The following snippet shows a typescript error at LINE 4:
import {Message} from './class/message';
function sendPayload(payload : Object) : any{
let message = new Message(payload);
console.log(message); // LINE 4
}
The error says:
[ts] Cannot find name 'console'.
What could be the reason for this? Why it cannot find the object console?
You will have to install the @types/node to get the node typings, You can achieve that by executing the below command,
npm install @types/node --save-dev
Hope this helps!
Add "dom" in your lib section in compilerOptions in tsconfig.json.
Example:
{
"compilerOptions": {
"rootDir": "src",
"outDir": "bin",
"module": "commonjs",
"noImplicitAny": false,
"removeComments": true,
"preserveConstEnums": true,
"sourceMap": true,
"target": "es5",
"lib": [
"es6",
"dom" <------- Add this "dom" here
],
"types": [
"reflect-metadata"
],
"moduleResolution": "node",
"experimentalDecorators": true,
"emitDecoratorMetadata": true
}
}
You can run npm install @types/node -D, and then you need to add types:[ 'node'] into your tsconfig.json also.
package.json
"devDependencies": {
"@types/node": "^15.0.3"
}
tsconfig.json
{
"compilerOptions": {
"composite": true,
"outDir": "./dist",
"rootDir": ".",
"declaration": true,
"noImplicitAny": true,
"esModuleInterop": true,
"module": "commonjs",
"target": "es6",
"types": [
"node"
],
"lib": [
"es6"
]
},
"exclude": [
"node_modules",
"dist"
]
}
