What is it?
NodeJS is great for the rapid development of web-projects, but is often neglected because of the lack of type safety. TypeScript solves this issue and (along with its linter file) can even make your code more robust than some other static languages like Java.
There are some other tools out there to generate express apps with TypeScript such as express-generator-ts, but these either haven't been updated in a while or install a lot of junk in your project (such as an ORM).
Due to the heavy use of single-page-applications, no view-engine is configured by default. Express is only setup with the minimal settings for calling APIs and serving an index.html file. All the tools you need to run for development (while restarting on changes), building, testing, and running for production are packaged with this library.
In addition, relative paths are also setup, so you don't have to go through the trouble of installing
and configuring tsconfig-paths and module-alias. Just make sure to update
paths in tsconfig.json
_moduleAliases in package.json if you want to add/edit the relative paths.
When you run express-generator-typescript, it sets up a very simple application with routes for adding, updating, deleting, and fetching user objects. This is just to demonstrate how routing is done with express.
If you want a fully-secure application, you can pass the
--with-auth option and you will have an
application which requires you to logon before calling APIs on user objects. The app is
configured with production quality client-side security and uses signed-cookies and jsonwebtokens
to store user-session data. If you're new to web-development and still learning about securing websites,
I highly encourage to use this option.
$ Just use 'npx' Or $ npm install -g express-generator-typescript
The quickest way to get started is use npx and pass in the name of the project you want to create. If you don't specify a project name, the default express-gen-ts will be used instead.
Create the app:
$ npx express-generator-typescript "project name (default is express-gen-ts)" OR $ npx express-generator-typescript --with-auth "project name (default is express-gen-ts)"
Start your express-generator-typescript app in development mode at
$ cd "project name" && npm run start:dev
Available commands for the server.
- Run the server in development mode:
npm run start:dev.
- Run all unit-tests:
- Run a single unit-test:
npm test -- --testFile="name of test file" (i.e. --testFile=Users).
- Check for linting errors:
npm run lint.
- Build the project for production:
npm run build.
- Run the production build:
- Run production build with a different env file
npm start -- --env="name of env file" (default is production).
During development, express-generator-typescript uses
nodemon to restart the server when changes
are detected. If you want to enable debugging for node, you'll need to modify the nodemon configurations.
This is located under
package.json for the server and
unit-testing. For the
exec property, replace
node --inspect -r ts-node/register.
Note for windows users
If you use the
--with-auth option and are on Windows, the
bcrypt module tends to be fussy. To
use this module on Windows you need to make sure you have the node Windows build tools installed.
I don't want to post instructions because they might change frequently. I would search the Microsoft
docs on how to setup Node for Windows. To be able to debug in VSCODE on windows I also had to install
node-gyp module globally as well.
Happy web-deving :)
