Installation

git clone https://github.com/atherdon/dash-back
cd dash-back
yarn install

Rename .env.example to .env and set up your environment variables:

# 1 For Linux Database url (need change ${absPathToPWD} to /abs/path/to/project)
# 2 For Windows (file:./database/sqlite/dash.db)
DATABASE_URL=file://${absPathToPWD}/database/sqlite/dash.db
# List of allowed origins, in NODE_ENV !== production that origin is '*' everytime
CORS_ORIGIN=localhost,second.origin
# JWT token secret key
TOKEN_KEY=QpLwz7AqqUg0GU6VHLO31aR8zqoeMiJiYXIiLCJpY
# Public server url for app host via docker 
DOCKER_SERVER_URL=http://my.domain

Usage

Development

Start watch ts changes:

yarn ts

Start server:

yarn dev

Migration on development

Database migrations: src/prisma/migrations
Database schema: src/prisma/schema.prisma

Create new migration. This command delete all data from database:

yarn migrate:dev

Only delete data from database without create migration:

yarn migrate:reset

Get status of migrations:

yarn migrate:status

Types

GraphQL types
Types for GraphQL Schema created automatically with package @graphql-codegen. When changed src/graphql/Schema.ts. To create types into src/types/graphql/index.d.ts run yarn codegen or simple run gulp and generated file will be changed everytime when Schema.ts saved.

IDE settings

Local settings for vscode in .vscode/settings.json`

For highlight specified syntax need install vscode extensions:

dbaeumer.vscode-eslint
graphql.vscode-graphql
esbenp.prettier-vscode
prisma/prisma

Debug

To run server in debug console need set up file .vscode/launch.json

"runtimeExecutable": "~/.nvm/versions/node/v14.15.4/bin/node"

And run debug F5

Production

Attention!
Only Linux based OS support

Build and start

Build typescript:

yarn build

Run server in screen:

yarn prod
Or
Run build and prod commands: yarn deploy

Migration on production

Create database schemas from exists migrations:

yarn migrate

Test

File 'postman.json' in resources/postman

Start without screen in development mode:

yarn start

Start with environment variable NODE_ENV=test (in this case in result of requests added variable 'stdErrMessage'):

yarn prod:test

Before this command do not forgot yarn build

Production via Docker

Firewall settings:

Open port 80 (and 443 for ssl)

SSL certificate

Skip SSL settings
If needed SSL certificate do change file dockerfiles/web/Dockerfile:

## Set "nginx-ssl.conf" instead "nginx.conf" if needed SSL 
ARG USED_NGINX_CONF=./resources/nginx.conf
## If needed SSL do uncoment next lines and set paths to private and public parts of certificate 
# COPY .certs certs
# RUN chown nginx:nginx -R certs

Copy your SSL certificate parts in .certs directory, and change owner if needed:

chown user:user -R .certs

Check resources/nginx*.conf certificate part names:

# Set ssl paths
ssl_certificate /home/web/certs/nginx-selfsigned.crt; // Certs without "." is a path of ".certs" copy into container
ssl_certificate_key /home/web/certs/private/nginx-selfsigned.key;

Change protocol in .env:

# Public url for your server 
DOCKER_SERVER_URL=http://my.domain ## https if used SSL

End SSL certificate section

Then...
Build docker containers:

docker-compose build

Start containers for test:

docker-compose up

Start containers detach:

docker-compose up -d

Additions

For docker

Show logs:

docker logs

Connect to container:

docker exec -it name sh

For screen

Open database explorer

yarn studio

Show actual log (production):

yarn logs

Focus screen (production):

yarn focus

Start fill scripts

yarn script fill

Format Prisma scheme

yarn format

TODOS

  • auth0 as simple and lazy way to do a login
  • quick and simple deploys from pull requests(aws?)

front located here: https://github.com/atherdon/dashb

examples with data(durty version): https://github.com/atherdon/dash-back/data

  • stage 0: simple crud on graphql. we can use sqllite for speed
  • stage 1: authentification: to be discussed - simple for 10 ppl or BRAC with 2-3 roles
  • stage 2: csv/json import script
  • stage 3: simple additional functionality: search/filtration/basic calculations
