![]() Seems obvious but a simple bit of configuration somewhere which is not set quite right can have you scratching your head. Unicorn Serialisation - if you're using it, ensure that there is nothing which is being tracked by unicorn in the content tree (or anywhere else) which a content author might be making updates to (and therefor writing to the unicorn file). On a local instance we're referring to these logs/artefacts which is controlled by the \App_config\Include\ file so set this to ".disabled" by default for PaaS environments. Logging - ensure you're using Application Insights and that all other logging is routed to AI and definitely not to the file system.ĭiagnostic logging - disable this for production environments and only enable if you have a need (I've never used this but it's enabled by default which caught me out). Sitecore on Azure PaaS File I/O errors "Too many changes at once in directory:D:\home\site\wwwroot\"Įach time I've had to trawl through the Azure Kudo powershell file system view looking for where on earth some files are being written to so I thought I'd share a couple of (seemingly obvious upon reflection) places where I've had to work around this. You can do that like this:ĬLI JS Go # The CLI does not have an API for "cancel" import * as esbuild from 'esbuild' import process from 'node:process' let ctx = await esbuild.During the move to Azure PaaS there have been a few instances where we've noticed a series of errors being logged about file I/O issues which often result in instances dying within a PaaS "load balancer". If you are using rebuild to manually invoke incremental builds, you may want to use this cancel API to end the current build early so that you can start a new one. If you really need to bundle code that does this, you will likely need to use another bundler instead of esbuild. However, run-time file system emulation is out of scope and will not be implemented in esbuild. Some bundlers such as Webpack try to support this by including all potentially-reachable files in the bundle and then emulating a file system at run-time. You will then need to ensure that a copy of the external package is available to your bundled code at run-time. ![]() The way to work around this issue is to mark the package containing this problematic code as external so that it's not included in the bundle. Import * as esbuild from 'esbuild' let result = await esbuild.build(`) Here's a simple example that enables bundling with an output directory:ĬLI JS Go esbuild app.ts -bundle -outdir=dist You typically pass one or more entry point files to process along with various options, and then esbuild writes the results back out to the file system. This is the primary interface to esbuild. Each is described below at a high level, followed by documentation for each individual API option. ![]() The two most commonly-used esbuild APIs are build and transform. There is separate documentation for both of the public Go packages: pkg/api and pkg/cli. Go: If you are using Go, you may find the automatically generated Go documentation for esbuild helpful as a reference. You may also find the TypeScript type definitions for esbuild helpful as a reference. JavaScript: If you are using JavaScript be sure to check out the JS-specific details and browser sections below. The form -foo is used for enabling boolean flags such as -minify, the form -foo=bar is used for flags that have a single value and are only specified once such as -platform=, and the form -foo:bar is used for flags that have multiple values and can be re-specified multiple times such as -external. Some specifics for each language:ĬLI: If you are using the command-line API, it may be helpful to know that the flags come in one of three forms: -foo, -foo=bar, or -foo:bar. You can switch between languages using the CLI, JS, and Go tabs in the top-right corner of each code example. The concepts and parameters are largely identical between the three languages so they will be presented together here instead of having separate documentation for each language. The API can be accessed in one of three languages: on the command line, in JavaScript, and in Go.
