ts-node: Property 'body' does not exist on type 'Request'.
See original GitHub issueProblem/Feature Request Summary
There seem to be something wrong with the typings of koa-body
. You sometimes get unexpected results when used together with ts-node:
/Users/m41n/source/repos/koabody/node_modules/ts-node/src/index.ts:261
return new TSError(diagnosticText, diagnosticCodes)

I think its the defect of ts-node, similar problem occurs to me. For the same project:
tsc
will compile without errorts-node
will get: error TS2459: Type ‘Request’ has no property ‘body’ and no string index signatureI tried to add additional config to
tsconfig.json
, and then the error disappeared:It is because
tsc
could findnode_modules/koa-body/index.d.ts
, butts-node
can’t.ts-node
will only searchd.ts
files undernode_modules/@types
.@MarkHerhold I think you can move
index.d.ts
to@types/koa-body
