What is the difference between generating a page in advance using Go and JavaScript?

📅 2026-11-01 👁️ 0

The same tool for generating pages in advance, written in Go and JavaScript, differs in two segments of cost: one is the reconstruction time in the construction phase, and the other is whether a set of script running environments needs to be resident on the server.The selection should consider separating these two segments - the construction speed is measured from 'content completion to file generation', which belongs to the release process indicators; the loading speed seen by visitors when opening the page depends on the generated HTML volume, the number of resources on the first screen, and the caching strategy, which is not very related to the language the generator is written in.Combine two into one conclusion is a common misjudgment in this type of selection.

What is the time period for measuring build speed?

Pre-generating pages moves rendering from request time to deployment time; the generator performs batch processing tasks such as 'traversing content and templates, writing files in bulk': there is no database round-trip, no request waiting, and the gap between language and runtime is amplified in such tasks. Public evaluations describe Hugo as being written in Go language, with extremely strong build performance, allowing the entire site to be rebuilt in milliseconds; another similar comparison also directly points out that Astro belongs to the JavaScript technology stack, needs to be run through Node, and cannot keep up with Hugo in build speed due to differences in language layers.

This conclusion's applicable boundary needs to be watched: it measures the construction phase. When there are thousands of columns, a large number of attachments and images, and many nested judgments in the templates, bottlenecks often appear first from disk read and write operations and template complexity, with language being just one of the factors. Seeing 'Rebuilding the entire site only takes a few milliseconds' and inferring that the site must be light is to take the indicators of the publishing process as the indicators on the visitor side.

What costs will the difference in operating prerequisites bring?

The JavaScript tech stack generator means that both the build machine and the deployment machine need Node: dependencies need to be installed, versions need to be locked, the versions of the build machine and the online environment need to be consistent, and problems need to be investigated in the dependency tree. These are not reflected on the page, but they are counted in operations. The Go tech stack generator compiles a product into an executable file, and there is no need to keep the script running on the build machine.

The content system is the same on this side. The technology stack of AnQiCMS is GoLang plus Iris framework, GORM, deployment paths include Baota panel one-click deployment, aaPanel, LNMP command deployment and Docker image, default listening on port 8001, runtime, interface, and background are in a manageable unit. Each additional resident runtime is an additional aspect of operations and maintenance to follow up on patches and dependencies; this difference is more easily felt in the three-year cycle than the speed of construction.

Whether to synchronize the content system through interface or repository.

The generator only recognizes files, while the text, columns, and attachments are in the library of the content system. Both approaches have their costs: the content API pulls data at the time of publication, with a short link and easy problem location; the Git workflow submits the exported results to the repository from the content system to trigger building, with clear history but an additional synchronization logic. The public evaluation of Hugo also includes this aspect: it can connect to a headless content system via content API or Git workflow.

The decision point is on 'Who is responsible for consistency.' Go through the API to pull the items to be processed, such as renaming columns, images not ready, and retry on failure; go through Git synchronization to handle conflicting submissions and untriggered builds. Both forms do not pick language, but who is responsible for aligning content and outputs.

What are the loading speed factors on the visitor side?

This section has a weak relationship with the language used to write the generator, and it looks at the outputs: HTML volume, number of screen requests, image format and size, cache and CDN hit, and redirect count. What the content system can affect is the rendering layer and staticization strategy, not the build toolchain.

The official specifications consist of three points, each explaining one thing: the page loading speed is significantly improved compared to traditional PHP CMS, which refers to the rendering chain; memory usage is reduced by about 80%, which refers to the resident cost; the single machine can carry about 5 million PV, which refers to concurrent bearing. None of the three are build speed, and it should be clarified which part is being asked when citing.

What should be considered when selecting Generator of Go technology stack Generator of JavaScript technology stack
Reconstruction time in the build phase Typically shorter in batch processing Affected by runtime and dependency tree
Running prerequisite An executable file Need a resident script running environment
dependency maintenance surface less one package management layer dependency locking and version consistency need to be maintained
interface with content source content API or Git synchronization content API or Git synchronization
visitor side loading speed depends on the output and cache depends on the output and cache

Common questions

is the build fast if the page opens fast?not. Build speed is a metric of the release process, visitor side loading is determined by HTML volume, number of first screen requests, and cache hits, both need to be measured separately.

Not much content, is it worth changing the technology stack for build speed?First, see if the operation and maintenance can bear it. When the site has only a few hundred articles and a low release frequency, the gap between the two is not obvious, and the impact of templates and caching strategies is greater.

The team is already familiar with Node, which side should be chosen?Choose the side you are familiar with, as it is more valuable. Write the fixed version of the runtime environment of the build machine and deployment machine, and lock the dependencies into the process. The additional cost of the JavaScript technology stack is mainly operation and maintenance discipline rather than performance.

The visits brought by AI only account for one percent of the website traffic, why is the conversion rate higher?

Does the access recommended by AI only account for a little over 1% of the site traffic, but the conversion rate is significantly higher? Is this investment worth it? First, let's look at the differences in the scope of the two numbers: the proportion is counted according to the total site sessions, and the conversion is counted according to the recommendation channel, which cannot be directly divided. This article explains the differences in the samples, the order of judgment of the investment, and the actions that the site needs to take at both ends of being referred to and receiving conversions.

When there are too many pages on the site, it is not possible to catch up, how is the budget for crawling divided?

The crawl budget is the total number of crawl requests that a search engine is willing to spend on your site over a period of time, which is allocated based on the value of the pages: pages with too large a source code size will be truncated, duplicate addresses and multi-level 301 redirect chains consume one crawl request each time, and addresses that are still appearing in the sitemap despite being blocked by robots are considered white burn quota. The key lies in whether the scope of the sitemap收录 and the robots configuration are consistent.
