使用声明合并失败扩展快递 object

Question

I am trying to add some properties to the Express/Request object, and everything seems fine but when I try to compile with tsc I get this error: error TS2339: Property 'id' does not exist on type 'Request<ParamsDictionary, any, any, ParsedQs>'.

I've tried all the answers found in this post Extend Express Request object using Typescript , but none of them seem to work for me.

In my root folder I created this:

 @types/express/index.d.ts declare module Express { export interface Request { id: number user_spotify_id: string access_token: string refresh_token: string } }

I also added the types folder to the tsconfig.json file:

"typeRoots": ["@types", "node_modules/@types"]

This is my callback function for the controller:

 async getPlaylists(req: Request, res: Response) { const { id } = req const query = `SELECT * FROM playlist WHERE user_id = $1` const { rows: playlists }: { rows: IPlaylistAll[] } = await db.query(query, [id]) return res.json(playlists[0]) },

I am able to get the id from the request object, and it even says the type is number, but when compiling I get the error I mentioned before.

Look, I was with this problem, I managed to solve it by changing the --transpileOnly flag to --transpile-only in package.json, check the version you are using of TypeScript, mine is 3.9.6.

And it was not necessary to configure tsconfig.json for min.
