I have been running the same Loopback 4 projects on my PC for months, but a couple of days ago I start getting Typescript problems that I cannot find a resolution to.
When trying to run NPM START, I'm getting the following Typescript:
node_modules/@loopback/core/dist/src/keys.d.ts(27,40): error TS1005: '>' expected. node_modules/@loopback/core/dist/src/keys.d.ts(27,103): error TS1109: Expression expected. node_modules/@loopback/rest/dist/src/router/trie-router.d.ts(11,62): error TS1144: '{' or ';' expected. node_modules/@loopback/rest/dist/src/router/trie-router.d.ts(12,5): error TS1128: Declaration or statement expected. node_modules/@loopback/rest/dist/src/router/trie-router.d.ts(12,39): error TS1005: ';' expected. node_modules/@loopback/rest/dist/src/router/trie-router.d.ts(13,1): error TS1128: Declaration or statement expected.
The same code (project) runs just fine on another PC, so I'm thinking this is related to Typescript, but I have not been able to figure out the root cause, and therefore find a resolution on my own.
Update: I tried to run NPM UPDATE on my working environment, and it broke too, with the same TS-problems.
Maybe it's my package.json file, it was scaffolded using an beta-version of LB4, and manually updated.
"@loopback/boot": "^1.0.5",
"@loopback/context": "^1.1.0",
"@loopback/core": "^1.1.0",
"@loopback/openapi-v3": "^1.1.2",
"@loopback/openapi-v3-types": "^1.0.1",
"@loopback/repository": "^1.0.5",
"@loopback/rest": "^1.3.1",
"@loopback/rest-explorer": "^1.1.1",
"@loopback/service-proxy": "^1.0.2",
So - I finally figured out the reason behind my problems.
My project was scaffolded with an early version of the Loopback/cli back in July 2018, and the logic regarding the \dist folder was changed in index.js.
Some time during the last couple of weeks, a new logic has replaced the old dist-util, and this change broke my project.
I'm back now, but I have one un-resolved issue with the query parameter of Restbindings being empty. I will open a new thread for that.
