This is one of two repos that will help you get started with Lightning Out in Visualforce and Node.js application to render Lightning Components both Aura and LWC.

This repo contains the Node.js server built using Typescript, express and ejs.

The two GitHub projects are:

• https://github.com/eltoroit/ET_LWC_Out_NodeJS
• https://github.com/eltoroit/ET_LWC_Out_Salesforce

Make sure you get both repos, then get the scratch org ready and execute the Node.js server.

• Create a scratch org by executing this command ./@ELTOROIT/scripts/CreateOrg.sh
• At the end of that script, it creates the pasword for the user and displays some important information. Make sure you keep that open (if you close it, you can execute sfdx force:user:display).
• On the Scratch org that was created, reset the security token for API connections.

• First, rebuild the node_modules folder by executing npm install
• Open VS Code and find the .env file
• Update the content using the information at the end of the script that creates the scrach org and the security token.
• Start the web server, by hitting F5
• Once it has compiled, open a web browser and navigate to either http://localhost:5000 or https://localhost:5001

Note: The Node.js web server is using a self-signed certificate which is required for HTTPS, but obviously is not secured. When you open the "secured" site, the browser is going to report a warning but you can bypass it and get to the content. When you deploy this to a real server, and use a good certificate, this problem will not happen any more.

Great question...

First of all, I am very excited about everything that came out on Summer '19 around LWC, specially Lighting Out because my site (http://ELTORO.IT) was build using this many years ago with Aura.

Second, it was a bit more difficult than I had thought... specially because there is not a lot of information and I used quite a long list of technologies (Node.js, Typescript, express, ejs, SSL certificates, Lightning out, ...) to put this together. I just want to share this solution with you, and hopefully help you save all the time I spent putting this together.

This uses two GitHub projects:

• https://github.com/eltoroit/ET_LWC_Out_NodeJS
• https://github.com/eltoroit/ET_LWC_Out_Salesforce
