npm run build base-href

Using NPM to specify base-href When building an Angular application, people usually use "ng" and pass arguments to that invocation. Typically, when wanting to hard code "base-href" in "index.html", one will issue: ng build --base-href='https://ngx.rktmb.org/foo' I used to build my angular apps through Bamboo or Jenkins and they have a "npm" plugin. I got the habit to build the application with "npm run build" before deploying it. But the development team once asked me to set the "--base-href='https://ngx.rktmb.org/foo'" parameter. npm run build --base-href='https://ngx.rktmb.org/foo did not set the base href in indext.html After looking for a while, I found https://github.com/angular/angular-cli/issues/13560 where it says: You need to use −− to pass arguments to npm scripts. This did the job! The command to issue is then: npm run build -- --base-href='https://ngx.rktmb.org/foo&

Emacs TypeScript Development

Emacs Configuration for Typescript In order to comfortably develop on Node, React or Angular projects with Emacs, TIDE is a good solution. We have TypeScript code highlight (that is the minimum!) and code completion based on the codebase (not only on locally defined and builtins) In order to achieve that: Install Emacs (24+) Install Node Install Typescript (which will provide "tsserver") Install TIDE and some usefull dependencies Configure Emacs to use all those Node is then installed in " /home/mihamina/Apps/node-v12.18.0-linux-x64/bin ": you should add it to your PATH. Installing Typescript is done with: npm install --save typescript @types/browserify After that, "tsserver" will be in " /home/mihamina/node_modules/.bin " Then comes the installation of TIDE: With the Emacs package manager, M-x package-install , install "tide". Do the same for "web-mode", "flycheck", "company" "js2-mode" and "
