Axios vs Fetch: How to Evaluate Chinese Migration Tutorials

Start with the behavior your application needs

A persuasive recommendation to replace Axios with Fetch is a starting point for a review, not a migration specification. Write down your runtime, exact dependency version, selected adapter, supported browsers and required request behavior. Then compare the existing client and proposed replacement against the same small set of examples.

This guide is for English-speaking developers reading Chinese frontend tutorials through translation. Its worked example is an October 20, 2026 Juejin post by ErpanOmer advocating Fetch in the author's team. We read that article and the official references on October 22. The useful addition here is a behavior checklist and a specific cancellation pitfall, rather than a vote for either library.

Translate the technical question before the recommendation

Keep identifiers such as Axios, Fetch, AbortController, CancelToken and responseType unchanged when translating prose. Three useful Chinese terms are 拦截器 (lánjiéqì), an interceptor that runs around a request or response; 超时 (chāoshí), a timeout; and 取消 (qǔxiāo), cancellation. Translate a claim about one of these behaviors into an observable question before accepting the author's conclusion.

For example, ask whether an interceptor injects authentication, transforms response data or retries a request. A replacement must make an intentional decision about each behavior. A shorter wrapper is not equivalent merely because its successful GET example returns the same JSON.

Check the Axios adapter before accepting a streaming claim

The Axios project documents a Fetch adapter introduced in version 1.7.0. Its current documentation describes selecting adapter: 'fetch' explicitly and supporting stream responses where the environment provides them. A blanket claim that Axios cannot stream therefore needs qualification by version, adapter and runtime.

Record those three details together. If a tutorial discusses XMLHttpRequest limitations, check whether your application actually selects that adapter. If it discusses a server runtime, review that runtime separately. Documentation of an available adapter does not prove that it works with your application's authentication, upload workflow or deployment bundle; test the configuration you intend to ship.

Make HTTP errors and response bodies part of the contract

Fetch separates receiving an HTTP response from your application's acceptance of its status. The Fetch Standard defines an OK status as 200 through 299. Axios exposes a configurable validateStatus rule, with a default accepting that range. Inspect your existing configuration rather than assuming every Axios application uses the default.

Write down what callers should receive for 200 with JSON, 204 without a body, 401, 429 and 500. Decide whether an error preserves the status and response body and whether an empty success response should be parsed as JSON. Keep HTTP success, JSON parsing and your business-level success field as separate checks. These are proposed acceptance cases, not results from a migration we executed.

A caller signal can accidentally remove a timeout

The example wrapper in the Juejin article chooses config.signal ?? AbortSignal.timeout(timeout). When a caller supplies a signal, that expression selects it instead of creating the fallback timeout. If the intended contract is both caller cancellation and a deadline, this expression does not combine the two conditions.

The DOM Standard provides AbortSignal.any to create a signal dependent on supplied signals. Where supported by your target runtime, combining a caller signal and a timeout signal can express the either-condition rule. Also define how your fallback implementation removes listeners and timers, and test older embedded browsers you support.

Our isolated Node.js 24.15.0 check passed four assertions: the deadline aborted, the caller-selected signal initially remained active, the combined signal aborted, and manually aborting the caller then aborted its selected signal. This checks local signal semantics only. It makes no HTTP request and does not test Axios, the author's complete wrapper, browser compatibility or network performance.

Separate a deprecated API from a deprecated library

Axios documents AbortController support from version 0.22.0 and deprecates its older CancelToken API. Finding CancelToken in a project is a reason to inspect cancellation code; it does not establish that the entire Axios library is deprecated or that replacing it is the least costly fix.

Compare two concrete changes: update the legacy cancellation path while retaining the client, or migrate a bounded set of endpoints to another client. Estimate the behavior that must be preserved, review a representative diff and retain a way to revert. The right choice depends on your application, not the strength of a tutorial's headline.

Keep an evidence note you can revisit

Save the source URL, displayed publication date, author, dependency version, adapter and runtime. Add each recommendation, its official reference, the relevant application behavior and the test you actually ran. Keep intended tests separate from passed tests. Record bundle or performance improvements only after measuring your own before-and-after build or workload.

A ranking observation cannot show how many teams followed the recommendation. This guide is an original reading and evaluation aid, not a full translation or an audit of the author's application.
