From 108eec139d961e7549ab0572be5a56d2cd774eb8 Mon Sep 17 00:00:00 2001 From: oat Date: Wed, 2 Sep 2020 21:30:23 +0300 Subject: [PATCH] file parsing!! you can now just drop in a zip in /upload and it'll parse, handle and upload everything for you right now only the metadata is saved, so the actual file downloads aren't available, but that shouldn't be too hard to implement this is really hacky however, and dropping in a file with a malformed .sm or 2 .sms will likely make it have a panic attack definetly needs lots and lots of testing, it barely works --- package-lock.json | 5 ++++ package.json | 1 + src/index.ts | 16 ++++++------- src/lib/smparse.ts | 57 ++++++++++++++++++++++++++++++++++++++++++++++ src/schema.ts | 13 ++++++----- src/upload.ts | 48 +++++++++++++++++++++++++++++++++++--- 6 files changed, 122 insertions(+), 18 deletions(-) create mode 100644 src/lib/smparse.ts diff --git a/package-lock.json b/package-lock.json index 15b608d..9ec1de8 100644 --- a/package-lock.json +++ b/package-lock.json @@ -1499,6 +1499,11 @@ "resolved": "https://registry.npmjs.org/negotiator/-/negotiator-0.6.2.tgz", "integrity": "sha512-hZXc7K2e+PgeI1eDBe/10Ard4ekbfrrqG8Ep+8Jmf4JID2bNg7NvCPOZN+kfF574pFQI7mum2AUqDidoKqcTOw==" }, + "node-stream-zip": { + "version": "1.11.3", + "resolved": "https://registry.npmjs.org/node-stream-zip/-/node-stream-zip-1.11.3.tgz", + "integrity": "sha512-GY+9LxkQuIT3O7K8BTdHVGKFcBYBy2vAVcTBtkKpu+OlBef/NSb6VuIWSyLiVDfmLMkggHeRJZN0F3W0GWU/uw==" + }, "on-finished": { "version": "2.3.0", "resolved": "https://registry.npmjs.org/on-finished/-/on-finished-2.3.0.tgz", diff --git a/package.json b/package.json index 74fb601..b3188f9 100644 --- a/package.json +++ b/package.json @@ -17,6 +17,7 @@ "express-fileupload": "^1.2.0", "mongoose": "^5.10.2", "mongoose-int32": "^0.4.1", + "node-stream-zip": "^1.11.3", "typescript": "^4.0.2", "winston": "^3.3.3" }, diff --git a/src/index.ts b/src/index.ts index 16d87d1..cc1f8e9 100644 --- a/src/index.ts +++ b/src/index.ts @@ -58,15 +58,13 @@ db.then(() => { app.get('/list', async (req, res) => { // only for testing const docs = await File.find({}); - const map = docs.map(d => { - const keys = Object.keys(d.toObject()).filter(k => !k.startsWith('_')); - const obj = {}; - for (const key of keys) obj[key] = d[key]; - - return obj; - }); - - res.send(JSON.stringify(map)); + + res.send(docs.map((doc: any) => + `${doc.artist} - ${doc.title} by ${doc.credit}
