Aws-sdk-js: Aws-Sdk + Typescript

[dhawalmewada]

My Ionic 2 (typescript) based project was working fine till now, suddenly when I fired command 'ionic build' I was surprised to get multiple errors.

Here is my tsconfig.json file :

{ "compilerOptions": { "allowSyntheticDefaultImports": true, "declaration": false, "emitDecoratorMetadata": true, "experimentalDecorators": true, "lib": [ "dom", "es2015" ], "module": "es2015", "moduleResolution": "node", "sourceMap": true, "target": "es5", "typeRoots": [ "../node_modules/@types" ] }, "include": [ "src/**/*.ts" ], "exclude": [ "node_modules", "src/**/*.spec.ts", "src/**/__tests__/*.ts" ], "compileOnSave": false, "atom": { "rewriteTsconfig": false } }

I don't know but there isn't any tsconfig.app.json file in 'src' folder (I even tried creating manually and adding configurations like type=["node"], etc But it gave me same error

Can anyone please help me

[chrisradek]

@dhawalmewada
That issue looks like what I'd expect if you didn't have node typings installed.

Can you verify that node typings exists for your project? If they don't, you can install them as a dev dependency:
npm install --save-dev @types/node

[dhawalmewada]

@chrisradek

It's already there.

I even tried removing it and keeping it in tsconfig.app.json (which I manually created) into src folder but nothing helped.

[dhawalmewada]

@chrisradek , Following are my version information, in case if you require
var IonicDevServerConfig={"sendConsoleLogs":false,"wsPort":53703,"appScriptsVersion":"3.1.2","systemInfo":["Ionic Framework: 3.9.2","Ionic App Scripts: 3.1.2","Angular Core: 5.0.1","Angular Compiler CLI: 5.0.1","Node: 6.11.4","OS Platform: Windows 10"]};

@dhawalmewada

Were you able to get this resolved? I'm curious if you have the same issue with a current version of the SDK and Ionic 2?
