Think I found a bug

After adding Angular Fire to my project, which I have created with angular-cli, I get the following errors when I start the app with ng serve:

Hi @daslicht, can you please update your issue to follow the template? There are many fields missing that would be helpful.

Can you also provide your tsconfig.json?

[dabele91]

Hi @daslicht, as mentioned in the change log, you have to remove the firebase typings from the tsconfig. I've received the same errors, but removing firebase from the tsconfig.json solved the problem.

Note from the change log:

A TypeScript issue with the previous release has been fixed, where errors about a missing firebase namespace were reported. For applications that worked around this issue by manually adding the firebase.d.ts typings to tsconfig.json, those typings should now be removed since the firebase namespace should automatically be resolved within AngularFire. See this issue for more context.

[davideast]

@dabele91 This is my guess as well. @daslicht Let me know if that works.

[AdamJo]

Seems to work fine when starting new. I'm currently trying to duplicate the error on a blank template using qdouble's minimal starter but no luck.

Here is my repo that has the error.

This is my tsconfig.json with the repo I am getting errors with. I deleted my /dll and /node_modules folder and the problem persists.

Windows 10 - Note: I do not have firebase in my tsconfig.

I had the same problem as @daslicht after upgrading an existing project from beta.5 to beta.6.

To fix this remove "types": [ "firebase" ] from your tsconfig.json file. Then delete your node_modules folder and npm install again.

Problem solved.

[davideast]

@edoardoVD Have you installed Firebase types from npm install @types/firebase? Because that would provide duplicate typings as the npm package ships with the typings.

If not try deleting your node_modules and re-installing.

[jwuliger]

For me I was installing the Firebase SDK and AngularFire2 via NPM. Now it seems that I can't use the latest Firebase SDK v3.5.3, but only the one that is included with AngularFire2 (v3.3.0). Each install was conflicting with each other. @davideast will there be a way to use the new Firebase SDK in the future? Thanks!

[AdamJo]

Removing Firebase from my package.json dependencies like @jwuliger suggested worked for me. I am no longer getting the errors.

@davideast : On a side note, this new release reduced my production build (with AOT) from 338kb to 233kb. Thanks for all the work you and the rest of the team are doing with AngularFire2.

[edoardoVD]

@davideast nope, I have not installed firebase types
@AdamJo, I have also removed "firebase": "^3.5.3" from the package.json, ran npm prune, ng build all is good.

Even though I was getting the console screaming bloody murder error messages, the app was compiling and working ( when I still had , "firebase": "^3.5.3" on the package.json)

And by the looks of the inner content of angularfire2 beta 6 npm package (node_modules\angularfire2\node_modules\firebase\package.json) its using "firebase@3.3.0", I guess in the near future we will see using the latest version

Cheerio
edo@rdo

[jek-bao-choo]

I had the same problem. Based to @davideast suggestion, I did npm uninstall @types/firebase. This solved the problem.

[katowulf]

I just did a fresh build using the latest versions and had no issues, even after running npm install --save firebase angularfire2 and then ng build.

Possible solutions that worked for others:
@jwuliger noted that AngularFire2 requires Firebase SDK ^3.3.0 and installing via npm gives ^3.5.3 (not compatible apparently)
@choopage used npm uninstall @types/firebase
@edoardoVD removed firebase from package.json, then npm prune
