kandi X-RAY | lerna Summary

lerna is a TypeScript library typically used in Blockchain applications. lerna has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

Splitting up large codebases into separate independently versioned packages is extremely useful for code sharing. However, making changes across many repositories is messy and difficult to track, and testing across repositories becomes complicated very quickly. To solve these (and many other) problems, some projects will organize their codebases into multi-package repositories (sometimes called monorepos). Projects like Babel, React, Angular, Ember, Meteor, Jest, and many others develop all of their packages within a single repository. Lerna can also reduce the time and space requirements for numerous copies of packages in development and build environments - normally a downside of dividing a project into many separate NPM packages. See the hoist documentation for details.

            How to filter NPM commands to a pattern of workspaces (like filter, include, exclude, glob, grep or subdirectory)?
            Asked 2022-Mar-25 at 13:38

            I'd like to organise a large NPM monorepo such that I can run commands on many (but not all) workspaces according to a category or pattern.

            This could be by subdirectory, or by a pattern in the workspace names like a prefix or suffix, but I can't see any way to do either in NPM alone.

            In Yarn >= 2, this is possible using --include or --exclude flags with glob patterns on yarn workspaces foreach, for example:



            Answered 2022-Mar-22 at 10:06

            It's not documented (at time of asking), but NPM can filter workspace commands to subdirectories of workspaces by giving the --workspace flag a path as its value. For example:

            Puppeteer create PDF files from HTML data hangs Windows 10 system
            Asked 2022-Feb-17 at 11:58

            I created an App that processes students results by extracting data from multiple excel workbooks. The problem is that using Puppeteer to generate the PDF files, throws the system into a loop till it hangs the system.

            Actually, I have tested same codes below using PhantomJs which is bundled as pdf-creator-node, and was able to generate 150 PDF files comfortably in 3 minutes. The only challenge I dumped PhantomJs is that all the styling in the CSS file was not included, even when I inserted it as an inline style in the header, suing replace function of JS. Another, is that PhantomJs is no longer in active development. I searched the web, and found out that only Puppeteer is the valid solution with active development and support too.

            I tried using page.close() at the end of pdfCreator() which is in a loop, and browser.close() at the end of pdfGenerator(). What I am doing wrong?

            Here below are the codes in the server.js and PdfGenerator.js files, with a sample of the ERROR, and screenshot of my Task Manager after the system crawled out of hanging state. For HTML generation, I used Mustache. I excluded some lines of codes in server.js because the total character count was over 60k.

            Example solution (limiting parallel browsers)

            I created you a PdfPrinter class which you can integrate into your setup. It allows you to limit the amount of parallel pdf generation jobs and allows setting a limit and manages opening/closing the browser for you. The PdfPrinter class is also highly coupled and needed some modification for using it as a general queue. Logicwise this can be modified to be a general queue.

            You can try to integrate that into your code. This is a fully working test example with simplified pdfs (without the part of getting the actual data from the excel..)

            As far as I understood your code, you do not need to pass the page around all your functions. First create your html + css and then use the pdfPrinter and let it handle page creation + browser launching..

            (I like to code stuff like this so I went straight ahead..)

            Vercel deployment error: Module Not Found remotelly works locally. Cached build is the problem?
            Asked 2022-Jan-06 at 13:52

            I'm making this site using Next.JS hosted @ Vercel. One of the packages I'm using is a custom one that I've forked, updated it in my project and after the build, was able to make it work locally. I posted a question here about it.

            However, deploy is failing on Vercel's side with a message complaining that that same custom module I'm using couldn't be found. Everything works fine locally.

            There @react-headroom dependency in your package.json points to a github link rather than a dependency version. That seems to be the issue.

            You didn't do anything wrong -- the default behavior of pipelines is to checkout a commit, not a branch, thus detaching HEAD. I'm not familiar with Lerna or what "publish" does, so I can't tell you if what you're trying to do is going to be a bad idea or not, but you can simply checkout the appropriate branch before running the command.

            Is there a way to include only one module in the bundle?
            Asked 2021-Nov-28 at 18:21

            I'm building a microservice backend with lerna, parcel and docker. I have multiple microservices, which each rely on some common code in a “commons” package in the monorepo.

            This commons package is never published to NPM. Therefore, it works fine in development, but as soon as I try to build the docker containers, the commons module is not available inside the containers.

            Is there some way to tell parcel to externalize all dependencies (like it does by default on nodejs) except for the commons package? Is this possible?

            You can mark a particular package for inclusion in the bundle by using the includeNodeModules option. For example, In the package.json of the project that you want output a bundle that includes commons package rather than simply referencing it, you would have:
