SASjs Server

SASjs Server provides a NodeJS wrapper for calling the SAS binary executable. It can be installed on an actual SAS server, or it could even run locally on your desktop. It provides the following functionality:

• Virtual filesystem for storing SAS programs and other content
• Ability to execute Stored Programs from a URL
• Ability to create web apps using simple Desktop SAS

One major benefit of using SASjs Server (alongside other components of the SASjs framework such as the CLI, Adapter and Core library) is that the projects you create can be very easily ported to SAS 9 (Stored Process server) or Viya (Job Execution server).

Configuration

Configuration is made in the configuration section of package.json:

• Provide path to SAS9 executable.

Using dockers:

There is .env.example file present at root of the project. [for Production] There is .env.example file present at ./api of the project. [for Development] There is .env.example file present at ./web of the project. [for Development] Remember to provide enviornment variables.

Development

Command to run docker for development:

docker-compose up -d

It uses default docker compose file i.e. docker-compose.yml present at root. It will build following images if running first time:

• sasjs_server_api - image for sasjs api server app based on ExpressJS
• sasjs_server_web - image for sasjs web component app based on ReactJS
• mongodb - image for mongo database
• mongo-seed-users - will be populating user data specified in ./mongo-seed/users/user.json
• mongo-seed-clients - will be populating client data specified in ./mongo-seed/clients/client.json

Production

Command to run docker for production:

docker-compose -f docker-compose.prod.yml up -d

It uses specified docker compose file i.e. docker-compose.prod.yml present at root. It will build following images if running first time:

• sasjs_server_prod - image for sasjs server app containing api and web component's build served at route /
• mongodb - image for mongo database
• mongo-seed-users - will be populating user data specified in ./mongo-seed/users/user.json
• mongo-seed-clients - will be populating client data specified in ./mongo-seed/clients/client.json

Using node:

Development (running api and web seperately):

API

Navigate to ./api There is .env.example file present at ./api directory. Remember to provide enviornment variables else default values will be used mentioned in .env.example files Command to install and run api server.

npm install
npm start

Web

Navigate to ./web There is .env.example file present at ./web directory. Remember to provide enviornment variables else default values will be used mentioned in .env.example files Command to install and run api server.

npm install
npm start

Development (running only api server and have web build served):

API server also serving Web build files

There is .env.example file present at ./api directory. Remember to provide enviornment variables else default values will be used mentioned in .env.example files Command to install and run api server.

cd ./web && npm i && npm build && cd ../
cd ./api && npm i && npm start

Production

API & WEB

npm run server

This will install/build web and install api, then start prod server.

Executables

Command to generate executables

cd ./web && npm i && npm build && cd ../
cd ./api && npm i && npm run exe

This will install/build web app and install/create executables of sasjs server at root ./executables
