1. Install JSS:

npm install -g @sitecore-jss/sitecore-jss-cli

  1. create default react app - runs in Chrome:

jss create jss-react-app react

cd jss-react-app

jss start

  1. create default angular app and attempt to run:

jss create jss-angular-app angular

cd jss-angular-app

jss start

Expected: build and run, just like react app

Observed: cannot build due to build error.

chunk {main} main.js, main.js.map (main) 3.26 kB [entry] [rendered]

ERROR in node_modules/apollo-angular/types.d.ts(9,58): error TS2304: Cannot find name 'Exclude'. src/app/jss-graphql.service.ts(3,10): error TS2305: Module '"C:/Test/jss-angular-app/node_modules/apollo-angular/types"' has no exported member 'TypedVariables'.

Gotta be something stupid on my part, since I can't find anything on the web about this error. Thanks!

Pin your apollo-angular version to exactly 1.1.1 in the package.json (remove the ^), then run npm i again:


Unfortunately if packages are installed without a lock file (i.e. using npm since the sample ships with a yarn lockfile) to limit using newer versions the apollo-angular is installed with a version designed for a later version of Angular than the app has.


I figured out that TypedVariables last existed in apollo-angular in version 1.4, so I pinned that version. Then I got an error where Exclude wasn't defined, so I pinned typescript to 2.9.2. Therefore, after creating the default angular app and changing to that folder, run:

npm install [email protected] --save-exact

npm install [email protected] --save-exact

BEFORE trying to build and start the app and it will build and run just fine.
