Working on a larger typescript project we decided to move the code to a monorepo with yarn workspaces.
We use webpack to build and bundle and everything works well (especially the linking between local modules/packages).
Since yarn workspaces will store most of the node_modules in the mono repo's root folder, the IDE (IntelliJ as well as VSCode) have problems resolving the imports to any node_modules when coding inside a "inner" project (so called "package" of a monorepo).
The strange thing is that imports are not known but on the other hand most of the time you can navigate to the correct source / definition within the IDEs for the same import if you write it down manually.
We have tried to tell IntelliJ to look into another folder for node_modules, but still not satisfying.
Please share your experience with yarn workspaces / monorepo (e.g. lerna) and how you develop the code living in these monorepos.
Which IDE do you use?
Did you add any special configurations to the IDE and/or package.json, tsconfig.json?
https://github.com/Izhaki/mono.ts
It uses yarn workspaces and marry well with VSCode. I hope the README is clear enough.
Basically, use two (parallel) typescript configuration trees:
Pre-build - uses aliases (for VSCode, tests, webpack, etc).
Build - uses typescript 3 project references for publishing essentially.
IDEA doesn't provide any support for Yarn workspaces; if you miss it, please follow WEB-29250 and linked tickets for updates.
You can try adding path mappings to your tsconfig.json - see https://intellij-support.jetbrains.com/hc/en-us/community/posts/207656825/comments/115000529564
Upodate as of 2018.1.1 IntelliJ now supports yarn workspaces so if you use this there should not be a problem.

Which IDE do you use?
Since you are asking. I basically ran into the same issues as you did. One solution I was looking into was disable hoisting node modules as described here. Unfortunately it seems it is not yet in the stable release.
What I ended up was ditiching workspaces for now until they fix either the IDE or release the nohoist option. Instead I am using lerna for now. It is less convenient but it does not hoist so that both the build tools and the IDE are satisfied.
Oh, I am also using IntelliJ (ultimate)

The current project is an older monorepo project, which uses yarn to manage dependency packages, and many subprojects use phantom dependencies. At present, the project is gradually migrating to pnpm, but there is a problem that each subproject uses many npm packages that are not in its own package.json. However, there are dozens of such sub-projects, and manual statistics are a very heavy workload. Is there any good tool that can help me find out all the npm packages that each sub-project depends on through text analysis? In this way, I can find all missing dependencies by comparing the subproject's package.json and add them to the subproject's package.json.
There is currently no good idea to solve this problem. In the search tool, if there is no such tool, consider using python to write a new one.
I want to take a stab at contributing code to TestCafe for bugs/issues.
Can anyone of the contributers help me with setting up my machine? How do you get started? (apart from forking the repo) Are there any tools/extension that specifically help you?
Node.js is a prerequisite and needs to be installed on your machine. You need to run npm install or yarn in the local copy of the repository after it is cloned. You can use gulp build to build the project without running tests. After the project is built, you can start TestCafe by executing node bin/testcafe.js <TestCafe args> in your terminal.
You can use any text editor of your choice. JetBrains Webstorm is an ultimate solution for a JS project like TestCafe, but it is paid and proprietary. Visual Studio Code is a good open-source and free alternative.
As for other questions, I suggest you refer to the Code Contribution section of our guide, which covers the majority of topics.
The manual states that
You can also install the package globally on your machine and use the
wdio directly from the command line. However it is recommended to
install it per project.
Why is that? What downfall should I worry if installing globally?
If you only wish to use webdriver only in your shell regardless of any project then you can install it globally. However, if you wish to use it in a project, such that it is required to run project tests then install it locally (in this case it should be devDependency). The reasons are:
1) When multiple people working on a project, it is ensured that all of them have the same versions of the required packages.
2) Portability. The project dependencies should be completely defined in package.json so that after running npm install the project is ready to use in every environment.
For people new to NPM and Node, I'd recommend a global install to keep it simple. There are reasons to install it locally though, mostly to do with version compatibility and ease of project sharing: https://www.joezimjs.com/javascript/no-more-global-npm-packages/
I was doing some experimenting with Gradle and created a multi-project build, with multiproject_test dependent on two projects ChildA and ChildB. I put this simple test project on GitHub.

Everything seems to be working great on the command line and Eclipse. Everything was compiling and the dependencies were being recognized and used. But when I imported the project into IDEA it did not create the dependencies. It seems like I had to manually create the modules although it did import the source code from the child projects.
My question is do I have to specify these module declarations separately in the build.gradle script for IDEA? Why would it not even compile the dependencies?
UPDATE
Solution proposed below worked great. IDEA handled the build.gradlescript much more gracefully than the idea plugin.
Loading a Gradle project to build an IDEA project by using the idea plugin does not always work well. The recommended way to load a Gradle project in IDEA is to import the build.gradle file from the root project.
More detailed instructions can be found in IDEA documentation here.
I recently started to use Maven2 in one of my Java web application projects. Now I had many issues with it, some times project fails to build for no apparent reason and then it suddenly starts to work when nothing was done at all to project. Or some times our project members must delete project from their harddrive and download project again from SVN. There seems to be many very odd bugs in Maven in eclipse, but there some issues I would like know if it is possible to solve this issues.
1) I have understood that Maven2 should be able to get dependencies for added jars, but when I add a new dependency in Eclipse, it fails when I build it, it says dependecies are missing. How can I make maven to download those missing dependecies automatically?
2) I have Tuckey UrlRewrite Filter in use, but public repositories have only old version of this dependecy, so when I use this old version (3.1 when I need 3.2). How can I include this to project? We have many programmers in this project, so setting up local repository would mean that all our programmers would have to install that local repository.

Ok and what is the point of this free rant? I use Maven and my builds are 100% reproducible, there are well known practices to follow to achieve this. Maybe you're just not following them. Anyway if you're not happy with it, what can I say, don't use it.

I think you misunderstood, Eclipse won't guess what Maven coordinates to add if you don't provide the required informations for them. Dependencies must be declared in the POM, either by editing the POM manually or by using m2eclipse wizards.
And if this is what you did (and if I misunderstood the question) then please provide the <dependency> declaration and the exact error trace.

This question has already been asked several times, see for example Maven, how to add additional libs not available in repo where I suggest two possible solutions (use a corporate repository like Nexus or a "file-based" repository, the former suggestion being the preferred one for a long term solution).
