | `Array<String>` | Unique list of component types used by the web-site.   |
+
+---
+
+### 2. Extra objects available **when the file/dir name contains `((name))`, `{{Name}}`, etc.**
+
+| Variable     | Type            | Meaning                                                           |
+| ------------ | --------------- | ----------------------------------------------------------------- |
+| `@name`      | `String`        | Current entity name (`snake_case`).                               |
+| `@entity`    | `Hash`          | Full entity record.                                               |
+| `@fields`    | `Array<Hash>`   | Shortcut for `@entity['fields']`.                                 |
+| `@all_fields`| `Array<Hash>`   | All fields from all entities; each field has `field['entity_name']`. |
+
+---
+
+### 3. Single `field` structure
+
+````
+field = {
+  '@name'     => 'firstName',
+  '@name_cap' => 'FirstName',
+  '@type'     => 'string',
+  '@ref'      => 'users',          # present only for relations
+  'title'     => 'First Name',
+  'unique'    => false,
+  # …plus any other keys from the schema
+}
+````
+### 4. Placeholder macros
+
+| Macro                     | Replaced by                  |
+|---------------------------|------------------------------|
+| `((name))` / `{{name}}`   | `users`                      |
+| `((Name))` / `{{Name}}`   | `Users`                      |
+| `((NAME))`                | `USERS`                      |
+| `{{migration-timestamp}}` | *Epoch ms* of the migration  |
+| `{{seed-timestamp}}`      | `YYYYMMDDHHMMSS` of the seed |
+
+*Any path that contains one of these tokens is cloned for **each** entity.*
+
+---
+
+### 6. Worked example
+
+```erb
+form_fields = @fields.select { |f| f['@type'] == 'relation_one' }
+form_fields.each do |f|
+  await ((name)).set<%= f['@name_cap'] %>(data.<%= f['@name'] %> || null, { transaction })
+end
+```
+## More ERB-style snippets
+
+### A. Simple sidebar route list
+
+
+<!-- sidebarRoutes.ts -->
+```erb
+export const routes = [
+<% @entities.each_with_index do |e, i| %>
+  { path: '/<%= e['@name'] %>', label: '<%= e['@name_cap'] %>' }<%= ',' unless i == @entities.size - 1 %>
+<% end %>
+];
+```
+### Sequelize model attributes (primitive fields only)
+```erb
+  attributes: {
+<% @fields.select { |f| %w[string int decimal boolean date datetime enum].include?(f['@type']) }.each do |f| %>
+  <%= f['@name'] %>: {
+    type: DataTypes.<%= get_sequelize_field_type(f['@type']) %>,
+  },
+<% end %>
+},
+```
+
+### TypeScript enums for every enum field in every entity
+```erb
+<!-- enums.ts -->
+<% @entities.each do |e| %>
+    <% e['fields'].select { |f| f['@type'] == 'enum' }.each do |f| %>
+    export enum <%= e['@name_cap'] %><%= f['@name_cap'] %>Enum {
+        <% f['options'].each do |o| %>
+          <%= o.upcase %> = '<%= o %>',
+        <% end %>
+    }
+    <% end %>
+<% end %>
+```
+
+### Generating a REST-style URL map (all entities → list & detail)
+```erb
+# migration_log.md
+<% @migrations.each do |m| %>
+### <%= Time.at(m['time'] / 1000).utc.strftime('%Y-%m-%d %H:%M:%S') %>
+
+<% m['changes'].each do |ch| %>
+- **<%= ch['type'] %>** on **<%= ch.dig('payload','table') || ch['tables'] %>**
+<% end %>
+
+<% end %>
+```

+#### Run App on local machine:
+
+##### Install local dependencies:
+- `yarn install`
+
+------------
+
+##### Adjust local db:
+###### 1.  Install postgres:
+ - MacOS:
+   - `brew install postgres`
+
+- Ubuntu:
+  - `sudo apt update`
+  - `sudo apt install postgresql postgresql-contrib`
+
+###### 2. Create db and admin user:
+ - Before run and test connection, make sure you have created a database as described in the above configuration. You can use the `psql` command to create a user and database.
+   - `psql postgres --u postgres`
+
+- Next, type this command for creating a new user with password then give access for creating the database.
+  - `postgres-# CREATE ROLE admin WITH LOGIN PASSWORD 'admin_pass';`
+  - `postgres-# ALTER ROLE admin CREATEDB;`
+
+- Quit `psql` then log in again using the new user that previously created.
+  - `postgres-# \q`
+  - `psql postgres -U admin`
+
+- Type this command to creating a new database.
+  - `postgres=> CREATE DATABASE db_456;`
+
+- Then give that new user privileges to the new database then quit the `psql`.
+  - `postgres=> GRANT ALL PRIVILEGES ON DATABASE db_456 TO admin;`
+  - `postgres=> \q`
+

+
+#### Api Documentation (Swagger)
+
+http://localhost:8080/api-docs (local host)
+
+http://host_name/api-docs
+
+------------
+
+ ##### Setup database tables or update after schema change
+ - `yarn db:migrate`
+
+ ##### Seed the initial data (admin accounts, relevant for the first setup):
+ - `yarn db:seed`
+
+ ##### Start build:
+ - `yarn start`

+## Description:
+
+  The project contains the **docker folder** and the `Dockerfile`.
+
+  The `Dockerfile` is used to Deploy the project to Google Cloud.
+  
+  The **docker folder** contains a couple of helper scripts:
+  
+- `docker-compose.yml` (all our services: web, backend, db are described here)
+- `start-backend.sh` (starts backend, but only after the database)
+- `wait-for-it.sh` (imported from https://github.com/vishnubob/wait-for-it)
+
+    > To avoid breaking the application, we recommend you don't edit the following files: everything that includes the **docker folder** and `Dokerfile`.
+
+
+  ## Run services:
+
+  1. Install docker compose (https://docs.docker.com/compose/install/)
+
+  2. Move to `docker` folder. All next steps should be done from this folder.
+  
+     ``` cd docker ```
+  
+  3. Make executables from `wait-for-it.sh` and `start-backend.sh`:
+  
+     ``` chmod +x start-backend.sh && chmod +x wait-for-it.sh ```
+  
+  4. Download dependend projects for services.
+  
+  5. Review the docker-compose.yml file. Make sure that all services have Dockerfiles. Only db service doesn't require a Dockerfile.
+  
+  6. Make sure you have needed ports (see them in `ports`) available on your local machine.
+  
+  7. Start services:
+  
+     7.1. With an empty database `rm -rf data && docker-compose up`
+  
+     7.2. With a stored (from previus runs) database data `docker-compose up`
+  
+  8. Check http://localhost:3000
+  
+  9. Stop services:
+  
+     9.1. Just press `Ctr+C`
