# Developer's Guide
We use Visual Studio Code for developing LoopBack and recommend the same to our
users.
## VSCode setup
Install the following extensions:
- [eslint](https://marketplace.visualstudio.com/items?itemName=dbaeumer.vscode-eslint)
- [prettier](https://marketplace.visualstudio.com/items?itemName=esbenp.prettier-vscode)
## Development workflow
### Visual Studio Code
1. Start the build task (Cmd+Shift+B) to run TypeScript compiler in the
background, watching and recompiling files as you change them. Compilation
errors will be shown in the VSCode's "PROBLEMS" window.
2. Execute "Run Rest Task" from the Command Palette (Cmd+Shift+P) to re-run the
test suite and lint the code for both programming and style errors. Linting
errors will be shown in VSCode's "PROBLEMS" window. Failed tests are printed
to terminal output only.
### Other editors/IDEs
1. Open a new terminal window/tab and start the continous build process via
`npm run build:watch`. It will run TypeScript compiler in watch mode,
recompiling files as you change them. Any compilation errors will be printed
to the terminal.
2. In your main terminal window/tab, run `npm run test:dev` to re-run the test
suite and lint the code for both programming and style errors. You should run
this command manually whenever you have new changes to test. Test failures
and linter errors will be printed to the terminal.
